[Q] USB Host Mode for Chinese Tablet - Android Q&A, Help & Troubleshooting

Hello XDA, I have a question, I recently got a chinese tablet that runs a direct port of the original android version, which im almost certain dosent support USB Host, howeve the tablet has A USB host port. I am curious if theres an app out there that supports USB host for keyboards and/or Flash drives. I like the idea of just plugging in my flash drives and viewing/editing my files on the go when I dont have my computer with me.
Thank you

Have you tried plugging in a USB device?
My Elf has an Micro USB OTG port and it came with a USB->Micro USB adapter. So far only my wireless receiver for mouse any keyboard didn't work

I have tried a variety of device, im assuming that this tablet was just loaded with the very basic android OS

That makes me wonder if the device connecting to the phone/tablet has to be externally powered

Just did a bunch of test, in which the USB device only got power from the tablet.
-8 GB USB key works
-Cheapo Genius mouse works
-Less cheapo Razer mouse works (Wow, the DPI difference is amazing!)
-When connecting cheapo Genius mouse to tablet via USB hub, the mouse's laser light's up, but it doesn't work.
(What would happen if I were to connect my phone to my tablet? (inb4 they both blow up))

Well it dosent seem to power it and in the heat of the moment the tablet was sitting right here beside me and I glance over at it and notice its not charging, I try to turn it on and turns out the little bugger just got fried ohh well at least ive got parts now. I wonder what the input is for the screen

Wait, wtf, you plugged your cellphone to the tablet and it got fried?!

No, it was plugged up to the charger I tore it down. Now I have a idea for the leftover parts. I've always wanted an android powered, touch screen head unit for my truck

[Q]Can Archos 70 use USB Mouse?

I've try with my CA-157 usb host cable to connect my usb Mouse, but the mouse show that have power but Archos seems nothing show up.
How can I test my mouse with Archos?
*my mouse is work on my PC.
Thats because the archos only can give a little bit of energy to usb host devices
Maybe you can test with an pc program how much energy your mouse need?

That program displays the USB device connected to a PC, but it doesn't show how much current the USB device is drawing, does it? I'm interested to know if there are PC programs to tell you how much current an USB device is drawing, as you said in your earlier reply :

If you plug the device into a windows PC (I'm on XP so apologies if this is not up to date) and look at the device manager/USB devices, one of the tabs on the properties sheet (power) will tell you how much current the device is drawing.
The USB mouse I have plugged in is drawing 100mA which is right on the limit for the A70. Of course you can always work through a powered hub but it's all extra cables!

Maybe you have the Usb Host Failure? Search here at forum
Yes, a USB mouse (and keyboard as well) did work on my A70s once I put it through a powered hub.
The specific one I used was a cheap Dtech DT-4012 which has an 700mA internal battery with a wimpy solar charger (but no jack for external power).
The keyboard works as expected and you will suddently get a conventional mouse pointer on the screen when the mouse is working. This of course is real handy when trying to use a tablet with an external display through the HDMI port.
Note that I could NOT get this to work with Belkin F5U404 powered hub or a very generic 7-port powered hub I bought some time ago that seems more interested in providing a flashing multicolored light show than being a powered hub. I'm thinking this might be because these hubs somehow don't tell the USB port on the A70s to switch from an "OTG" (client-mode) USB port to a "Host"-mode port. Anyone know how to manually switch modes (such as in poking something in /sys somewhere?). Something like this had to be done on a Nokia N810 (which I still have one), so maybe I'll check and see how it was done.
... i tested a while ago and it didn't real worked how i wanted it to work

[Q] adapter miniusb to usb

hi:
i think i will try to get hptp from ebay.
i see that it doesnt have usb for flash drive..
assuming that if connected to a dongle, it will read/write to flash drives,
which adapter should i search for.. mini male (for tp) > usb (flashdrive)?
thanx
I have read a thread on the usb host mode for the TP (can't remember which of the 8 forums I am on) that the micro usb port WILL support host mode BUT you will need a "Y" cable to provide power at the same time. Do a search for "host mode " on the TP forums and check it out. I have not attempted it so far as I have not found the correct "Y" cable mentioned in the thread.

There is fully functional USB Host support, you don't even need to do any SW modification, everything is supported out of the box with one caveat, you need external power.
Support for keyboard, mice, harddrives and cameras is fully built in the default WebOS software.
I guess HP planned to sell their own USB attachments, iPad-style.
The only thing you need is USB OTG cable. Like this: http://www.ebay.com/itm/New-micro-U...781644?pt=PDA_Accessories&hash=item19c7d49acc
Basically just search for "USB OTG cable" on ebay, costs about $3. And USB Y-cable. The only two things you need are OTG microUSB cable and USB Y cable to provide external power.
I am still looking into possibility of self-powered usb host mode, with all the support HP built in for it it almost sounds like a given there must be a way to enable it one way or another. Unfortunately chipset documentation is almost nonexistent.

What i've got: unusable pile of crap. The whole system can power up a mouse or gamepad, or external HDD (which is need to be powered from wall socket in addition to TP) but it's much worse with anything else: 16gb flash stick - lights up, but not enough power to read data, USB card reader don't even lights up. And situation with powering from PC USB (instead of ext. battery) is the same.
Anyway, even if the whole system would work, i doubt that you would take all those cables with you wherever you go, so it's useless.
i watched the russian vid..
hassle w/ capital H
little to zero hope of this gonna ever work
thanx for replies

Sony Branded PS3 Controller works wirelessly without root!

NOTE: If you have an OFF BRAND Controller ALL BETS ARE OFF. THIS WORKS, BUT ONLY WITH THE SONY BRANDED CONTROLLER
Is this weird, or has support for it crept in in the last few ICS Builds and I missed it? I am not much of a gamer, not by any standard, but I was impressed when I saw video of Games like Riptide and Shadowgun with a PS3 controller.
Only limitation was, they had it cabled and not wireless, but then everything I read while researching said I would need to be rooted and use Sixaxis from the Market if I wanted to pair it wirelessly. I took that at face value and moved on. THEN...
Tried my sones wired Xbox 360 controller, and it worked, mostly... Wanted a better experience and my own controller so tried 3 different off branded controllers, one was a Madcatz (Xbox360) and that worked a little, but not great, then tried 2 others one was a Power A or something like that, forget what the other was. Neither worked at all, Nothing...
So I gave in and got a nice, Bluer, Sony Branded DualShock 3 controller. Used a USB to Mini-USB cable I had laying around, and hooked 'er up. Played Riptide. Wee. Tried Shadowgun.. cool for about 90 seconds... Then I got frustrated when it wasn't easy enough for a 5 year old to play... like I said, not much for gaming. I like racing games quite a bit, and tried Need For Speed Hot Pursuit.. WHEE EE EE!!! kay, enough of that... Then I grabbed an N64 Emulator (actually a few, N64oid, SNESDroid and SuperGNES. Loaded up some old favorites. DiddyKong Racing. Super Smash Bros. etc.
Then I saw it, I was on the .13 build for the last few weeks, no major issues, just generally crappy battery life. But when I was testing some router settings for better throughput, when I went to turn on Bluetooth... whoa... Why does it show PLAYSTATION(R) 3 Controller among my BT devices? Figured it was a tease, no way I had a wireless connection without root.
But no, I went an got the controller, and as soon as I pressed the center button, like a SPLIT SECOND later, that entry went straight to the top of the list, and showed... CONNECTED. ???
Go to a game, and it was soon obvious. It just works. And works amazingly well. I suggest ANYONE that has a Sony Branded PS3 controller, and has not tried it repeat my steps... Just so we can prove this is not a fluke... Oh, and I flashed .14 today, and it still works... I don't care what changed, I am thrilled.
I may even become a serious Gamer! anyone for a real Gamers Hard Core game.. like, uh... what Angry Birds or somethin'?
Thanks. I can't wait to try this when I get home.

Yep. I hope it works as well for yo as it did for me.. Just cable it and play for a while first... The weirdest part? I never attempted to attch it via Bluetooth. Never even tried!
Heres another guy saying it works, but claims it works even with Bluetooth off (It doesn't - I HAD to try that, knhowing it was BS, but flipped BT back on an all good )
You can use a wireless Xbox controller with almost anything if you have the USB wireless microsoft receiver. I tried it today with SNESoid & N64oid. I am also not rooted and it works without any special app.
I thought it was common knowledge that you could connect a PS3 controller wirelessly without root if you had the dock, I'm pretty sure you can do it with the original TF too.

News to me. I had the TF101. And you needed it cabled to use a controller - Also, why on earth would you need the DOCK to connect WIRELESSLY? The only thing it ADDS is a USB port (And SD card which is meaningless) For that matter you can get the USB adapter that goes in the charging port to cable the controller to the Prime, if you can find one - I have one from my TF101 - Here is THE video used to demonstrate the PS3 Controller in use with Prime:
You sir are a genius...awesome!
@smarta$sphone. i may be wrong and sorry off i am but how did you have a USB to mini USB on the prime? where would the USB go? and the mini end would not fit either only micro but still confused because ps3 controller does not take USB takes that odd shaped crimped port... please advice?
And whoever said the controller will work wirelessly with dock? don't that defeat the purpose of wireless or is it to connect dock first to device to be able to use the controller wirelessly? sorry don't understand thanks
or you talking about plugging USB into the dock to begin with?
I know it works wireless (the controller) with the Sony Tablet S.

That "crimped port" is one of the most common smaller charge/data ports for older mobile tech and other things...
It's miniUSB. Just uses any ol' miniUSB to USB cable, and the dock has a USB port which is needed to sync the controller to the Prime...
I don't understand your mini/micro USB comment there, so no real comment on it...
*EDIT:
Right! I should have said it more clearly. Like the next poster says, you have to have the dock (or that adapter) to have a USB port on the Prime; all the tablet has is its proprietary charge/data port.
thanks
gotcha, lol didn't know that the crimped style was USB... so if i got that connection to a mini USB it will plug directly into the tablet or would i need mini to micro USB? worth four all the questions thanks btw
does the tablet have a mini or micro USB port?
You need either Asus Adapter or dock for USB

Yes, sorry for any confusion. I initially plugged the Dualshock 3 into the dock via a standard USB to Mini-USB cable. I also have the USB adapter that fits in the Tablets charging port, but I rarely use it - Once as an experiment I plugged the adapter into the charging port on the dock, hoping it would provide a second USB port. Logically it could have worked, but that was not the case.
You asked who said the controller would work wirelessly with the dock? Uhmmm Post #5 in THIS THREAD, the one directly before my comment, that I QUOTED in the comment?
And what ARE YOU talking about? No offense, but that "Odd shaped Crimped Port" is a MINI USB... Very common, and was used on more devices, phones, cheap cameras tablets etc, for a while until Micro USB took it's place for thinness. Look up "Mini-USB" in Google, then hit "Images" Very common...

The Tablet has NEITHER... The tablet ONLY has a proprietary charging port, but you can add THIS ADAPTER if you do not have the Dock. The adapter and the dock provide full sized USB, so you cable wood be USB (Full sized) to Mini (For the controller) Obviously you do not have a Prime, so why ask all of this?

It's your microHDMI port to have audio/video out to HDTV's and receivers.
sorry that was a typo..i meant micro HDMI not micro USB my bad... sorry for confusion and when i said something about post 5 i know who wrote it but was just talking about it in same thread was not directed directly at you but in general..
so aside from my confusing posts what i wanted to know is if they make mini usb to micro hdmi.. but i will Google it since i seem to be bothering folks.

Even if they did make that cable it would be quite useless with the prime. The tablet itself has no USB controller onboard. The adapter and the dock both have a USB host controller which allows the tablet to communicate with USB devices. HDMI is High Definition Media Interface, its not for hooking up I/O peripherals other than a monitor of some type.

Right!
Your (micro)HDMI is just audio/video, like more compact (and digital) old RCA cables.
The only way to transfer data over a hard line with the Prime (just the tablet, no keyboard dock) is through it's 40-pin proprietary port: be that through it's charging cable to a computer, or the linked adapter to some other USB device.
Keyboard dock needed?
Sorry I'm an idiot, but do you have to have a keyboard dock to user PS3 wireless controller?
Have someone tried connecting two PS3 controllers at the same time? One with bluetooth and the other one trough the USB connector. Would have been nice if you can play co-op games on the SNES. (Contra!)

Touchpad USB OTG Compatibility List

Thanks to a recent video by reverendkjr on Youtube, we now have a confirmed USB OTG method for CM9.
http://www.youtube.com/watch?v=Nc7tlPwFQpg
This has lots of potential and since I did not see much talk about it here, I decided to create a thread with what you need to buy listed in reverendkjr's video and what works. I would recommend only buying from Amazon Fulfilled sellers as they are backed by Amazon's return policy. All 3 items only cost a little over $10.
OTG Cable:
http://www.amazon.com/gp/product/B005QX7KYU
USB Y Cable:
http://www.amazon.com/gp/product/B0041CFFBM
2AA Battery Powered Portable USB Power Supply:
http://www.amazon.com/gp/product/B003M9Z5F6
(Added September 7th)
OTG Cable With Female MicroUSB (Allows you to use any microUSB charger as the power supply)
http://www.ebay.com/itm/130740524313?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649
OTG Cable With Male Full Size USB (Allows you to use any power supply with regular USB port)
http://www.ebay.com/itm/Micro-USB-H...i9100-S3-i9300-i9220-i9250-XOOM-/140825132367
You can use whatever source of USB power you want including a wall charger, but I bought the 2AA battery powered supply above and can confirm it works.
Compatibility List:
-Multiple USB devices will work if you use a USB hub. A non-powered one works fine for me since you will already have a separate power source.
-USB keyboards and mice work fine including all basic functions like scroll wheel on the mouse, num and caps lock on the keyboard.
-FAT32 formatted flash drives will mount by default under "/mnt/usbdisk".
(Added September 7th)
-If you want to mount NTFS drives or multiple flash drives, download Drive Mount. This software will mount drives under "/mnt/sda1", "/mnt/sdb1", etc. I can confirm it works for multiple drives and NTFS/FAT32. It was removed from Google Play so the apk has been posted. If anybody has had success with other NTFS mounting software please post your results.
(Added April 6th)
-I tried a Rosewill USB SATA/IDE externally powered hard drive reader and was able to mount a 400GB SATA 3.5" HDD using Drive Mount. Just to see what would happen I tried a SATA DVD drive but Android doesn't recognize it and probably doesn't even support the CD/DVD file system.
(Added April 7th)
-USB card readers will work, but I've had mixed results.
USB Device Info:
If you want to diagnose items and see some info about what the Touchpad is detecting, download USB Device Info free from Google Play. Everything shows up under the Linux tab. This shows some useful info about devices including current draw, device identification, etc. I tested it with a USB hub and a few flash drives and it successfully showed entries for the hub and the flash drives. It wont tell you if Android has drivers for the device, but merely IDs the device(s) confirming the connection if working.
(Added Dec 9th)
A plugged in USB OTG adapter will show up as "Qualcomm On-Chip EHCI Host Controller" under the Linux tab regardless of whether or not power is present. This is a good way to see if you have a working OTG adapter.
Flash Drive Unmounting Issues:
Flash drives are called an SD Card when mounted. There is no option to unmount a flash drive unless you use Drive Mount, so if you notice SD card removal error messages they are referring to your flash drive and not the Touchpad's internal memory partition that is mounted as /sdcard.
When a flash drive is removed or powered off without being unmounted, its common to get a "android.process.media" force close, just tap OK.
Charging:
You will not be able to charge via micro USB while using OTG even if your power source has enough current. You can charge via the Touchstone just fine. Knowing this, you can set up a really nice docking station by using the Touchstone as a stand/charger and then using the microUSB slot for peripherals like a USB keyboard and mouse connected to a hub with spare ports for flash drives, etc.
(Added September 7th)
Insufficient Available Bus Power Fix:
If you get this error, I haven't yet, some users have had success using this app posted on Rootzwiki.
I didn't feel like buying anything and already had some things laying around so I modified an Adafruit MintyBoost to accept a device via usb, add power, and continue on down the line...
Really all I did was solder a usb cable onto the female USB port on the MintyBoost, drill a hole on the other side of the tin and feed it out. The card reader conveniently fits inside of the mint tin so it's a pretty compact package.
The only down side I've noticed is that it also charges the TouchPad (the batteries will die quicker) and continues to send power to the card reader after the OTG cable has been unplugged from the TouchPad.
Excuse the crappy pic. I really don't feel like taking a better one.
I could never get the OTG cable to charge the Touchpad, I always thought when the Touchpad sensed OTG (grounding on pin 4) it refused to take power. You can disconnect the +5v Vcc to the Touchpad (red wire) on your OTG cable and OTG devices will still work.

I came to the same conclusion some days ago ,touch pad can't be charged using org cable,needs a regular micro USB cable and the barrel AC charger.I did many tests but having otg devices working and really charge at the same time its not possible,it seems like charging but its not.
Today I accidentally found this http://direct.sanwa.co.jp/ItemPage/400-GADR002W that by first look it could be awesome...
Edit:a mini review in english http://www.gadget.pdamu.com/2012/03...r-dock-station-for-android-smartphone-tablet/
says that it can be also powered be micro usb charger....

If its provides its own 5v power it would likely work, but I don't really see anywhere for an external power connection and it looks too small to house a battery.

For whatever reason, when I tried that the card reader wouldn't initialize. Once I connected the +5v from the OTG it'd light right up...
After it lit up I could disconnect the +5v and it'd stop the "charging" notification on the touchpad and keep working.

Then it should work fine as the Touchpad uses a standard OTG pinout, it just doesn't provide power so if it has a way to provide power to devices than I see no reason why it wouldn't work.
quick question that i didn't see answered above :S can i use the otg cable adapter without another power source (like can touchpad power it?)? Saw it asked above but didn't see anyone saying that the power source is required :S
kind of want to plug a usb flash drive into touchpad so I can type documents when I'm on the go and switch to computer. don't want to carry another power source either :S

No, the Touchpad doesn't provide any power for OTG devices which is why you need to supply it power. The cheap USB charger I linked to in the original post will work fine for a portable power supply if you don't want to build something yourself.
And it also appears you can't just plug the other USB into the wall?

If its provides its own 5v power it would likely work, but I don't really see anywhere for an external power connection and it looks too small to house a battery.

And it also appears you can't just plug the other USB into the wall?

So, we can't just plug it into a wall for power? I have to buy a battery powered unit or use a powered hub?

Nice and cheap and the best part it works.
USB Hub works...sort of.
I tried this with a cheap USB hub I bought. I had bought it for my laptop and made sure it had it's own power supply to keep the load off my laptop, so I thought it would be perfect for this. Nice try though.
Turns out it needs 5V from the host to activate as well as the additional external power supply. Just fired it up with my TouchPad connected via a Y-Cable and my Laptop providing the 5V to fire it up. Works like a charm.
As yet to find out if it works with my travel charger providing the 5V and no external power supply plugged in, and how many devices I can hook up. It's got 7 ports so I suppose the supply might be useful then, but do I really need to hook up that many devices? Otherwise...pointless. Back to the drawing board I go.

This would be really handy and it's a much more elegant solution than a y cable and external power source.
Too bad it seems like we won't be able to get one easily.
Am i missing something here or can i use my 3.5" external HDD (with a power supply) to provide power to my External so i dont have to plug the cable into a USB hub?

You should, I did this on my Touchpad running CM7. Haven't tried since going to CM9.

[Q] MHL & OTG simultaneously on Xperia Z Ultra?

I bought a USB hub which sports an MHL and OTG (See attached) .
On my xperia z ultra the MHL works fine but when I plug the airmouse into the OTG the phone doesn't detect the mouse.
I tried to unplug the MHL (removed HDMI cable) and use only the OTG feature but the phone doesn't detect the mouse. The phone doesn't detect any USB storage device as well.
The MHL and OTG feature is a built-in option in Xperia Z Ultra so it should output as MHL and and detect airmouse at the same time, but it doesn't work.
Can anyone please help me how to get this done?
Awaiting for replies anxiously

I would honestly go with chromecast, it's your best bet to use the mouse as well.

The chromecast will not support the airmouse that I have. There is a small usb donlge for the mouse which needs to be connected to chromecast. I see there is no option to plug a USB device into chromecast, right?

I think he's suggesting that you connect your mouse to the phone and then cast the phone screen to the Chromecast.

I already mentioned that the airmouse is not detected by the phone; if it was, the issue will be solved because the MHL already working fine and output to big screen tv is fine.
My questions are:
a. Whether it is possible to use MHL and OTG at the same time?
b. My phone xperia z ultra is not detecting any usb devices such as pen drives, regular pc mouse or the airmouse. How do I get that to work?
Further update: I was able to get the OTG working and the phone detected the airmouse, however I could only use either of the MHL or OTG but not together. Any ides how to get the MHL and OTG work together?
How'd you get the otg to work? I bought 2 of them. But my Xperia Z ultra isn't detecting it.

Its easy. First of all OTG doesn't require any additional power to be connected to the HUB, you need to remove that. Second, plug in hub into the phone, then plug the USB device into the OTG USB slot of the HUB, then keep pressing the switch on button until it becomes "Blue". Please make sure you don't have any external power connected to the adapter at this point.
No I was talking about otg to the phone. I had no issues with Samsung but my phone doesn't detect the cord when I plug otg in it says USB connected, but when I hooked up the ps3 controller it had issues of not being recognized.
You can't use both MHL and USB OTG features at the same time because Sony Xperia devices (including the Z ultra) use 5 pins MHL connectors as opposed to Samsung devices (since the Galaxy S3) that use (not standard) 11 pins connectors for this very purpose (which is why most MHL cables require the use of an adapter on these)
