Hi! all. need to find out if its possible to use a USB hub to attach 2 or 3 thumbdrive all at once so that i can copy & paste files from one thumbdrive to another.
maybe a powered hub. I just tested a non-powered hub and the minute i plugged a usb 4GB flash drive in I got that error about a "high powered USB device".

I confirm, powered hub is working well.
Yeah, I have a 3 port USB dock with SD Card + micro reader for the Tab family. I think you need those specially-made docks for use with the Tab family. Normal USB ports won't work due to the different 30-pin cable that Samsung uses.
Link Please
I have seen multiple adaptors but they only work for image files and certainly do not have multiple USB inputs.
Could you please supply a link for the accessory you describe or, if that is not possible, the name of the device and/or the manufacturer.
Thanks

Sounds great! From where you purchased that 3 port USB dock? Can you pass me the link showing its photograph and place to buy?
Thanks buddy!

Hello I got a USB gender change: A-Female to A-Female so that i could connect a self powered USB Hub to my Archos.
So far i have connected a self power Hard Disk directly into my Archos 70.
Didn't pick it up.
A mouse in the USB Hub.
Didn't pick it up.
A pen drive directly.
Didn't pick it up.
Is the Archos 70 locked down or does the USB Micro B connector they have on the Archos 70 work different?
I thought USB was a universal connector!
... one thing you have to realize is the device needs drivers to work those devices. you just cannot flip flop the connector and expect everything to work. tipically unless the device has a INPUT port which is a standard usb port not a micro or mini 5 or an old 1.1 usb connector it wont work.
Alot of those hongkong micro a to b converters are rubbish.
The nokia has been reported to work.
You need a USB "HOST" Cable, it contains a chip that puts your devices on "master" mode.
The Nokia and Archos one work, for the others don't expect them to work at all if they do not mention to be USB "HOST" cables !
BTW, the feedback is not very good, seems that it can deliver only 200mA, so if you want to plug an external disk drive, make sure you have a power supply on it before
Also some USB keys need more than 200mA so they won't mount at all :/
I found this: http://www.kjell.com/content/templa...9&path=97000000,119000000,149500000,151500000
Translation: Used by for example mobile phones with USB host (it's own built in USB controller).
Is the USB "HOST" Cable the same as this? http://en.wikipedia.org/wiki/USB_On-The-Go

That cable doesn't look correct.
[correction - that cable at kjell looks correct for hooking two USB On-The-Go devices together. So if you wanted to hook your Archos to another Archos or to a blackberry.]
Look for a micro usb Nokia n810 host cable. Or "Micro USB Host OTG". They seem widely available in the us on eBay
Usually they have the micro USB male connector and a full size female connector on the other. Be careful because some are mini USB, you want micro USB
Look on the us eBay for a picture.
Here is a pretty good picture also - http://www.dealextreme.com/details.dx/sku.51045 several people have confirmed this one works.
Yeah, the connector is obviously wrong on that one. I was mostly curios about whether this USB HOST cable was the same as an OTG.
That's the only cable of OTG type that I've seen in any retail store in Sweden (although I haven't been looking for it until now), so I was thinking of maybe getting it in the store and then get an adapter for the connector. But since there's a special pinning on these cables (as I understand from the Wikipedia article) maybe that doesn't work?
I'll probably go for the Nokia cable anyway, just to be sure, should be able to find it in a retail store somewhere...

this works fine on my 32IT. I can use my microSD adapter, camera, powered hard drive, multi-card reader with SD cards and USB mouse. Other people have said they can't get USB host to work at all, even with this cable, but it works for me.
USB mouse works ok.
But it`s not enought power for 3G USB dongles.... Печалька.

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.

well i got hptp today..
the ebay link USB OTG cable for was great..
the y cable search was confusing:: i do not know which kind to look for plus.. i dont see how to use this thing.. how does it get power.. i spose the USB OTG cable plugs into one of the "y" but im lost really...
i appreciate all responses..

External battery with USB: http://www.dealextreme.com/p/2400ma...a-cable-for-htc-desire-g5-samsung-i9000-57905
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
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 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...

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?

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.

If I connect the 4GB pendrive it works normal, when connecting external HD, it only lights up but does nothing on the android.
I installed MountStikc (app) and it did not work, could someone tell me what the problem is?
It's probably a power issue. These units don't seem to output a lot of power over the USB ports. I had the issue where my USB HDDs didn't work on the unit but pendirves did. I got one of those USB cables that let you get power from 2 separate ports and that did the trick for me.

You'd have to use the USB ports on the back, if it has them...or a way to get power to it separately from the USB, if the drive has a separate power input, but that may be more trouble than its worth.

Do you have a native firmware MIUI?
You can experiment, first connect the charging going to the hub, and then the periphery of the USB flash drive or keyboard and mouse..
and then vice versa, first the periphery and then the power to the hub
on my tablet with micro us it mattered... Can you try different variants
I guess you will need something like the one in the link below that supports USB Power Delivery.
https://www.aliexpress.com/item/USB...469.html?spm=a2g0s.9042311.0.0.3b144c4dDoroZN
It is mainly for Macbooks but it is compatible (according to the sellers) with most Smartphones and Tablets that use USB Type-C.
I just ordered one for a project so I'll know in several weeks (when it arrives from China) if it works with the Mi Pad 4.
Update: I've just checked the hub you used and it is also with USB Power Delivery... oh well let's see if I'll get lucky or...
anyone have success with this? i have a few adapters and hubs that work with everything else but not the pad 4.
