is there any way to built support (physically) for using USB OTG mounting and charging at the same time, say if im on a train and i have a portable charger... and want to watch a HD movie, i still want my charge
ive searched for micro usb HUBS but dont seem to see any, and above that, i dont know how i would get power to the phone from it
EDIT: also is there a way to safely remove usb without just pulling it from the phone? im talking about USB OTG mounting... using resurrection remix 1.4 w/ siyah3.1rc6 =]
you could try using a T cable , its a cable the has an input for power and an output in to the phone.

Good Morning
When I want to connect my droid X phone to my laptop, the cable is usb on one end and micro usb on the other end. So can I use that on my Sony S also to connect to the laptop? or are there different wires inside the cable or something so that I cannot use it, different wattage or amperage or whatever??
As always I am technically challenged LOL
Sandy
The Sony Tablet S uses the standard Micro-USB cable so you'll be able to connect to your laptop with no problems.
It will work for both, given the chip( Mini USB) is the same for both. The cable just carries the current. It is the charger portion that puts out the specific voltages. You are good to go as long as the mini USB fits

Really? This works?
Uh oh. I've tried hooking up my tablet to the PC with a standard micro usb cable. And also with the sony converter that makes it a normal sized USB port and a double ended USB cable. Both of these didn't do anything for me. I've just been transferring files to/from it with the sony converter and a jump drive.
Anyways, let me know if everyone else is normally hooking the tablet to a PC or if you guys are just assuming. Thanks

You should only need the one cable.. The cable I use for my HTC Desire HD works on the tablet and the same with the cable for the Galaxy S II as they are the same kind of cable.
Just connect micro USB, from tablet to PC and it works

Same here. I plug it in with a cheap USB <-> Micro-USB cable and it recognises it instantly and I can copy stuff to and from without even having to mount the storage manually.
Weird!! I tried plugging it in with my normal phone's micro usb cable when I first bought it and nothing happened. I tried again last night and nothing happened.
I just read all your posts about how it will work and I tried again, and my computer recognized it this time.

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:

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.

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?

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?

However, is there any way possible to charge your phone WHILE using the OTG adapter? They both use the 1 micro port on my phone, but I need to find a way to charge the phone while using the OTG adapter.....perhaps a micro USB splitter-type adapter?????
I was actually wondering about this myself, though I don't think a splitter-type cable would work. I'm wondering if the power connection is on separate pins than the data, though...if they don't share space then I'd think it would be possible in some fashion.

A similar problem is showing up regarding using the mhl port to output to hdmi. Though the original information indicated that the power cable was supposed to charge the phone it seems it does not on the first version (super DUMB).
I have read though that the newer version of the mhl port is 10 (I think) pins rather than the 5 of the original. The newer port DOES allow charging while output is in operation.
I suspect this will also allow an OTG cable that charges while in use.
I am not so sure about the mhl idea anymore. Only one port for everything is ok if it has enough pins/bandwidth to have a breakout box that would allow an external usb drive to be read while hdmi is being output to a screen and power is supplied to the phone. As it is now with only one-at-a-time it isn't very inspiring as the phones get closer to the power of laptops.
What would be really neat would be a box with wi-fi, and the output to hdmi and usb ports as well. A wireless breakout box. Then the charger could be over by the phone which is near the user.

I think this thread could solve your problem.
Oh... I found a useful diagram here.
Hi, i want to use a USB OTG cable and use a USB hub on it so i can use 1 port to charge the s3 and the other a wired ps3 controller.
Can the s3 charge this way?
yws, but it's freaking slow.
Yes you can, and you can also charging iphones on it
Sent from my GT-I9300
i mean that the otg cable will be on the s3 and i want to charge the s3 with a usb cable on the hub, not that i want to charge a s3 by conecting it usb cable on the hub.
In other words by using a usb hub in the s3 usb on the cable can i charge it on 1 port and the other port use a ps3 controller wired?
I want to use the ps3 controller on the s3 wired but charging the s3 at the same time.
I didnt understand.. Sorry

No clue but I'm also curious about this. In guessing you don't already have the hub otherwise you'd just have tried it.

It works. I'm doing exactly that right now.
USB hub plugged into the phone, keyboard + mouse + charger plugged into the hub. Phone shows AC charging status.
This has only happened once but: it didn't charge until I restarted my phone.

If it really works its great work by Samsung as so far I haven't been able to get it work the same way on my SGS2.
Ok so today i got my usb otg adapter and im on buttertoast 14.4,i have enabled otg on kernel tuner and when i check the mode file with connected adapter it shows -host ,and after disconnect shows -none,so it should be working.

Does your adapter allow for power to be supplied to the device? What type of USB peripheral are you trying to connect?
There's a lot of OTG related information available in this thread.
ramjet73
I think that you need to have external power source. I tried with only OTG adapter but it havent worked. But when i connected external power source (USB) It worked like a charm.
No power supply,its a simple otg cable and what I'm trying to connect is simple 2gig flash drive. And I think I looked through that thread. So you think I need to modify my cable ,is it the only way?

You have to supply power either from a powered USB hub or an OTG adapter like this one that allows you to use your HTC charger in order to use flash drives and portable hard drives, or any other USB peripheral that requires power.
ramjet73
Well with the power supply it looses its portability. :/
Guess I will have to solder an otg cable with attached battery to it ,or even put it all in a little box so there isn't wires everywhere.Cause I saw a video on youtube with a guy who had attached another HTC battery to the adapter.
So basically its explained as EVO doesn't give out enough power to run the device?
