[Q] USB OTG: usb1 found, cannot use keyboard

Hello,
I have a USB OTG cable and dell keyboard that I have tested and work in OTG mode on a Nexus 7, however i cannot get them to function with my HP Touchpad 32gb, running CM9 2.6.35, built on Sun Oct 28.
The device recognizes when I plug in anything via USB, but only as a generic Linux USB hub, and not as any particular device. Are there any steps to take to debug this? Has anyone had experience with this type of an issue?
Thanks for your help,
Cory

I don't know if this is the issue, but I know the touchpad doesn't support OTG like the the Nexus does. I think you need a Y-adapter + OTG to provide power since the micro usb port doesn't give any power to the device you connect. Someone correct me if I'm wrong though.

Apparently even a powered USB requires a powered Y cable to be properly recognized. I hacked together a quick Y cable manually, by splicing in another USB cable's power and ground (Red and black) to the respective locations on a female USB cable. Works as expected.
I am now communicating with an Arduino over Serial
Thanks!

Read this thread, should give you all the info you need:

Basically the Touchpad has OTG but it provides no power.

Agreed. I think people just are not stating reality regarding the ability to charge and use OTG Hosting to USB devices at the same time.
My goal here has been to attach a flash drive with video/audio media and play & charge on long flights. It looks like play, charge are mutually exclusive on my beloved TouchPad.
I've asked for the specific confirmation of this from this YouTube but have never had the poster reply:

There are devices out there that have very advanced micro USB device implementations. Sadly the HP is only superficially supportive.
I for one cannot wait to get my SGN2 smart dock which offers:

USB OTG on stock rom issue.

Bought 2 USB OTG cable a few days ago but I've been unable to get it work. The moment I plug it into my HTC One, a "Unable to charge device. Please use the supported charger" error. 2 different USB OTG cables, same error. Bought at different times after I couldnt get the first cable to work.

I'm having the exact same issue... I have 2 cables which both work with my Nexus 7 without any problems what's so ever. Does anyone know if there is an "official" cable from HTC or is there some kind cable standard which has to be adhered to, so it works?

I just got a cheap usb otg cable from eBay, works fine for me. What size drives are you trying to mount?

The Stock Kernel doesnt support NTFS or ExFat... u have to format to FAT32 to get otg to work...
Maybe there will be a kernel with ntfs or exfat support someday...

There can be problem with your pen drive. Cause i had lived the same problem. My sd card works in pc but not in phone. I tried using my mouse or another disc with OTG cable and they worked.

The stock HTC kernel has a whitelist that module blocks OTG access when a certain limit is reached like required voltage by the accessory in order to work. Custom kernel now has this disabled so you might want to check that if you want. But if you prefer stock kernel I suggest you guys look for low powered USB drives instead. Cable alone won't have any issues at all with compatibility.
The main issues are the filesystem type & the electrical current required by the USB drive or any device you want to use for OTG.
The charger notification is a bug and might get fixed soon by HTC but it won't have any effects on OTG itself. It's just the kernel mistakenly identify the OTG device as a charging mechanism.

one from amazon, and 2 from ebay, worked great on my HTC ONE S... and samsung galaxy s3, on my HTC ONE, the freeze up, lock up, i dont even try it anymore.
yeh, i also get the charging thing error...
i believe the one i bought also said for google nexus... i use 32gb...

How does that 4gb stick work is that like a usb flash drive you can use with the One?

Without any usb thumbdrives attached to the otg cable, the moment I connect the otg to my One, the error pops up. Later connecting the thumb drive to the cable does nothing. Es file explorer does not detect nor does mount usb drive light up (remains greyed out).
Tried connecting the usb drive first and then connecting both to my phone and does detect either. So yeah, I guess might have to buy another usb drive ?

i had the same problem, but....
I was very dissapointed because my htc one could not find the otg usb! I started deleting almost all downloaded software from my device and cleared cash! Then restarted my phone and... Voila! It works! To be honest, i didn't find out the problem, but it works!

[Q] Connect USB Device to Nook HD+

So I'm currently running Carbon ROM B6 on my Nook HD+. I was hoping to connect a keyboard via USB to the Nook HD+. In order to do that, I figure I'd have to get a female to female USB adapter, and plug in the keyboard on one side, and the Nook in the other. Before I buy a female to female USB adapter, I figured I'd ask if this would even work. To take it one step further, could this work with any USB device at all, such as a mouse, flash drive, PC Xbox controller, etc?

It works on CM10. I am not sure if Carbon has that feature but USB adapter is only a couple of dollars.

Yup, worked fine. I tested a keyboard and a mouse and both worked perfectly. I also tested an external HDD (Seagate Backup Plus) and was able to get that working with USB host mode turned on.

I don't know, that depends on the electrical current it needs and reports to the host controller.
If a device is over that curent, the host controller will turn it off.

So if I buy a female-female adapter and plug in a usb stick I should to be to access the content i.e Movies?

Hi
I've downloaded this and tried it but my Nook HD+ doesn't seem to do anything different after I have enabled the program and plugged in a usb stick. I'm running a nightly build of CM11 if that makes any difference.

Then your USB stick needs a too high current, try it with an actively powered USB hub.

Check out http://www.zen24223.zen.co.uk/TPUSBUMount6.apk
The instructions are here http://rootzwiki.com/topic/33033-otg-usb-insufficient-available-bus-toolthingy/
plug in your usb device and "press fix insufficient power req" button. works like a charm for my ps3 controller, no usb hub in between the controller and nook required.

As stated, the R1 does not support OTG. You can try a powered OTG hub, but your not going to get enough power from the USB port alone on the R1.

Hi Kal250,
Thanks for your reply. Please excuse my ignorance. What is a powered otg hub?
Can you please give an amazon link as a product example?

I can't verify that this will work, there was only one user who reported success using an adapter, though I can no longer find the post, anyhow you can give this a try, you will have to supply power with a charger cable, but I make no guarantee as to if it will work. BLUs official statement is no support for OTG. I'm not responsible if you damage your device(s)!!

I'll try it this weekend.

Holy crap, can confirm.
I first tried using this powered hub, as well as a powered usb otg cord (similar to this one), it read my generic usb stick, as well as a 500gb HD (well, sorta, it saw it but can't read ext4).. Then I tried just the otg cord, powered, and it worked. As long as it was getting external power, it seemed to work just fine.
Bare in mind, it "NEEDS" the powered OTG cord, running it without having a micro usb hooked up to power in and it didn't work at all, at least for me. Though you can run the hub without power, don't know why this is, but it was how it was acting.
Non drive testing:
It also sorta saw my Logitech F310. In that it pops up that it is disconnecting, but never shows up while connected (with gba.emu). A 360 controller did nothing.
Mouse and Keyboard worked just fine.
USB Audio seemed to not work, at least with my crappy Griffin iMic (think it is an apple device, I got it at goodwil). I also tried a Logitech usb speaker (not sure what model). No audio came though, thought the buttons worked (play/stop/volume/skip). All this with "Disable USB audio routing" not on (as well as on, just in case i was misreading it).
I also have a Pinnacle Systems AV to USB2 (old school rca video cables to usb) adapter I "could" check, however I know of no android app that can take that in. I do know it works with linux by default, ala V4L2, but android is a mystery. It does light up, but other then that no idea, looking through dmesg was a bust for me at least. Eh, nitch item anyways, doubt much here would use it.
Can't think of anything else to test at the moment, but I hope this helps you guys out a bit.

Tried the powered OTG cable and was able to mount a USB flash drive. I did not have to root my R1 HD to get this to work. The mounted drive did not show in ES Explorer or in Solid Explorer. But I can go to Settings -> Storage & USB and click on the mounted drive. That puts me in the system file explorer and I can copy files. (Do choose "Show SD Card" in the menu. Otherwise there are not many places to copy to.)
---------- Post added at 11:49 PM ---------- Previous post was at 11:20 PM ----------
Following up: of course you have supply power to the microUSB port of the powered OTG cable. I tried supplying power from an AC adapter and from an external battery both worked.
Another note: to copy files from the USB flash drive to internal SD or external SD, click on the USB Drive (in Settings->Storage & USB) first, select some files. Then, navigate to the place where you want the copy. If you want to copy to the USB drive, then click on the internal or external SD card (in Settings->Storage & USB) and do the same thing.

I bought a Blu R1 specifically to use in a pair of Gear-like VR goggles, as an FPV headset for quadcopter flight. I was hoping to wire (solder) a wireless receiver to a USB UVC stick, run Go FPV (split-screen Cardboard-like vid player), and power all with a 10k mAh power bank battery.
I'm hoping the UVC not working is just a case of a missing driver. Can you (moshiach101) load a webcam app from PlayStore and see if that installs drivers?

OK. I tried it with a USB wall-mount charger, USB-C micro in a brand new power OTG cable, with a Logitech V-U0007 webcam which was shown to work on a PC.
No dice. I conclude the Blu R1 HD does not support UVC via the USB port.
(and the phone is completely useless to me as I have a good phone and Sprint plan for the family already...)

Is there a way to add the UVC driver to the phone?
Is it part of the ROM, kernel?

It should be added by adding an app which needs it.
The UVC setup works with my HTC One M7. Not with the Blu, so I think this is a HW/FW limitation.

No dice (I just tried). Pretty sure it's an MTK processor, which doesn't do OTG, and probably why it's cheap enough to sell at this pricepoint.

Use a powered hub I have tried and it works for most devices (keyboards, mice, and USB drives), but for other devices such as an arduino, which is what I needed, use USB Host Diagnostics to install a patch.

Of course it works, you can play movies directly from the USB flash drive. You will need to supply power to the USB drive, connected by wire or using a Power Bank.

Is a Micro USB Port, is the same as your charger. The one that you connect to your Tablet. Search and do some reading on how it works, is very simple but you have to understand how all comes together, there is information on this site also.
Once you have Android install on your tablet, it works the same as others Android or Tablet Devices.

I finally got a OTG Micro USB straight cable, usb on one end and micro on the other, try it out and nothing happens, is there a setting with the tablet that needs to be turn on or off ? thanks

I don't see nothing since nothing happens once I connect it, though if I use the cable to connect to my computer I am able to see the tablet internal drive, but not to a flash drive from tablet to flash . This is why I was asking what's exact cable type for this tablet port . I'm thinking it isn't the correct one . There so many different sizes out there. Thanks for your suggestion, much appreciated

I sent you the link to Amazon of the OTG.

The HP touchpad or old devices do not offer power to the micro usb port, you need a Y adapter one to supply power to the USB flash drive and the other one for data.
That is why I said, do some research to understand the connection, which it clearly shows on the Amazon product.

Oh ok now I got you it also needs power to make it work, the tablet alone isn't good enough . See, I was hoping just a simple connector going into the tablet Micro and have on the other end usb female connector were by I could plug in a flash stick without power needed . Thanks for all your help

That will work with devices that allow power out from the charging port. The work around for old devices is the Y connector, with the connector I posted you can use a USB Keyboard, a USB mouse and a USB flash drive all at once, turning a tablet into a regular desktop PC. Like I posted your ROM will work and you can play movies directly from the USB drive with no loss in performance, with only your basic ROM nothing else is need it.
You are very welcome and have fun!

Yeah, those devises sound really good . I might just get one for that fact alone .... Though, it isn't really what I needed
