Galaxy tab p1000 and USB Mouse

Hi guys.. i've searched around how to make works usb host on our p1000.. i've tryed several roms and now i've cyanogenmod 9.1.0 since it support usb host and it works with Y cable!
now.. i'm using a self powered usb HUB.. connected to tablet through an usb female to female adaptor and official Samsung data cable.
so.. i've downloaded "Usb Host Controller" app, under "setting" tab i've selected "usb host mode" and now under "USB" tab i can see 2 devices ("1-1 USB2.0 Hub" and "1-1.4 USB2.0 Hub"). When i plug in an usb Stick (2gb) i'm able to mount it and browse through File manager with no issue.. but when i plug on hub an usb mouse.. tablet doesn't recognize it in any way! the mouse optical light turn on and turn off after a few second.. i've tried with two different usb mouse without success!
Any suggestion?

Hi sir. Ive been searching with this topic for so long. Im glad that you able to activate usb otg on p1000. May I ask which specific rom and kernel you used. May I have your screenshot of "About Phone" at settings. Thank in advance.

Hi.. i'm using official CyanogenMod 9.1 Stable ICS with kernel inside.. nothing special to do.. just download "USB Host Controller".. switch to host mode.. then plug your selfpowered usb hub or an Y-Cable with a power connection, since our tab doesn't provide enough energy from 30-pin port! but only USB Stick work for me.. nothing to do with other devices like mouse or keyboard.. for screenshot i can post it tomorrow!:good:

Hi, are you just using the standard samsung cable? AFAIK, usb otg cable must be used. Anyway I will wait for the screenshot and if possible a photo of your setup. Thanks

Greetings from the Philippines

Which exact version are you using to use OTG properly? I tried "sgt7-10.1-20130224-HumberOS-p1" but couldnt use mouse or anything. BTW I am using a Connection Kit with USB and card readers as a OTG device.
Thanks in advance.

Do not use usb connection kit. Just use the standard charging/data cable, y cable, 2 usb gender changer and the tab's charger.

Do not use usb otg cable as well. Y cable usually comes as accessory when you buy portable hdd.
Kindly see this post.

First of all thank you for your answers. Is this the configuration then:
1 Y cable (2 male, 1 female), 1 gender changer (2 female inputs), 1 tablet charger cable (1 30pin input, 1 male USB)
I guess that I should connect 1 male input of Y cable to tablet charger, the other male to gender changer. The remaining input of the gender changer will be connected to Tablet with its charger cable. Female input of the Y cable is left for mouse, USB memory, etc... If this is a true set up, could you please tell me what exact version of Android, kernel, etc you are using. The link of the ROM (CM9, CM10, etc) will be very appreciated.
Thanks again.

Hello @nogo8888
i've read your previous posts that you have experienced using USB OTG with mouse and keyboard functional on your Tab?
I own P-1000 either and already installed the latest ROM from HumberOS (that's the 06-2013 update) and trying to mount my devices such as keyboard and USB mouse, with USB Host Controller (by sztupy) but i have no result.
if you don't mind please kindly help.
Thanks for advance, greetings from Indonesia

hi
the best way for mouse and keyboard use the Bluetooth mouse and keyboard

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!

USB OTG, max. size for USB-Stick

Just a question. After rooting my Tab S2 9.7 I expected to be able to use USB Otg. And though it works with smaller USB-Sticks, it seems I cant get it working with a 128GB Stick. The stick worked flawlessly on a Tab S. I did install a custom rom on the Tab S, the Tab S2 is just rooted, and running stock 5.0.2.
Any thoughts, ideas?

Anyone has thoughts about this?

I did root mine, it's running in Marshmallow and I have the same prob, doesn't recognise 128gb stick but recognise the wd 500gb passport drive via otg cable fine.

Verify the format
Pay attention, it seems that the O.S. cannot use NTFS formatted keys...

I have it working on a WD 500G / NTFS external hard disk & not working on WD 2 TB / NTFS external hard disk
It must be size limitation

Nope, the s2 Tab cannot read NTFS natively (6.0.1)! You'd need special drivers to make that work.

Hello, how do I get to connect a USB device (flash drive/HDD/microSD) to my Galaxy Tab S2 anyway?? I just ordered a OTG USB to microUSB cable this week, and although physically I can connect a flash drive to my S2 this way, no drive shows up in my S2. I did make sure my drive is FAT32. Is there a particular brand of cable I should buy?

Did you check the file manager?

I have always had mixed results with my Android devices - some OTG cables work, some don't. Got this in January and it works fine with my unrooted 8" S2 (T713):
https://www.amazon.com/gp/product/B00N9S9Z0G
I generally use exFAT for my connected drives. Yesterday, by using a Y-cable with power supplied by a battery pack I connected an exFAT Western Digital 4TB My Passport drive to my S2 (drive sucks too much power to be used without separate power supply).

Blu r1 hd - OTG not detected even after rooting

Hi,
I just rooted my blu r1 hd and confirmed it by opening my #supersu app. I have root access. But I still am unable to make my phone detect my otg usb. I tried usb otg helper - but that doesnt seem to help. I tried stickmount and it doesnt work.
Can someone please help?
Thanks so much

Out of Box the R1 doesn't support OTG, there was a report of someone making it work with a powered hub. But BLU states no OTG.

Used other checker
Hi,
Mi used otg checker and it confirms that my rooted device supports otg. It did not say that before rooting. But still my device does not recognize otg.
Please help.
Thanks

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?
Your help is much appreciated. I understand that you are saying that it may/may not work. But I want to give it a try.
Thanks so much

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 got OTG to work with a powered OTG cable but I couldn't get UVC to work

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.

Try OTG Patch or similar from playstore

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.

Seagate Expansion HD (portable HD) not working.

Dear XDA peeps,
You guys helped me in the past when I wanted to connect this portable HD with my S7 Edge. Thanks!
Now I have a different issue.
On the S7 edge, it worked flawlessly, as long as it was formatted as FAT32 or exFAT. (NTFS worked if the phone was rooted)
On the Note8, the HD wont even power. I'm wondering if there's some secret config that could fix that...
Why would the Note8 lack the capability to power the HD when the S7 could do it.. odd.
For reference, this is the model of the HD: https://www.seagate.com/consumer/backup/expansion-portable/ (I'm using the 2TB version)
Hugs and thanks,
Dan.

Any ideas guys? I'm still a bit lost.

most likely a power issue. is the wire split into 2 male usb? one should go to a charger or power adapter and the other to your otg adapter to you phone. try swapping the 2 male usbs from power adapter to phone usb otg.
also try letting the device power on before plugging in your phone. i had the same issue with an external blu ray player i was trying to hook up to my phone.( i eventualy made it work, but i had also a mounting issue which i resolved with MLUSB Mounter app)

This portable HD only has a single cable... It doesn't even need that much juice to run.
What Is really odd is that I could use it with no issues on my s7 edge.
I'm wondering if usb type-c unable to power the device. Or if there's some hidden configuration that will allow it....Or in the end I may have a crappy adapter... In any case... Frustrating.
