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.. 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

Happy new year 2013 to all.
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

[Q] Sony Xperia T haven't OTG official?

Plz tell me: No. Thats have support of otg fabric.

I have no idea what it is you're asking, but if you're asking if the Xperia T has support for USB-on-the-go the answer is YES. Xperia T supports USB OTG by default. I used it on mine today to restore a backup from a stick.

i can confirm too... otg works..

So then it is weird that usb host diagnostics says it does not work on the LT30p?
Or maybe there is a problem with the test procedure for the diagnostic app?
I am looking for a phone with OTG (maybe cheaper than the T), and my two sources are XDA-dev and http://usbhost.chainfire.eu/, and sometimes they do not agree...
Maybe someone with a T should try a test with the app and report it to the host diagnostics dev, as I thought chainfire's site was a great source for info.

I also have the same problem as OP, i made my OTG lead by cutting a usb extention and splicing into another usb extention in effect creating a Y usb with females on both ends, the reason its a Y is so i can add power to the cable from the male end and not have to chop up my usb micro-b cable, this worked perfectly on my htc hd2 with usb host mode files enabled but doesn't seem to function on the Xperia T, i'm running the NXT r2 rom which is based on stock so usb otg should work right?

[Q] usb connection

When I plug in a usb stick through the cable, I can not see or make the connection. You will need some setting or app? Even with usb debugging on. Any suggestions.

try going into the phone settings and then click on storage and press the button on the bottom right of your phone and click the words usb connection(or something similar) and if that takes you to another menu then click mass storage device

can't connect phone on PC
Hi,
I have same problem, recently I installed windows 8 and since than I can't connect my phone via USB cable.
I have installed LG PC Suite and nothing.
Please help.

So you are trying to connect a USB with an OTG cable.. so you can view the files of your USB on the phone?
I read in another thread / article that the kernel does not support that on our phone. For that we need a customer kernel which hopefully will come once we get unlocked bootloader.

That's right. This kernel does not support OTG. I tested the hdmi connection to the TV and that yes, a spectacle.

[Q] USB OTG problem on galaxy tab GTP1000

Hi all,
My interest these days is to make the USB OTG working on the GT-P1000 thing that cannot be done via a standard OTG cable. When i started searching in the internet i found a video on how to mount a sub stick on a GT-P1000 using a usb Y cable (3 males), the samsung charger (with the cable of course) and 2 sex changers (female-female USB connectors), i made my own Y cable as it's not easy to find one in the nearby stores, here attached the cabling schema (i will be grateful if someone can check it) and also my device properties.
The problem is that the tab couldn't recognize any of the USB devices, despite that i tried the overall settings of the USB Host Controller application, so can someone help me solving this issue please?
FYI my tab succeeded the test performed by USB OTG Checker,
Many thanks in advance for your help

As I said in my initial post, the standard OTG cable doesn't work on the GTP1000, but some people (in youtube) succeeded somehow to connect a USB device to their tablets using Y cable (made from different usb connectors) and the standard charger, i want to know how this Y cable was made.

Yes. The reason is very simple. There is no +5 V (supply output voltage) on 30-pin connector.
---------- Post added at 01:27 PM ---------- Previous post was at 12:58 PM ----------
I use the next algorithm:
1. Make initial corrections with USB Host Checker.
2. Reboot
3. Connect flesh drive to USB hub (with external supply).
4. Connect Tab to USB hub.
5. Start USB Host Controller:
Default operation mode - Set to auto-host mode
Operation mode - Auto-host mode
USB host driver - S3C HS (USB2)
Mount Points - /storage/UsbOtgDrives
6. Scanning process may take a long time - up to 10 minutes.
When scanning ends, go to the 2-nd tab of USB Host Controller.
7. Click on flesh drive and choose Reset.
8. Start USB OTG Helper.
9. Mount flash drive.
10. Profit!

Thank you MarviXDA for the detailed procedure, i will try it and let you know the result asap.

Hi MarviXDA,
I have tried your procedure but nothing happens, (no drives found), attached are some screenshots for your information
https://drive.google.com/folderview?id=0BwDz7pSse7yJc21WZ200bDZ1MEE&usp=sharing
Do you have any further tips?

Can you find 2-4 Gb flash drive with LED indicator?

During the scanning process (Step 6) indicator is not flashes?
If it so, may be bad electrical contacts?

The indicator didn't flash in any step, btw the scanning process didn't take more than 1 second, i don't know why.

Make sure that power is supplied to the flash drive. And check the voltage polarity.

Power is correctly supplied to the flash drive (polarity is ok), but i noticed that the indicator flashes only when D+ and D- are connected (to PC for example), MarviXDA, can you please take a look at the attached cabling schema in my first post and tell me if it's correct?

Yes. it's correct.
Only one remark. Too many connections. I use the Y-cable - male and 2 female. And my cable is short - about 20 cm.

[Q] Possible to disable USB Host Mode?

Hello everyone,
Here is some background information to give you guys indication of what's going on:
- Phone charges fine though HTC charger and USB.
- Phone detects MTP fine when connected to the computer and charges as well.
- When placed on dock (connected with HTC cable and charger), the phone says "can not charge in USB Host Mode"
I've scoured these forums and tried some of the solutions posted. My question is that is there any way to just disable USB Host Mode all together? I know based on my usage that this feature will never be used by me.
Thanks everyone

Exactly the same problem here
Any solution for this?
Thank you.

This (https://github.com/mehrvarz/android...mmit/6be86fe2c73f626630329982aaa7731525de6078) is how Timur made his Galaxy Nexus kernel be able to do this. Don't know if you could talk a kernel dev in to trying to incorporate this or not. Note: this method (for the Nexus, at least) won't power devices while in host mode but will accept external power via a Y cable
