Thank you rajivshahi for your answer and attention.
I had try all the methods that I find in hole of internet!!
also I tried your suggstted method. I was connect my phone with ans without SIM and memory to each USB port of my (and another) PCs, I changed my USB cable for several times, I also tried Uni_bootloader program and MTTY but they didn't work (because there is no USB connetion with my UNI and my PC)
I just keep crying!!!!!!
Have you tested doing Doc format?
Hope it helps,
If the device is not recognised by PC at the same time as Serial not changing to USB, I would think your USB port is no longer attached as it should and can cause the problem you described. From time to time USB port might still feel and look secure on mainboard, it will even charge the device, however, when it comes to AS and USB connection to PC, it will not connect properly.
That, or your PC USB or motherboard are malfunctioning. Try other USB devices in the same ports.
My PC's USB ports are work properly because as you told enigma1nz, I had test them with another devices
For the DOC format method: there is no USB port for connecting with MTTY!
Soooooo amazing!
(thanks for all your answers)
So, it means there is no way for me
hey,
have you disabled (unckeck) USB connection for ActiveSync/WMDC at PC?
do it now or USB port will not be available for mtty.
also please make sure that you installed XP sync driver under vista incase you're trying from vista.
follow the same -
1. unckeck USB connection for as/wmdc at pc
2. reset the device by pressing reset button
3. set bl mode (if not there already)
4. connect usb cable
5. start mtty ...
Hi Tomal, first I have to say: Thank you for your amazing roms. they are so fast, nice and stable. I'm one of the biiiig fan of your roms.
seconed: yes I was disabled the USB connection and also kill ir from task manager. but my Uni is still deeaaaaaaad
somehow I have a feeling that something is wrong with the usb port in device. may be connection is broken or something...
Hi everyone,
finally I had to send my Universal to doctor! , he says that I can load your device from SD card, and boot up it, (flashing card)
!!
I was wondered! what is flashing card! (load from SD card without any PC!)
Do any one have some information about this method!!!!

Yep, it does look like your device's USB being a culprit.

Xperia ARC S USB OTG possibilities

ARC S (LT18i) comes with USB OTG support but when I plug an USB memory stick it recognizes it but says it's not supported.
From what I read it only works with LiveDock which is, by my opinion, not good at all, not even a real dock since you have to plug a cable in phone.
so is there a simple possibility to make USB work without LiveDock?
by simple I meen without flashing a new kernel
Thank you
See this thread: http://forum.xda-developers.com/showthread.php?t=1224676
In short, you need:
Q5 Memory Manager: http://android.gval.biz/download/Q5_USB_Memory_Manager.apk
Module Loader: http://forum.xda-developers.com/showthread.php?t=1228605
usb-storage module: http://doomlord.sylvester20007.com/xperia_2011/usb_otg/v01/usb-storage.ko
You can then connect and mount USB flash drives (formatted FAT32) with a suitable USB-OTG cable.
Hi
a cheap wireless keyboard/mouse bundle works perfect with a cheap otg cable.
usb hub too.
Managed to use usb key with XTCrefugee explanations.
But, could we charge the battery, at the same time using usb devices?
arc S
otg with unsupported USB
Getting the same error message, I have Astro file manage.
Unsure how to mount USB drive.
Get this app, it does the job nicey http://forum.xda-developers.com/showthread.php?t=1389653
PM me if you would like a copy...to test out
Thanks for responding, but I see the linked app requires rooting etc. There appears q5 but that's not on plaststore. Would upgrading to ICS be solution or a problem. What would you suggest?
When I had ICS installed still need to use some app to mount USB stick ... I have to say that Nokia N8 and other new Symbian devices have better support fot USB OTG ...

Have you installed every driver you need?
Try USB 2.0 AND 3.0 Ports.
Is the Kindle Fire in a good condition? (No accidental damage, good envoirment conditions, etc.)

Can you boot to your OS? If you can, then does your computer detect it then (if that's not where you were trying to get it detected in the first place)? What OS are you using (both on your device and PC)?

PS4 controller on S4 Mini Duos problem

Hello everyone!
I have got a Galaxy S4 Mini (I9192) and I try to connect my PS4 controller to it, in order to use PS4 modded remote control app, but the phone does not recognise it. I use CM13 latest build by @csendre , custom kernel by @DarkFrenzy and TWRP 3.0.2-1 by @ne0zone75 as well, but I cannot control the phone through my controller. Inside TWRP, in mount option, I cannot enable USB OTG, and using OTG Troubleshooter app, it has crosses on two last lines (not recognized by Linux and not recognised by Android). I have also connected USB flash drive without any luck... So, is there any way to use USB OTG or is it a hardware limitation of the phone?
Thank you a lot!

I did not use a controller with the S4 mini, however I used USB OTG functions with no issues, but you need to supply power so use a Y cable. Our hardware can not supply power through the USB port

HTC 820 (Stock/6.0.1) won't recongnise OEM Wired Xbox360 controller

Hello guys, as you can see in the title I have a problem with my non-rooted HTC desire 820 running on stock rom (updated to 6.0.1 Marshmallow) , my phone can't seem to recognize my xbox 360 wired controller.
I know that the phone is OTG compatible(I can't attach photos because I'm a new user ), but USB OTG Checker shows that phone is compatible, and the controller as pluged in ,USB Host Diagnostics says(All yes except Rooted API and this -> ): "Kernel Claims support:YES / Device detected: No / Verdict OS,3rd party apps No/NO " . My wireless mouse and keyboard are working when connected(same for the usb stick). Xbox controller works on another Marshamallow android device with the same OTG cable. I updated kernel ,but with no solution , i can't seem to figure it out. If you guys can offer any support , I'll be thankful. I have to mention that I would like to exclude rooting because my warranty can be void.
Hi, you can't do anything without rooting because stock rom doesn't has x360 controller drivers installed and if you want to install it you must have root privileges
