Hi,
I like to attach a USB device to my phone. Is there any way to make my (rooted) device to act as UBS HUN and work with connected USB devices?

Hi,
I've been trying to figure this out for almost a year. I got a cheap Chinese tab with a microusb and a microusb host port. If my rom and kernel have usb otg support, drivers etc. (according to the usb host diagnostics app) why would my usb keyboard and mouse (and usb storage) not work with a nonpowered or even through a powered usb hub? Is there something I'm missing? I've tried stock rom, official update and even a custom rom with usb drivers. So one app gives me S3C usb host missing...and usb host diagnostics says kernel and rom support it...there are drivers which I checked by a root browser. I've tried with nonpowered OTG as well as through a powered usb hub. Nothing works. What else should I have?
Thank you!
EDIT: Found something interesting. If I connect my usb port to power and my keyboard or mouse to the usb host port, then they are detected...but if I disconnect the other port from power they DON'T work. I tried using a powered usb hub on usb host port...does not detect. Is this a problem with usb modeswitch?
Hello
I've got Lark Freeme 70.65, it's a cheap tablet based on Allwinner A13 procesor. It was allright till yesterday. I installed here CWM and Cyanogenmod 10.1 from there and it still was allright. But then suddenly, when I tried to replace camera drivers, everything collapsed, touchscreen is completely reversed in Y axis and it ain't got it's full range, so it was completely unaccesible. But it wasn't so bad, I did recovery of my stock rom from CWM mod, then once again installed cyanogenmod 10.1 and I did few experiments. It was nothing that would really hurt it, but I was so unlucky than in one moment every one way of access to the tablet failed. So right now I cannot use USB connection in any way, CWM when I try to recovery says about 'MD5 mismatch' (I haven't touched clockworkmod folder at all!) and I have touchscreen that is responding but is completely unusable.
Of course I tried different USB cable, different computer, different system and everything. lsusb can't see device at all, so do ADB. dmesg says this:
Code:
[91554.840089] usb 4-6: new high-speed USB device number 10 using ehci-pci
[91554.984872] usb 4-6: New USB device found, idVendor=18d1, idProduct=0003
[91554.984881] usb 4-6: New USB device strings: Mfr=2, Product=3, SerialNumber=4

[91554.984892] usb 4-6: SerialNumber: 200804116426ef0
[91554.985969] usb-storage 4-6:1.0: USB Mass Storage device detected
[91554.986928] scsi8 : usb-storage 4-6:1.0
[91555.561110] usb 4-6: USB disconnect, device number 10
so it connects disconnects immediately after plugging the usb cable.
It would be great if I only could restore touchscreen or usb connection. I thought that replacing the rom would help, but CWM can restore them only from zips, and I have only imgs and I haven't found any way to do this.
I'm starting to accept my sytuation, this device was very cheap (170 PLN, it should be about $60), but it would be a great experience and happines for me to repair it. If anyone have got his own lark freeme 70.65 backup from CWM or any other Allwinner A13 and could upload this for me, I could try it out from any SD card (sadly I lost my own backup). Any other propositions also in common.

Hello,
My phone is turned off and when I connect it with my laptop (same with my PC) it keeps getting disconnected and reconnected. My phone is ZTE Blade Q Maxi.
First, I thought that the problem was my USB cable or USB slot, but in the end, they're okay. The drivers I have installed on my laptop are following: Android ADB interface, DA USB VCOM Port, Gadget Serial (there's probably more, but they're seperated in categories). I noticed when I connect my phone, 1 driver appears - Preloader USB VCom port, about 2 seconds becauses instantly it gets disconnected.
Currently, my phone is bricked, but I've had this issue before.
Any help would be highly appreciated.
Thanks in advance!
