Hello devs and all miui fans
So, its already about months by now having problems with USB tethering/MTP mode. PC noticed like "USB device malfunction...."
I cannot conected my device to PC via MTP mode. I was tried to On/off debugging, on/off mtp-ptp (in CusRom), switch USB Cable, but all of that suggestions doesnt working.
There is no option but charging when i connected my R2P to PC via USB cable,but the strange that is "i can flash via fastboot, means that there is no issue bout cable/pc/or my device hardware right?"
Already tried many ways that available in this forum or outside (sorry cannot attach link, im too confuse lol) such 3rd party app, clean re flash STOCK ROM, and intsall/uninstall drivers on pc, but the problems cannot fixed.
please help me, im desperate and you know how useless smartphone if it cannot transfering media data from/to PC via MTP. I've attached screenshoot from setting>network>more>and there you can see that the usb thetering option are disabled (grayed out)
Thanks, and sorry bout my english

Hi guys,
After upgrading to ICS I've been unable to connect my pad to the PC. This is usually not a problem, but last night I needed adb to re-root it. Nothing worked, nothing connected. Tried installing drivers and the Asus sync, but no luck.
Is this a known problem? Anyone got a solution? I doubt it's the hardware as I connected a few days before upgrading...
Found a solution. Went into Settings->Storage and turned MTP off and back on.

THANK YOU! Everytime I plug in my ET4G to the dock to charge it that stupid MTP crap always comes up. Had no idea I could disable it. Thanks!
yeah, this doesn't always help... I had the same problem when i first got my TF101, and i tried all the tricks, the one mentioned here with mtp, enabling and desabling debug mode, turning off and on with usb plugged in, and some others i can't remember... nothing.
In case anyone else is looking for the answer and the quick tips don't work, what did it for me was installing Android Revolution HD rom. I've read that this problem could also be bootloader related.
Anyways, cheers.
How to connect an ICS device to your computer
Step 1. Connect device to computer via USB
Step 2. Set USB connection as Media Device (MTP) (p.s. if you use a Mac you need to download Android File Transfer)
Step 3. Disable USB debugging if enabled
I hope this helped.
when you need turn off MTP it mean your computer doesn't have driver.
If you need using MTP go to asus page and download driver. it's easy to install driver ^^...
recently I can't understand why same file but the computer at my office can't install that file instead other computers working normal... maybe my work place using old windows version...
Like I wrote earlier - mine was actually in MTP mode, but I had to switch to camera mode and back to MTP for it to start working. Thanks for the replies, though. Hopefully it will help some other people with the same problems

I have this exact same issue. Nothing shows up in the Windows Device Manager.. nothing changes. I've uninstalled all my USB drivers, reinstalled them, looked in USBDeview to make sure im uninstalling everything.. I changed usb ports, I changed usb cables... nothing at all works. I have no idea why, it used to work for me even. It used to work just fine, but then there was a stock patch awhile back that caused me to lose root and I havent been able to connect since.
Looks like without usb debugging , is atleast charging , but pc cant find my phone :/
Install the latest windows media player wm11 for media transfer protocol (mtp) drivers...

What Operating System are you using?
If you disable USB Debugging and connected it, do you see it in MTP mode, which let you transfer files to the phone.
With USB Debugging turned on, you need to install the ADB/Fastboot drivers, which is a different mode from MTP. Use the Universal Naked Driver in my sig and install it from Device Manager. You can use Google official USB driver too: http://developer.android.com/sdk/win-usb.html
If you have neither working, you need to fix MTP first.
Hello I have a strange problem I can not connect my p8 lite up to a computer or any laptop. It charges but does not detect for moving files over or anything else other than charging up. It detects when it wants to not when I need it to lol.
I have also tried the following
USB mass storage device
shows mounted but does not detect.
Tried new usb cable no joy
Have also gone into service menu using *#*#2846579#*#*
Then going into background services usb port settings and using manufacture mode als tried google mode and hisuite mode and still not working.
Any advise to fix and resolve this would be greatly appreciated as I need to update my phone and put new rom on but can not due to the above.
Hi
i cant connect my OP5 ( two days ago it worked) to my laptop
changed cables and usb ports with not success
this is what i am getting
"Currently, this hardware device is not connected to the computer. (Code 45)"
and after this i dont see even the yellow mark on the device manager
please assist
thanks
Sounds to me like an driver issue. Just install the platform tools again, reboot pc and connect your phone again. Or enable ADB and USB debugging again in Developers Options and reboot device.
Hi
How do i enable adb on the phone ?
Usb debug i enabled but it didnt helped
Hello guys,
after trying everything I could imagine and find on the net, I still didn't get my PC to recognize my S6 edge plus.
Hopefully someone od you has got some more ideas.
The Problem:
Connected Phone shows "Unknown USB Device (Device Descriptor Request Failed)" in the device manager. No MTP connection and no ADB possible so far.
Done so far:
Samsung USB Mobile Drivers
Kies
Smart Switch (with reinstall of drivers)
6 different cables with 4 PCs (2 Win10, 1 Win7, 1 Linux)
USB-Debugging on / off
*#0808# switched through every mode
USB-Hub drivers
Factory Reset
More Info:
5 of the 6 cables are working just fine for data connection with my S3
There is no infobar tooltip to change USB mode at all, just telling me it's loading
In Download Mode the phone doesn't get recognized by Odin (with same cord and USB Port the S3 does)
In Stock Recovery Sideload Mode the Device does not show up in adb devices (with same cord and USB Port the S3 does)
Regards
up
I'm guessing you have downloaded and installed the Samsung drivers?
New Infos on this case:
Local tech support inspected the phone. They suspect the mainboard to be defective due to corrosion signs.
Of course the repair cost would be ridiculous.
I'm gonna repair it myself, but I'm not quite sure if it's really a faulty mainboard.
I rather think of changing the USB board first, because it's like a 10th of the mainboard and more likely to get wet if that's the reason for the damaged phone.
Any ideas??
Regards
You didn't mention if it charges via USB?
Im in the same situation..
charge via usb but is not able to recognize the phone in any computer (a lot of different cables with 3 PCs)
My unit was wet and i think that something is wrong for this reason.

Hi Cento50. Have You managed to get the phone to work? At first my phone was showing up in "This PC" on Win 10. but after trying Samsung usb drivers to get Odin3 working now it is the same as Yours. Shows in Device Manager as: Unknown USB Device (Device Descriptor Request Failed). A strange Conundrum.
Hello @Photobil2012 yes fix habe worked!
One little wire have replaced 2ohm resistor.
And have fix fast charger and data comunication with PC!
We i have repaced first one diode.
Phone a this time work complete.
First this problem i have connected one hard disk to otg cable with phone battery low!
My suggestion Please caution to use otg interface with high current if have low battery in the phone.
This cause high current drain and possibile burn diode and resistor.
Hi Cento50,
Alright! Thank you very much for the most timely reply and tech info on the successful fix. This is very good news to receive. I just replaced the battery so it is brand new and that works fine now. However, if it is necessary I can apply the same type of fix that you applied. Great work, and thanks again for your help.
