Dear Friends,
My Le1s now facing a problem with the USB connection. It does not showing USB connected notification. And PC shows that USB device is malfunctioning.
I'm planning to flash a new rom. But due to this problem I can't do anything. Please help.
Is it charging while connected to pc ??
If answer is yes..
Then ur usb type C cable is problem
Buy another one to make sure the problem...
If answer is no..
Then try the services of local authorised serivce center..
Or flash same rom..
my device is charging and showing usb debugging
but i want to unlock bootloader and when i type adb reboot bootloader the fastboot mode turns on and then it shows on my pc usb device malfunctioned
and when i type next command it shows on my pc searching for devices

This happens today as i am debugging a little program of mine. Suddenly, the device stops from being recognized on both macs and Windows. At first i thought the mini usb connector was faulty however, i connected the cable and it shows that it's charging. However, when i do ADB devices.. still no devices found.
Can anyone provide a solution to this?
Tried enabling usb mode on and off, restart PC and mac. nothing works.
Thanks.
What rom use....? Stock or dev. ????
If your dev. rom ....you should off the debugging

Dear all,
Please Help me. My One plus one is on CM12 official rom (rooted). Problem is when I connect my phone to computer and use ADB it is detected (adb devices: number & devices detected) but when in fastboot (fastboot devices : nothing is detected) I check in my device manager (yellow triangle on android ) My problem is why CAN it be detected when my phone is on but NOT during fastboot.
Necessary checks done : USB debugging, Universal driver, SDK installed, USB driver reinstalled again, tried changing usb ports on computer, tried on 2 laptops)
I am helpless, tried checking on forums can not find the answer.

Tried adb reboot bootloader then phone boots into fastboot mode but from here..
is total no connection. Tried checking fastboot devices (nothing), fastboot reboot (waiting)
then i tried as u said unplug & plug in (not recognize) from here adb cannot be written anymore. (no more commands can be typed). Tried others like down loading Pdanet ,force install driver..Nothing works. Thinking ,did I corupt the bootloader while I was rooting it last time.?
I think if something was wrong with bootloader you could not either boot .
Do you use antivirus to pc?
Try without antivirus
What happening the false is from computer
Mine is reverse issue. When in fastboot mode, pc recognizes OPO, but when OPO is normally connected to pc, adb is not working. Its charging and can transfer data through USB, but OPO is not recognized through adb commands. Device Manager too recognizes my OPO only when it is in fastboot mode and not when normally connected via USB for data transfer.
I have a software, through which I can REVERSE TETHER my PC's internet to my mobile via USB. Because my OPO is not recognized via USB in normal mode, I can't do that. Any idea, what's wrong with my OPO.
(I have installed Android SDK and google usb drivers, for my OPO to work in fastboot. I have rooted. My pc runs on win7)

Install pdanet+ for win
Trying to unlock bootloader, upon opening command prompt via minimal adb fastboot, after entering "fastboot flashing unlock" instead of completeing the process, I'm getting a "waiting for any device" message instead.
I'm unsure if this newly discovered usb 3.1 port on my pc is even the right port for this usbc cable, as I've never used it before now.
Windows recognizes it as MTP usb , but I can't access anything, it's empty when I open it. So I don't know if it's the wrong port, and maybe I actually need to buy a USB to usbc cable from Google (tried the one that came with my V30, got same message) or if it's something else I'm missing.

hey thanks, that worked. Considering I've only had 3 rooted phones in the last maybe 8 years, I tend to forget those prerequisites
