I've got a machine running Windows 7 (x64) that has only a couple of USB 3.0 ports.
ADB and Fastboot drivers from Flashtool are installed, and ADB works fine.
Fastboot, however, does not. Pressing VOL UP while connecting to the PC doesn't do anything, and the phone just starts charging. The last time I faced this problem (on a different m/c), I just switched to a USB 2.0 port. Can't do that anymore.
Is there a solution or workaround for this issue? The USB 3.0 drivers are by Intel, not Microsoft.
Just found this solution.
Go to BIOS > Advanced > USB > XHCI and change the setting to Disabled.
This will make the ports run in USB 2 mode, and fastboot works as usual.

Its 2020 right now and laptops are having only usb 3.0 or 3..1 ports and their bios don't have the xHCI mode so we can't enable usb 2.0 from the bios so we can't do the basic fastboot command to flash TWRP
so further testing is not possible in new mobile and we can't have usb 2.0 all the time so there must be some solution for this.

You could try using a cheap USB 2.0 hub if nothing else works for you.

When I Switch USB Debug(turn on or turn off) when USB is connected, the staus bar will show USB option(PC mode,USB mass storge,charge,etc..)
But no matter what I choose,It does't work.
And when I run adb command(usb debug on) , It shows "device not found".

I had changed ports ,and USB cable
And windows xp and win 8.
But It's the same.
are you using the stock usb cable?
are you running a rom?
what recovery are you using?
if you have a custom recovery hook your phone up to your computer and boot your phone into recovery either cwm or safestrap
go to mounts and storage and try to mount sdcard and see if that works
p.s
make sure usb debugging is enabled and check mass storage in the drop down
Was there ever a solution found? My droid 3 for some reason the usb debugging isn't working, the computer sees it and I can access my files, but debugging won't enable. I turned it on and off in settings a bunch of times and tryed a few different drivers
hello guys can you help me coz i cant connect my lg optimus 2x to my pc

please dont use any USB hubs...connect it to the USB port on the motherboard side....normally on the rear side for the Desk tops.....on the laptop all ports are directly connected normally...
secondly, what is your config? ROM?Kernel?please state your current configuration which can allow others to understand the situation.
Thanks
yeah i dont use usb hub i connect it directly i tried it on my laptop but its not working
my o2x dont say that usb debugging is connected it only charge
im on stock GB now 2.3.4 v20g
Don't want to hijack this thread, just got the same problem. (Not a complete noob here, rooted lots of different devices)
Bought a used 2x today. Froyo 2.2.2 german stock on it.
It just doesn't show the prompt that USB is connected
Tried:
- LG Mobile Driver from version 2.x.x up to 3.7.2
- on Win7 32 bit, Win7 64bit, Win XP 32 bit on various USB ports
- LG PC Suite obviously doesn't connect too
- checked/unchecked USB debugging, USB mass storage and all the obvious settings
- tried different cables
Would be really great if someone experienced could point us in the right direction.
EDIT:
After lots and lots of google I found out about a menu when dialing: 1809#*990#
With these options available:
CP Image Download
FET Disable
FET Enable
AP UART
CP UART
AP USB
CP USB
CP UART gave me at least a life sign once by saying that Windows wasn't able to recognize the device.
Is this issue really unsolvable?
Sorry for the bump, but I got some update.
when dialing the above mentioned 1809#*990# in the Port menu, switching from default AP USB to AP/CP UART gave me life signs.
After switching to AP UART I linked the Unknown device driver to lgusbdiag.inf located in C:/ProgramFiles(x86)/LG United Mobile Driver.
Suddenly it started installing it and is now recognized as: LGE Platform Android USB Device.
Once disconnected I lose USB again, I'm able to recreate the first steps though even in default AP USB mode by now.
The only thing I need USB for is for flashing a custom recovery but the only thing I don't have is ADB somehow : / Clockwork telling me: device not found.
Any help on this one?
any idea guys about my problem?
Have you tried my method?
After manually installing drivers with CP UART on, switching back to default permanently enabled access with default AP USB settings as well.
i tried that but it only charge
theres a weird thing in my cp when i switch to cp uart my o2x says it charging even i dont connect it to my pc or charge it
Ap uart - p990 / p999
I have LG P999. rooted and cyanogen.
None of the special DTMF dialing # codes is not working (also code changed from 990 to 999) (i sow some other in another posts)
is anybody know a way to change to AP UART by software (with eclipse...)
or with a special cable?
i need to use AP UART - meaning to have a serial com in AP(app).
Thanks,
Tamir
guys,
Have you tried to install MyPhone Explorer and try the same....it can connect your device via wifi,USB or Bluetooth....so some way should work....
any Android version above Froyo(included) should work....I use this always...one of very useful and bug free apps.
Try it
After installing the dual boot bios on my teclast air III (M5C5) I tried to install Windows. Unfortunately, just before completion the installation was cancelled because of the following error: "Windows could not update the computer's boot configuration. Installation cannot proceed."
If I start my tablet and choose Windows, I get the following Recovery page:
The boot configuration data file is missing some required information.
File:\BCD
Error code: 0x0c0000034
You'll need to use recovery tools, if you don't have them...
Press the WIndows key for UEFI Firmware Settings

Of course I've tried to press the Windows key, but nothing happens. I've tried all keys and several common combinations, but none of them did anything, except spamming Ctrl-Alt-Delete, which forced a shutdown.
I can enter the BIOS, but for some reason there's no option to select Boot from USB stick (only UEFI OS and Windows Boot Manager). The strange thing is that I've used this usb stick to install Windows on the tablet in the first place and I've tried both GPT and MBR and used a usb 2.0 stick in a 2.0 hub, so the usb stick shouldn't be the problem I guess.
But probably even worse is that I cannot get into DNX mode anymore, so I can't install Android either. If I try I get the following message (instead of " Waiting for fastboot commands" ):
BOM Selection Switch (SW1B1) has been changed, but cannot take action. system will reset in 3 seconds
Click to expand...
Click to collapse
For some reason there is not much information about this error message and I could not find solutions to a similar problem ("BOM selection switch SW1B1 has changed Force_Windows"). In a desperate attempt I've tried to enable fastboot in BIOS to see if that would make a difference, but it doesn't.
Any help is welcome, thanks in advance!
Are U sure you have flashed/installed the right BIOS/Firmware ? double check it !
Also if your USB drive is USB3.0 your hub must be 3.0 too OR you must connect the USB drive directly to the OTG cable.

It was a 2.0 drive in a 2.0 hub. But I've tried with a usb 3.0 stick in a 3.0 hub as well and that doesn't work either.
I've had some problems flashing the BIOS. Initially I tried the simple method using the UpdateIFWI app (using the Mirek V7 rom and downloaded the UpdateIFWI app seperately) with the bios "Dualboot Bios Tested C6J6 And C8J7" from here, but that didn't work. Then I used the Mirek's flash tool to update the BIOS and unfortunately selected the latest version, which apparently is not compatible. Luckily DNX mode worked and I could use the tool in this thread to flash the correct BIOS. I used the dualboot bios from techtablets. It finished with FPT operation passed, but did not automatically reboot. After manually rebooting, it launched the screen with the options Android and a small Windows logo. I selected Windows and it started the Windows installer from the USB stick and the rest I've described above. If I start my tablet now, the Android and Windows logo are equally large (so it did install a part of Windows?). Unfortunately I haven't checked if DNX mode worked between flashing Dual boot and installing Windows.
I've ordered an USB programmer already
I'm about to convert my phone to the WW rom; but I am at an impasse. Any help would be greatly appreciated.
My phone is unlocked as verified by the security message and I can get into fastboot. I have developer mode and usb debugging enabled. When the phone is on, and also when in recovery; the phone will return the serial number with the adb command. When I reboot into fastboot, the phone is no longer detected. I have tried a USB A to C cable, USB C cable, and a combination of USB C, USB 2.0 and USB 3.0 ports on my computer. I have used both the side (blue) and bottom USB ports on the phone, but to no avail. Other odd confirmation is in the device manager my phone shows up as ROG Phone II, but under USB. I'm not sure if it is detected right; the screenshots I saw showed it detected as a device under another section in the device manager.

I had the same issue last update. Something in a windows 10 update broke fastboot detection. Use another computer with an older version of win 10 or boot a linux distro.

Try installing this version of adb/drivers
https://androidfilehost.com/?fid=746010030569952951
Once installed, the adb folder in root of C contains a 'cmd here' file, makes launching a cmd even easier!

Plug your phone on side port and reboot to fastboot then use this app to fix fastboot mode
If you already plugged the USB cable to the side port and still not able to use fastboot, it is probably a Windows problem. The Android fastboot exe is not properly signed so you need to disable Windows' driver signature check before installing the ADB/Fastboot drivers.
I cannot post link but search for "android fastboot driver disable driver signature enforcement". Disable the signature check then install the fastboot drivers.
Here is the quick run-down of the steps.
1. In command console and in Admin mode, run this command and then restart => bcdedit /set testsigning on
2. Install adb and fastboot stuff
3. After successful install, in command console and in Admin mode, run this command and then restart => bcdedit /set testsigning off
For ADB/Fastboot driver, i use the one by "fawazahmed0" here in XDA. The title of the thread is [Tool] Latest ADB Fastboot and USB Driver installer tool for Windows.
Okay, I tried all of the above; fastboot is still not detected in ADB, but it is detected in Recovery and when the phone is at the home screen. I noticed the phone came up under "Samsung Smart Phone" or some such in the device manager. I uninstalled and reinstalled and now it shows up as ROGPhoneII. However, same result as before. I tried the install methods on a secondary Windows 7 machine, but with the same result.

Hi ! I don't know why but I want to connect my Pixel 4a 5G Yesterday on my mac and today on Pc the pixel is not recognized.
I have uncheck usb debuging and check it again but not working.
My Pixel are on last Android 12 and root with magisk. it is possible that a mode can create a problem with the OTG ?
I have test on Safe mod doesn't work too
I have connect an usb type c usb key it recognize.
I have test connect on plateform tools and on terminal ./adb devices, have message on pixel to allow my computer and it recognize but not Android File transfert ?

I don't understand why ?
Thanks
Hi ! I post again because when I connect usb key mtp works and if I connect to my mac and go to settings usb parameters and choose transfert files/Android auto that work but never had notification pop-up for choose it
USB is a master/slave protocol. When you plug in an otg cable, your phone's USB controller switches into host mode. Your computer's USB is always in host mode. So your effectively trying to get two master devices to communicate which USB does not support.
