Hi.after clean my device no read from usb hub.i can’t boot or reinstall or flash.no read usb.
Thank you

Have you modified anything in the Bios? You will not have disabled the USB ports on the Bios?

Hello, I accidentally stopped the USB port on the BIOS, now I cannot enter the BIOS settings, how to restore the settings? Thank you!

By disabling the USB port you will not be able to use any keyboard device to access the Bios.
The only valid solution is to reprogram the bios with an external programmer.
Anyway, try this in case it works:

  1. Press the power button for 30 seconds
  2. Press the power button three times in short half-second presses
  3. Put the charger and press the power button until it turns on and check if the bios has been reset

I tried the method of pressing the power
But useless
Can you teach me how to reprogram the BIOS using an external programmer?

Thanks for your explanation
Unfortunately, I have no tools
I can only be disappointed with my vi8 now…

You can get everything you need for very few euros on Ali Express

Thank you for your suggestion ~

I finally successfully loaded the BIOS with the best preset value

But there is still no otg function in this mode

Therefore, keyboard and mouse USB devices cannot be used

Is there any other way to reinstall?

Everything is because the KMDF HID Minidriver for Touch I2C driver does not work properly in win10

can you shate how you enter bios finally

There was no otg before, so entering the BIOS is the reply option of Win10 → Troubleshooting → UEFI enters the BIOS
Later I found out that I set the wrong otg device 1.2.3

Now, there shouldn’t be too much problem entering the BIOS
