How can i see if i have closed USB ports? I don't have closed anything, i have only upgrade BIOS and also installed by zero windows 10.. And USB not powered don't works in windows and android... How can i clean BIOS? Is it sure that isn't an electric issue?
I have restored bios default setting,but otg (not powered) don't work.. Maybe it is an electric issue? It is strange that usb otg works with hub powered in android, windows and boot, but not powered not works in all.. Can you ever heard a similar issue?
I don't have changed nothing in that windows settings. Repeat, my problem exist also in Android..
The answers are two:
- Bios problem after upgrade
- Hardware issue
In both situations my experience with Chuwi is finished.
