Hi to all, I have a big problem. I have upgrade bios of Chuwi Hi8, last version posted on Chuwi Forum (build date 23/12/2015). Now, in Windows 10 (build .164) and Android stock, USB otg doesn’t recognize nothing!!! I plug pendrives, mouse, keyboard, in two different otg cable, but they are not powered.. but if I use hub USB powered, connected with the same otg cable, they work all!! Is it an electric issue? Only coincidence with bios upgrade? The day before upgrade BIOS, for the first time in 6 months, the tablet for 20 minutes not recognize the USB charge (with 3 different charge…), no charge and no led charging.. after 20 minutes it works..and I have decided to upgrade bios the same day. Now USB charge works, but not USB OTG not powered.. can I try to flash previous Bios (build date 30/05/2015) or not?
