Need some technical help

Hey guys,

I had a loose 12v+ wire hanging near USB ports (my fault to not isolate it from the board) and it has shortened to USB ground. The board is working though none of 3 USB hosts seem to function if I'm trying to connect any device. There is 5v power coming out of USB ports but no response in android that anything connected to the system. WI-FI doesn't seem to work as well. Is there anything I could do to bring USB & Wi-FI back to live? Thanks for any help.

Seems like usb hub is dead. Does anyone know if I can somehow use USB-OTG as USB-HOST? Thanks

Yes. You can buy an OTG USB mini to Host adapter cable.

Works like a charm, thanks
