VR-730 no power to USB

Post by georgem »

My VR-730 is not providing power to the USB memory port. I discovered the problem when I plugged in a wifi adaptor I had tested on a pc, and it didn't work in the VR.

I did a factory reset, which didn't help. OS version 1.12 is installed.

Can anybody offer advice?

It could be that there is no 5 volt power
to the USB port as seen on the schematic. Have you tried
providing your own external 5 volt supply
to the wifi adaptor ? It might then comm
with the 730. Worth a shot
