Hi Ed,

Have you tried to edit "max_usb_current" in /boot/config.txt?

Try to set it to 1 or something.

Example:
max_usb_current=1

Thanks, that was the winning tip!
The BQ is charging now, without a hub.

The interface on the BQ goes up and down, so i might have to tweak theamount of current drawn by the BQ.

Any idea on how to do that?


Kind regards,
Ed
