Hi,

PicoMiteVGAUSB (no matter, which Version) doesnt seem to like my 7 Port USB Hub, which uses a HS8836A Chip (USB2.0). If a USB Device is connected to it, PM responds with "Invalid Address- reset" = General fault. This is independent on which Connector the Device is being plugged in.

Is it likely that the Chip tries to allocate more USB Channels (7) than the USB Stack could handle / is configured for (4), when a Device has been plugged in?

Edit: Tried to make some adjustments in tusb_config.h, but that doesn't resolve this issue.

Best regards
Stef
