Hi,
The set config message is sent on the control endpoint. The set config message
doesn't have any data stage, so the USB stack is waiting for the status stage
callback. Either that is caused by:
1) Lost interrupt on EHCI
or
2) Device never sends the status stage (needs a bus analyzer for this).
Quirks you can set in /boot/loader.conf:
hw.usb.ehci.lostintrbug: 0
hw.usb.ehci.iaadbug: 0
--HPS
