Hi, USB is only draining from "usbd_transfer_drain()" in /sys/dev/usb/usb_transfer.c . You could add a print including the backtrace and see if that function gets called when it freezes. Else I would try to compile a fresh kernel from USB P4. There are some patches there in relation to the recent newbus lock change, that might help. USB uses uppercase "WDRAIN". Is your printout lowercase "wdrain" ? --HPS _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-usb To unsubscribe, send any mail to "[email protected]"
