This appears to have no effect--the device still repeatedly disconnects. > Also run usbdump to capture the USB traffic. > > usbdump -i usbus1 -f 7 -vvv -s 65536 A sample dump is available at: http://n.ethz.ch/student/dlin/aos/usbdump.txt Although I didn't understand the dump, I tried tracing the code. The device is disconnected when usb_free_device() is called within uhub_reattach_port() (the repeat part) in sys/dev/usb/usb_hub.c. I'm not sure what triggers this though. -- Denny Lin _______________________________________________ freebsd-usb@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-usb To unsubscribe, send any mail to "freebsd-usb-unsubscr...@freebsd.org"
