Yes, I tried this too because usbdump of the pwcview use this value.

I compare with pwcview + webcamd using ``usbdump -i usbus2 -f 4 -s 65536 -vvv'' the noticeable difference is existence of the SET INTERFACE request. >> libusb_set_interface_alt_setting(handle, 1, 1); >> libusb_control_transfer(handle, 0x01, 0x0b, 0x0100, 0x0100, NULL, 0, >> TIMEOUT); Thank you. --- SAITOU Toshihide _______________________________________________ email@example.com mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-usb To unsubscribe, send any mail to "freebsd-usb-unsubscr...@freebsd.org"
