It dose not affect on the FreeBSD. >> Also there is usbdump -i usbusX -f Y -s 65536 -vvv, which will show the >> actual >> traffic. ! This is very useful. $ usbdump -i usbus2 -f 4.0 -s 65536 -vvv (unit 4) $ usbdump -i usbus2 -f 4.130 -s 65536 -vvv (unit 4, endpoint 0x82) I have compared with other application (pwcview). There are a lot of VS_PROBE_CONTROL transfer than expected. But it may not be a problem because I have tried these transfer reproduced from dump data. The problem I noticed is that the libusb_claim_interface of my code is not logged. Is this function really implemented? 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"
