It dose not affect on the FreeBSD.

! 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.
