`hid-open` doesn't allow omitting serial-number #2

The hid-open procedure has a mandatory #:serial-number parameter, of type string?. In the C library, the sample code begins with:

handle = hid_open(0x4d8, 0x3f, NULL);

showing that the serial number is optional. In Racket, it's a non-optional keyword, and passing #f throws a contract violation.

Thanks for your report. I will fix it over the weekend.
