 Hans Petter Selasky posted a small patch:
 
 http://lists.freebsd.org/pipermail/freebsd-multimedia/2011-April/011931.html
 
 Would you please give it a try?  With that patch, I do not
 need the "usbconfig do_request" command anymore with my
 C210 or C310 HD.  I still need to do a "usbconfig reset",
 though.
 
 Best regards
    Oliver
