svn commit: r351967 - head/sys/dev/usb

New Revision: 351967

Log:
  Some newer HID devices have descriptors that are larger than 1k. Bump
  this to 2k to prevent them from being truncated and ignored. It
  appears to be a sanity check only, but bumping it to 2k allows both of
  my iic hid devices to be parsed and the second one to work...
