There are two reasons for that:

1. There are devices that do not provide device description:
   In this case, for normal devices, Windows gets description from INF file.
   Since there is no INF file for UsbDk devices, Windows may fail
   to initialize the device (depending on implementation of bus driver).

2. With this patch redirected devices show up in device manager as
   "UsbDk device" which is better then "Unknown Device" or
   "Mass Storage Device" etc.
