[USBSTOR]

Browse source 
- Add a check at USBSTOR_FdoHandleStartDevice to make sure the device uses Bulk Transfers.
- Use macros for initializing the Urbs. The macros ensure that the proper fields of the URB are set correctly.
Fixes failing of getting device descriptor and getting devices BlockLength.
