# The STLink on the Discovery has a USB ID 0483:3744 and presents itself
# as a mass storage (i.e. SCSI) device.  The SCSI emulation is signficantly
# broken, and the kernel spews error reports for a while until it is
# accepted.  Further problems are encountered when if it is automatically
# mounted.
