Subject: [PATCH] hantek-6xxx: Update driver to use the USB product version
 field.

We now require the use of the latest fx2lafw firmware which uses the
same USB VID/PID (1D50:608E) for the Hantek 6022BE and the variants
and rebadges of that device (e.g. the SainSmart DDS120).

The variants can be distinguished via the USB product version field.
