So far, only the GPD-2303S is supported and tested. Adding support for the other devices should be relatively easy for someone with hardware access, though. Patches welcome!
Hardware
There was two hardware revisions (versions) of these units released. Model numbes did not change so it is difficult to determine whether unit is the "old" or "new" hardware revision. At least on GPD-3303S, there is slight change to unit front panels; older units have slight space in output jacks between "CH1" and "FIXED" channel, while newer units have even spacing.
It would appear that older hardware revision units have firmware version < v2.00, but this has not been confirmed. Base on anecdotal evidence only.
Protocol
