[PATCH] HID: sony: disable descriptor fixup for FutureMax Dance Mat

Show all headers | View raw

From: Mikko Perttunen <mperttunen@nvidia.com>

The FutureMax Dance Mat claims to be a SixAxis controller
but breaks if descriptor fixups are applied. Detect the
device using its USB product string and disable fixups
when it is detected.
