Unfortunatelly no. uhid merely emulates what a device can do, and HID is
a convention. So if we were to have a special case to PS3 controllers,
we would then start having to maintain an endless list of quirks when
the issue is *not* in uhid, but in the processing of the device after
(maybe in hid-core?).
