[bug?] [powerpc] hid_logitech_dj: Wireless mouse does not work in xorg or gpm

Hi Nestor et al,

Huge Osvaldo Barrera writes, regarding a Logitech USB Receiver
(id 046d:c52b) attached to a PowerBook6,5 [1]:

My mouse does not seem to work, either with Xorg, or gpm.  It's a
Logitech Performance MX.

It works fine on -stable after a clean installation of the 6.0.4
netinst ISO, but does not work either on testing, or sid.

(For context: stable = 2.6.32.y, testing and sid = 3.2.y.)

It did not work a week ago, and does not work today either (so this
has been broken on both sid and testing for a week now).

[...]

When I installed stable and upgraded to testing, the device node
/dev/input/mouse1 did exist (mouse0 is the trackpad), but "cat
/dev/input/mouse1" showed no output when moving the mouse (mouse0
did when moving the trackpad). When doing a clean install of
testing, the device node mouse1 is never created.

After looking at the dmesg and lsusb, the device itself seems to be
detected, however, it does not work.

The mouse works fine on another linux-based computer (ArchLinux,
with kernel 3.3.2), so the mouse is not the issue.  I additionally
have another identical mouse, which exhibits the same behaviour (on
both computers).

He later clarified that the machine with ArchLinux was an amd64
machine.  So my first guess is that this might be an endianness issue
in the driver (hid_logitech_dj, which was a new driver introduced
during the 3.2 merge window).

Kernel log snippet, module list, and some other info are at [1].
Known problem?  Any hints for tracking this down?

Thanks,
Jonathan
