The above seems to be a truncated output from the keyboard part of the
USB receiver. Apart from claiming to have keys that it doesn't, which is
rather common, I don't see any problems there.

Here we have the multimedia part of the thingy, most likely some kind of
a remote. And this is where the hid-input module gets quite confused.
First by usages from the Consumer page it doesn't understand (0045,
009c, 009d, 0209, 008d).
Second, by Logitech vendor usages (ffbc.*). This will be a bit harder,
and will need your cooperation. Please enable DEBUG in hid-core.c, too,
and check what usages from the ffbc page appear in your syslog/dmesg
when you press keys on the device.
Let's take a look in the specs (USB HID HUT 1.11):
0045: MenuRight
009c: NextChannel
009d: PrevChannel
0209: ApplicationControlProperties
008d: MediaSelectProgramGuide
I guess I'll need your help again to find out what these keys are
supposed to do and how they're marked on the device.

Apart from claiming to have several LEDs of the same type ("Generic
Indicator"), which the hid-input mapper correctly ignores, the mouse is
pretty normal.

And here comes a keyboard, claiming LEDs it likely doesn't have, and a
bunch of extra keys, too, but nothing too bad.

And the second part of the USB keyboard is pretty evil. It claims to
be a mouse with 64 buttons, a host of consumer page keys and other
controls.
