SolidTek ASK-3962 keyboard works but mouse doesn't [patch]

[Adam Bliss]

Hi there,

I bought a SolidTek ASK-3962 Keyboard/Mouse for use with my Home
Theatre PC.  The keyboard connects and works great with bluez 4.60 --
hooray!

However, the mouse does not work.  I traced this down to the subclass
the device reports when it connects.  It reports 0x40, while bluez
expects it to include 0x80 to be treated as a mouse.  I found this
patch to work great:

encrypt_completed, req);


(You can also do this with the old hidd program by passing "-b 192" to
force the subclass.)

I don't know if one-off hacks in device.c are the right way to solve
this problem -- I was "inspired" by the one-off patch in there already
for 054c:0268.  Let me know if there's a more appropriate way to fix
this, and I'll be happy to send in another patch.

Cheers,
