Hi, one maconlinux session with the excellent linux kernel usbmon support
later, and I have my G4 powerbook's bluetooth adapter working.
To recap: My new G4 powerbook has a bluetooth device that boots up in what
apppears to be a compatability mode - it looks exactly like an HID
keyboard/mouse device.
A special command sequence is sent to switch it into full bluetooth mode. When
this occurs the original HID device vanishes, and a new (bluetooth HID) USB
device appears on the bus with a different product ID.
The original thread is here:
http://sourceforge.net/mailarchive/message.php?msg_id=12532263
The attached patch adds the device to the hid-core quirks so that hid-core
ignores it.
Also attached is my userspace program to switch the device.. I think this
should be in the kernel somewhere, but I'm not sure where. The bluetooth USB
HID driver sounds most suitable - does anyone have any suggestions?
