Hi,
After the removal of the ums and ukbd devices from the kernel, a lot more
uhid devices showed up in /dev:
# dmesg | grep uhid
uhid0: <Logitech USB Receiver, class 0/0, rev 2.00/57.01, addr 3> on usbus4
uhid1: <Logitech USB Receiver, class 0/0, rev 2.00/57.01, addr 3> on usbus4
uhid2: <Apple Internal Keyboard> on usbus0
uhid3: <Touchpad> on usbus0
uhid4: <Apple Internal Keyboard> on usbus0
uhid5: <Apple Computer, Inc. IR Receiver, class 0/0, rev 2.00/1.10, addr 2> on usbus2
uhid6: <Apple Computer product 0x1000, class 0/0, rev 2.00/19.65, addr 2> on usbus3
uhid7: <Apple Computer product 0x1000, class 0/0, rev 2.00/19.65, addr 2> on usbus3
The dump for uhid2, uhid3 and uhid4 is shown below.
