#25: Sun Nov 19 16:47:54 CET 2006 [EMAIL
PROTECTED]:/usr/obj/usr/src/sys/FANGORN i386
>Description:
The USB Wi-Spy spectrum analyzer from MetaGeek LLC [1] is currently
recognized by FreeBSD as a USB keyboard, thus preventing the
user-space tools [2] from attaching to the device using ugen(4) and
libusb.

[2] http://www.kismetwireless.net/wispy.shtml
>How-To-Repeat:
Plug in a MetaGeek LLC Wi-Spy device and notice the following entries in
dmesg:
Nov 19 16:37:23 fangorn kernel: ukbd0: MetaGeek Wi-Spy, rev 2.00/1.00, addr 2,
iclass 3/1
Nov 19 16:37:23 fangorn kernel: kbd2 at ukbd0
>Fix:
The patch below adds a UQ_KBD_IGNORE flag to usb_quirks.h, similar to
the UQ_HID_IGNORE flag.
The patch also adds the PID of the Wi-Spy device and utilizes the new
UQ_KBD_IGNORE flag to make ukbd(4) ignore this device, leaving it to
be handled by ugen(4):
Nov 19 17:04:28 fangorn kernel: ugen0: MetaGeek Wi-Spy, rev 2.00/1.00, addr 2
It would be nice if __FreeBSD_version in sys/param.h could be bumped
once this patch goes in. This will allow me to test for proper kernel
support in my upcoming port of the above mentioned wispy-tools.
The patch is againt RELENG_6 but applies cleanly to CURRENT.
