Well I adjusted the volume as you pointed out, still no luck.
Currently I am thinking I might need to get the usbconfig command above 
to now work, but it gives a nondescript error.

tardis# usbconfig
ugen4.2: <product 0x08c9 vendor 0x046d> at usbus4, cfg=0 md=HOST 
spd=HIGH (480Mbps) pwr=ON

tardis# lsusb
Bus /dev/usb Device /dev/ugen4.2: ID 046d:08c9 Logitech, Inc. QuickCam 
Ultra Vision

tardis# usbconfig -d ugen4.2 do_request 0x22 0x01 0x100 0x86 0x03 0x80 
0xBB 0x00

I have looked at the man pages in trying to figure out exactly what the 
eight number sets after do-request are doing, thinking that I might have 
to adjust them for some reason. I am also starting to wonder if my 
camera mic will work with Skype.

I ran the mic test listed on the webcam site, .
tardis# dd if=/dev/dsp1.0 of=/dev/dsp0.0 bs=64
^C1073+0 records in
1073+0 records out
68672 bytes transferred in 8.571198 secs (8012 bytes/sec)

The test works, the mic picked me up and played it through the speakers, 
with some nasty loop feedback, but it did work.
