USB Headset detected, but not being loaded as a USB audio device.

Question

Hey,
I just bought a Gigaware USB Premium Audio headset with Mic, and I'm currently trying to get it to work. It does show up under lsusb:
Bus 002 Device 004: ID 0d8c:0105 C-Media Electronics, Inc.
Bus 002 Device 003: ID 046d:c01e Logitech, Inc. MX518 Optical Mouse
Bus 002 Device 002: ID 06a3:8021 Saitek PLC
Bus 002 Device 001: ID 1d6b:0001
Bus 001 Device 001: ID 1d6b:0002
It's showing up as the C-Media Electionics, Inc. device. Unfortunately, for an unknown reason to me, it doesn't want to be set up as a sound card, as in DMESG:
generic-usb 0003:0D8C:0105.0004: input,hidraw3: USB HID v1.00 Device [C-Media Electronics Inc. USB Audio Device] on usb-0000:00:0b.0-5/input3
cannot find the slot for index 0 (range 0-1), error: -16
cannot create card instance 0
snd-usb-audio: probe of 2-5:1.0 failed with error -5
usbcore: registered new interface driver snd-usb-audio
As you can see, I get three different errors. I've googled all of these, but have come to no conclusion as to what they mean, or a solution to them.
Any helps much appreciated,
Alex

The format says Mac OS Extended.  All of the settings were set during the disk image restore process.  Even if I format the flash drive as extended journaled or some other format, all of these settings are reverted when I do the restore from the disk image.  I will just copy all of the information that disk utility has so that you can see it.
