I bought it 2 years ago to get ethernet onto a VERY old P2 system, anyways just sits and I never use it, so I put it in my WindowsXP and it reads it as a Realtek_RTL8150_USB_10_100_Fast_Ethernet_Adapter, but it is a generic CompUSA adapter really. SPECS:
AMD Athlon X2 4000 Brisbane oc'd 2.5ghz
Biostar GF7025-M2 (AM2) Mobo
1GB PC4200 DDR2
NVIDIA GeForce 7025 (north) / nForce 630a (south) CHIPSETS
Foxconn Geforce 8400GS PCIe
Realtek ALC662 6-Channel HD Audio
Realtek RTL8201N - 10/100 PHY

I am running Jas 10.4 but Im about to run Leo today, but natively I dont get LAN or Audio and ANY osx build 10.4 or 10.5, but I was figuring it would be easier to get the little USB thumb adapter to work, than my onboard LAN, I cant get anything to work right, just the basic installation
