From what I've understood from the above, you're trying to use a PCI device with some kind of virtualization software (VMware, VBox, Parallels, etc...). If that's the case, then it won't work. Read the FAQ for more information.
EDIT: I re-read your post, it seems I misunderstood what you said. Sorry about that.
This page states that your wireless card's chipset works with BT3, so it should work with BT4. How are you running BT4? If you issue a "ifconfig -a" can you see your card? (Yes, I know it doesn't appear in lspci. Try it anyway.)
