I've done a bit of reading and found that my current device, D-Link WUA-2340 rA, is likely not going to work for what I need in BT5. Before I go spend money on something else, I'd to just get a confirmation that its not going to be compatible.

USB devices (generic detection):
Bus 001 Device 002: ID 07d1:3a08 D-Link System WUA-2340 RangeBooster G Adapter(Rev.A)
(no firmware) [Atheros AR5523]
If this is for sure not going to work, i'm looking at the Rosewill RNX-N250UBE (RNWD-11006). From what I can tell this is using the Realtek RTL8192CU chipset and has driver support for Linux Kernel 2.6x. Is this device going to work natively or at least be compatible with most/all BT5 applications? If not, what would be something else that is guaranteed to work for about the same price?
