The driver will have "Cypress Wireless USB" listed in the device list.
The chips will look something like this:

and will have CYxxxxx as the part numbers. If you can get the FCC ID
number off the device, you can look it up on the FCCID database and
check the inside photos.

However, I wouldn't worry (much) about interference from WirelessUSB
devices (i.e. mice and keyboards). The AFH algorith used in Bluetooth
1.2 and 2.0 is also used for Wireless USB. See the description at:

Wireless USB listens before selecting a channel and moves if it hears
garbage from 802.11 or Bluetooth.

>- I'm buying 900mHz wireless headphones, they're OK right?

Yep. No interference to 2.4GHz.
