For 802.15.4 USB hardware, there are two devices that I'm familiar with both based on the Atmel AT86RF231 transceiver: The RZUSB stick from Atmel and the family of USB transceivers from Dresden Electronik. Both devices will present themselves to the USB host as a ACM serial port, and they'll have some protocol that's similar to the top of the MLME and MCPS API in the IEEE 802.15.4 specification.
The Atmel RZUSB dongles are running an AVR processor with an AT86RF231 and a PCB antenna. However, I've found the RF performance to be quite terrible, and they'll struggle to get packets across my cubicle. The Dresden Electronik dongles have much better RF performance, and are running an Atmel SAM3S processor with either an AT86RF212 or an AT86RF231 and they use a small ceramic antenna. They do have pads on the board to add a u.FL connector if you're good with a soldering iron. We prefer to use these USB dongles for our 802.15.4 projects (although, we wound up rewriting the firmware and changing the serial protocol).
