I've been running WinXP on VirtualBox for a couple of years.

Primarily to debug with AVRStudio using JTAGice-mkII.

It's been the opposite experience here, USB functionality of the JTAG emulator 
has been flawless. Even when installing drivers in the guest win32 environment. 
Changing the enable/disable check box has been identical to unplugging and 
replugging the hardware, causing windows to re-enumerate the device.

This is hosted on 64bit archlinux. Intel mobo, Core2 Quad with 8G RAM, I give 
1G to the VM. 
The emulator is plugged into a host controller along with the UPS, no hub. From 
lsusb:

Bus 004 Device 003: ID 051d:0002 American Power Conversion Uninterruptible 
Power Supply
Bus 004 Device 002: ID 03eb:2103 Atmel Corp. JTAG ICE mkII

I really have been amazed at how well it works.

Wireshark also does a great job, via debugfs, of displaying the USB 
communication between; AVStudio in emulation, and the JTAGice-mkII hardware. If 
anyone wanted to write drivers to run the mkII natively on linux it would be 
straightforward to monitor/analyse the interface. 

Another vote for VirtualBox...
