Question: About USB Over RDP

[Jeffrey]

Hello, Everybody?
I have a question about USB over RDP. My host OS and guest OS are windows Server 2003. I have enabled VRDP with 1234 port, and have enabled USB controller with a USB devices filter whose property of remote is "any". When I plug an USB storage device in host, the guest OS inside the VM displays the USB storage device and everything is OK.

But now I want to use the VM with terminal. The terminal OS is
Windows XP. When I use RDP5.x to connect the VM, I can log in the guest OS inside the VM, but the USB storage device can't map from the client to VM.

How should I do?
