It depends on what you mean by 'redirect'. If you mean using the new features of RDP 6 (in Vista for example) for transparent use of devices like usb cameras, scanners, printers etc, then no, rdesktop (and afaik no other linux rdp client) cannot do what you want. I'd have thought that sometime in the future it'll become available, but since it's only recently been added to the RDP protocol, the rdesktop developers will take a while to catch up.
However, if you're just wanting to mount a usb stick, then you can forward that to a server, and it'll appear as a network drive. But I'd have thought 'hotplugging' the device will be problematic to say the least.
