could be that the USB bandwidth is not enough. If you are using a hub with both devices attached to it, there may not be bandwidth. You should plug one-or-the-other directly into another port on your computer.
If you still have the problem, i'd guess its a software issue (that the drivers are conflicting with one-another.
EDIT: doing a little more thinking, many motherboards use the same USB controller for all of the ports on the back of ther motherboard. Most motherboards also provide headers for front pannel USB ports, and or back plate (pci slot covers). Those normally have their own USB controller.... hope that made sense
