USB problem

[ChristZhou]

The virtual machines with either Janpanese Win XP and Japanese Lubuntu can't detect the USB devices including my sensor nodes and my enbedded board except my mouse, although it seems that the devices have been captured by the filter. If I click the device captured but not detected, I get the informtion "the device is busy with a previous request".

On the other hand, I also installed the VMware as there another course needs it. Is the problem occurred by the conflict between the VMware and the VBox filters?
