USB doesn't work in xp guest

[jpxsat]

Hi:

Just installed XP under windows 7 to get to work Sonic Stage for Sony Walkman... everything works perfect until i plug the usb device... it doesn't work!! Installed guest additions, USB activated (strengely, the sony walkman device doesn't appear in the list before the machine starts). When the machine is running, i go to the below-window-menu and right click in the usb image to connect the sony walkman, and the following error appears: ​http://img259.imageshack.us/img259/8932/virtualbug.png

I think that this other one is the same error for another person: ​http://foros.softonic.com/hardware/usb-virtualbox-86351 And the bug is: ​http://img530.imageshack.us/img530/6836/errorgj6.jpg

Note that the program "Sonic Stage" isn't yet installed, it's only a question of windows not 'seeing' the usb device.
