Win7 guest high speed usb

[rdl_42]

guest: Win7 Pro x64 sp1
virtualbox: 4.0.16
host: ubuntu 10.04

Problem:

All of my USB devices connect to the Win7 full speed hub. In Win7 device manager, I see two USB Root Hubs, both with 8 ports available. One is operating at full speed, the other at high speed. All of my devices connect to the full speed hub.

I have a 2.0 high speed device that I really need to operate at high speed. When I plug it in, windows even gives me a message that the device can perform faster, and should be connected to a USB 2.0 high speed port.

How do I get the device to connect to one of the ports on the high speed root hub?

Thanks for any help you can offer.

You installed the extension pack, yes?

Yes, extension pack installed. Device is claimed by VB when plugged in, and goes right to the win7 guest.

Forget all about USB high speed in the guest.

Have tested the speed with an external harddisk and can achieve a 5MB throughput - on the host the speed is above 20MB.

Were you able to connect to a guest high speed root hub?
