Extpack usb 2 downgrades to usb 1 if device in usb 2 hub

Reported by: lyallp Owned by:
Priority: major Component: USB
Version: VirtualBox 4.0.0 Keywords: usb hub
Cc: Guest type: Windows
Host type: Linux

Description

Virtualbox 4.0.0 OSE with oracle extension pack will forward a USB 2 device (say a USB key) to the guest OS as USB 2, if it is plugged directly into the Linux Host. However, if the Device is plugged into a USB 2 HUB, the device is presented as USB 1.1. (Windows says the device can perform faster...)

Running on Intel i7 M 620 Linux Kernel 2.6.35 64 bit Distro: Gentoo (kernel version is actually 2.6.35-gentoo-r15)

Tested in both USB2 and USB3 ports.

Kernel config attached

This is the cause of the problem described  here. If I plug the ActivIdentity USB SIM directly into the Linux host, it is available, if I plug it into a HUB, it is not.
