ThinkPad Mini Dock Series 3 and ThinkPad Mini Dock Plus Series 3 USB
Symptom

After Suspend/Resume or Hibernation/Resume of the T400s System, a balloon warning will sometimes appear with the comment 'This device can perform faster'.

In this situation, the Operating System (Windows Vista or Windows XP) recognizes the USB-HUB in the ThinkPad Mini Dock Series 3 or the ThinkPad Mini Dock Plus Series 3 as a USB1.1 (12Mbps) device, but the HUB should be USB2.0 (480Mbps). The HUB will then work as USB1.1 speed.

This problem does not occur after hot attaching and Cold boot. The issue appears only after resume from Suspend/Hibernation.

Affected configuration
