Firefox and nternet Explorer extremely slow on HP USB docking station

Symptom: You are using a notebook with Windows 7 x64 and a HP USB 2.0 Docking Station. Your IE9 and/or Firefox experience is dramatic.

Cause: The problem is not in the browser software but in the Display Link Driver.

With the USB docking station comes the driver 5.4, which has a very poor performance.

Resolution: Upgrade to latest Display Link Drivers directly from Display Link Inc. (as for 07/09/2011 is ver. 5.6) .
