Comment 570 for bug 88746

I've also got this problem with a Freecom 160Gb USB drive Model (SSJABA), known as the Freecom Mobile Drive XXS, it is USB2.

If it is correctly detected by Karmic (also an issue with earlier versions of Ubuntu), it is very slow in reading and writing files (USB 1.1 Speed rather than USB2) when compared to a 80Gb Buffalo MiniStation USB disk I also have.

I've experienced problems on some NEC, VIA (all), and Alcor USB2 controller chipsets, although with Intel I've not had a problem but this is probably because my only Intel USB controller is USB1.1!

Dropping back to USB1.1 drivers fixes the problem but is unworkable with high capacity devices.
