Comment 10 for bug 645211

I checked my server again - indeed lsusb still shows the USB 2.0 device at the same time as the USB HDD.

The USB 2.0 controller disappearing on my client's server got me suspicious to an additional observation which I think might be related. Our backups are taking an EXTREMELY long time to complete. It is as if these USB 2.0 HDD's are actually connecting via USB 1.1 on Ubuntu 10.04 whereas on Ubuntu 9.10 and 9.04 there was no need to run additional commands and performance was snappy.

Backups usually took around an hour. The client's backup has been running for about 9 hours already and has only backed up 29GB of around 125GB.

It certainly smells like it is operating with a USB 1.1 connection to me.

Any clues as to why 10.04 is causing such difficulties? This is quite unacceptable... a real show stopper. I am probably going to have a screaming client in the morning when the backup is STILL running and they need to being the weeks tasks... probably scream to back level their server to Ubuntu 9.10, which is quite impossible.

Suggestions please?
