Comment 512 for bug 88746

Hello, I've bought an external hard disk casing, but I can't get it working under Ubuntu intrepid.

kernel version:

Linux stest 2.6.27-11-generic #1 SMP Wed Apr 1 20:53:41 UTC 2009 x86_64 GNU/Linux

output of dmesg after connecting the external hdd to my laptop, a Dell Latitude D820

I've also tried connecting it to a new computer with a Gigabyte GA-MA78GM-S2H mainboard.
--> doesn't work
And also with another computer, with a nForce based chipset, it doesn't work.
USB 1.1 mode works "fine" ( harddrive gets mounted, but is unusable slow)
