external USB Storage offlined and not usable - only in ubuntu kernels - not in gentoo / opensuse

[Michael Alzheimer]

if i attach a external USB-Storage Disk (usb3.0 disk) to my usb port (only 2), the disk get not regognized and be offlined.
Here are the Messages from "dmesg":

This happens ONLY with ubuntu Kernels (specially here 2.6.38-11-server #50-Ubuntu SMP), but also happens with ubuntu live CD.

Attaching the same disk to the same notebook but booted a self compiled gentoo linux (also 2.6.38) or a installed opensuse 11.4 the disk works perfectly as expected...

Furthermore attaching another usb2.0 disk to the usb 2.0 port on the notebook (with ubuntu-kernel) it gets only as usb 1.1 recognized and is extremly slow, of course.

As I remember I had similar problems under gentoo (a lot kernel versions ago) - fixed it by NOT compiling the {u,o,e}hci_hcd modules into the kernel - but compiling them as modules and loading them in (maybe?) special order.

Status changed to 'Confirmed' because the bug affects multiple users.

I faced the same problem.

Ubuntu 11.10 -> failed.
Ubuntu 11.04 -> failed.
Ubuntu 10.10 -> ok.

blacklisting the uas kernel module is for me the workaround. - then it works - i think might be a problem with the uas module?

root@k:~# more /etc/modprobe.d/blacklist.conf
# This file lists those modules which we don't want to be loaded by
# alias expansion, usually so some other driver will be loaded for the
# device instead.

blacklist uas

Aha! It worked!
Thanks.
