It worked with the kernel before. Reproducible: Always Steps to Reproduce: 1.Connect adapter 2. 3. Actual Results: USB Adapter is not working. lsusb hangs. Expected Results: USB adapter should work.
Is this the fix? http://patchwork.kernel.org/patch/25845/
This should already be in the .27 kernel tree, can you try the latest kernel-of-the-day for 11.1 and let us know if the problem still happens?
I used kernel-pae-2.6.27.29-SLE11_BRANCH_20090803102631_a828f069 and get the attached crash. Is this the 11.1 kotd?

Hi Christian - Can you try the test packages at http://ftp.suse.com/pub/people/jeffm/suse/testpkgs/514022/11.1-i586/ ? I've added a patch that should fix that oops, but I'm not sure if it's a symptom of a bigger problem.
Sorry for the late reply. Was on vacation. I tried the kernel you mentioned in #5 and get the attached oops. IIRC there was an oops with the latest official kernel for openSUSE 11.1 as well. Will try now and report back.

The oops still happens because the current, released kernel (2.6.27.29-0.1) still does not have the patch referenced in #1. Using the associated kernel-source and adding that one-liner patch seems to fix the oops for now. Tested using the original /proc/config.gz and a pae kernel. Boots clean and my Keyspan boxes connect and disconnect cleanly. I have not used them heavily yet, however...
I've committed to the repo. It will be in the next update or the one following it.
We have just released a SLE11/openSUSE 11.1 kernel update fixing/mentioning this bugreport, which has the version 2.6.27.37-0.1.1.
