Hi,
I recently upgraded form OpenSuSE 10.3 to 11.1. In 10.3 I was very happily using an external DVD burner with k3b. However, if I try to use the very same burner in 11.1, k3b keeps on resetting the USB bus (or so it seems). In dmesg, the following output keeps on reappearing when inserting blank media in the drive while k3b is running:
Code:

If I write a disk from the command-line using growisofs, everything works fine, so I presume the burner itself does not have any issues.
Is there perhaps anyone out there who knows how to fix this issue? Any help would be greatly appreciated, as this is really annoying.
