From what I can see these are USB bus resets happening for no reason. In

Hi, I'm highly disappointed of 12.1 and its kernel :-( Before openSUSE 11.4 it was basically impossible to print on my local HP USB printer for several years (back to 2007 or so). With openSUSE 11.4 it finally worked (always!). Now with 12.1 I got the very same issue as in the past. Therefore the main question: Is it possible to use the 11.4 kernel on 12.1 (even if only for testing purposes)? Second: What can I do to make openSUSE finally work with my printer? Below are the log messages when the error happens. the past people always claimed that some hardware is broken but I do not buy that argument as 11.4 demonstrated that it can just work with 100% same hardware. With luck I can print one page at the moment before the USB bus breaks and no single event like that happened with 11.4. Any pointers?
