Any ways, just > wanted to report in case someone might ggest that... Any suggestions > are welcome... Have also tried the anheng 2.6.37 and 2.6.38 kernels. Again no luck. BTW, I tried on a ia64 box, and the TU2-ET100 works really nice on it. I think my suspision upon broken USB controller is more than that.
