I think it's a USB Core problem, because if I attach my pvrusb2 I get the same as devsk, the firmware is not loaded and it's not working! If I then disconnect it, I can't use any USB devices anymore, because the USB connect or disconnect doesn't work anymore, the USB core seems to be locked. I have seen the problem in Ubuntu 8.10 beta and Mandriva2009, both using the 2.6.27 kernel. Made a bug report to Ubuntu kernel team a long time ago, but no luck yet, so maybe we will not be able to use our pvrusb2 devices in the upcoming Ubuntu 8.10 ;-( Regards Bent _______________________________________________ pvrusb2 mailing list [email protected] http://www.isely.net/cgi-bin/mailman/listinfo/pvrusb2
