Hi Sarah, It seems most of the problems were fixed after I applied Clemens' USB audio patch and your stall and cycle-bit patches. There is still one crash, but it only occurs when connecting a SuperSpeed Isoc device, and only when using netconsole. I think that's probably unrelated to these patches. -- Paul -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
