Are there still some outstanding bug reports? I've seen a report that uhci can cause oopses when unloaded in an older SUSE enterprise kernel as memory is still being used by the host controller device after the module is unloaded from the system. At first glance I didn't find any patches that resolved the issue in mainline, but I might have missed them. If you are curious, I can dig up the bug report. thanks, greg k-h -- 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
