Hi, I've got the ASUS N73SV laptop with an infra red usb receiver. When I boot with it connected I get usb ports frozen for 10-20 seconds i.e. my external keyboard/mouse are not working for a few seconds after system is completely loaded and shows gdm screen. In some cases usb ports don't unfreeze so only reboot helps. There a some debug info shown in the dmesg - see below. But in general IR remote works fine. Moreover - if I connect the receiver after the system is completely loaded - all works just fine. Bun "lsusb -v" hangs! No problems in dmesg though. Not sure if this is connected problem, but sometimes system hangs on shutdown, (frequently when ir receiver connected).
