I'll try to remember tomorrow, but I doubt it will say anything new. > Check dmesg for usb-related things from bootup.

The effect is quite bizarre & it was the gods who saved me : if I hadn't happened to plug the mouse into the neighbouring port, I could have spent days struggling to find out what was wrong & even taken the mobo back to the store as defective. Both Mageia -- installed from USB stick in a partition on the HDD -- & System Rescue show /dev/input/mouse0 after booting ; in the case of SR it does it before I enter the GUI via 'wizard'. They have no problem with the 2.0/1.1 port, but the Gentoo system as I've installed it don't show /dev/input/mouse0 from that port, but only if I plug the mouse into the 3.0/2.0 port. Someone suggested it is caused by a Kernel .config setting, which if enabled seems to force the system to look in the 3.0 port. Why it should do that doesn't make much sense : such upgrades are usually permissive, not restrictive. BTW there's no difference between 3.4.9 & 3.5.3 . >> That also suggests that if I plug a USB stick into those 2 back ports, >> it will give faster transfer speed ; the front ports are 2.0/1.1 . >> Is it safe to test that ? -- ie I don't want to ruin a stick. > Unless it is an actual USB 3.0 stick -- blue plug -- > with fast enough flash memory inside, > it won't make any difference as far as speed goes. > The connectors are physically different, but backwards compatible. > There is no danger in plugging in older USB devices into a USB 3.0 port. None has a blue plug, so they all must be 2.0 . -- ========================,,============================================ SUPPORT ___________//___, Philip Webb ELECTRIC /] [] [] [] [] []| Cities Centre, University of Toronto TRANSIT `-O----------O---' purslowatchassdotutorontodotca
