I'm puzzled that lsusb does not show anything on my laptop, although at the moment I have for example a USB memory stick in it, which is working fine. Nor is there anything in /proc/bus/usb/ . I have three other computers on which lsusb works as expected. All the computers are running Fedora-3 with kernel 2.6.11 . I see the internal USB hub with lspci: 00:07.2 USB Controller: Intel Corp. 82371AB/EB/MB PIIX4 USB (rev 01) It doesn't really matter too much, but I'm wondering what the reason is. Any advice or suggestions gratefully received. -- Timothy Murphy e-mail (<80k only): tim /at/ birdsnest.maths.tcd.ie tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland
