Hi guys. I've got a pain in the ass problem. I've googled it, searched the archives for it, all sorts. I took yesterday to install arjanv 2.6.4 kernel on my Dell 5100 Laptop. I've installed a vanilla Kernel 2.6.4 on my desktop so I knew faguely that things should be ok. I followed the guide: http://www.freax.be/wiki/index.php/Fedora%20core%201%20with%20kernel%202.6-test Which all went smoothly. However I cannot get USB to function. The guide mentions adding: "alias usb-controller ehci-hcd alias usb-controller1 uhci-hcd" to modprobe.conf (Yes I've got USB2). Yet it does not work on a reboot. If I manually type: "sudo /sbin/modprobe uhci-hcd" then USB springs to life. More importantly my USB mouse works. Whats with that? Why does the /sbin/modprobe work but the modprobe.conf not? Cheers for any help. Adam
