KInfoCenter reports no USB Devices


I've tried a number of things to get my USB ports running, but yet they don't show up in KInfoCenter. Originally, I discovered this when I tried to install my printer / all-in-one, but I have also determined my USB flash drive (SanDisk Cruzer Titanium) doesn't work either. The LED flashes when it's plugged in, but doesn't stay lit like it should - nor does the computer recognize it. This is all very strange, because the machine recognized a USB keyboard and mouse when I was using them (I've since switched to PS/2 style for both).

I'm running Mepis 7.0 on a Compaq Presario SR1224NX.

From dmesg:
Linux version 2.6.22-1-mepis-smp (root@mepis-pro) (gcc version 4.1.2 20061115 (prerelease) (Debian 4.1.1-21)) #1 SMP PREEMPT Mon Feb 18 21:44:02 EST 2008

Also from dmesg:
root@mepis1:~# dmesg|grep usb
Kernel command line: root=/dev/sda1 nomce quiet splash vga=normal nousb resume=/dev/sda2
usbcore: USB support disabled
usbmon: debugfs is not available
ndiswrapper (register_devices:655): couldn't register usb driver: -19

Contents of /etc/fstab:

Anybody have any clues on how to get my USB ports recognized and working?

Found the answer

I kept searching, and figured the 'nousb' entry in the boot options was causing the problem. I edited /boot/grub/menu.lst and removed 'nousb' from the boot options and the problem was solved.

I've been able to get my flash drive recognized and read the files and, while I've installed my Epson Stylus CX5200 printer, I still haven't been able to print.
