USB keyboard, mouse, ethernet stop working after reinstall of FC2
 

I recently upgraded from FC1 to FC2 and had no problems except for an error window that now pops up after log-on ("Error activating XKB configuration. Probably internal X server problem.")

I installed the new kernel a couple days ago and as it had no effect on the error message, I decided to try to reinstall FC2, theorizing that something may have been corrupted during the original install.

Since reinstalling FC2, none of my USB devices are recognized: keyboard, mouse, or printer. In addition, my ethernet port has gone inactive and I cannot activate it.

I've tried booting with both old and new kernels, but nothing changes. I've also tried both enabling and disabling USB legacy in the BIOS settings.

Any suggestions?
