cannot enable usb port

I've been having problems getting my two usb ports to work on my relatively new server board. My usb hp printer worked after I loaded the usblp module in kernel 2.6, but now it has stopped working, yetagain. My usb stick also used to work, but now that doesn't work anymore either. The cable is NOT bad since I've had this printer working in the past.

hub 1-0:1.0: Cannot enable port 1. Maybe the USB cable is bad?
hub 2-0:1.0: Cannot enable port 2. Maybe the USB cable is bad?

My usb spec is 1.1, not 2.0; so the OHCI driver is correct.

My Google and LQ searches have returned few results.

Only thought it might be a kernel issue with one of the modules. Check the changelogs over at on current kernel and previous kernels that may have worked on if updated. I have had issues with USB back in 2.6.9 run. 2.6.8 worked 2.6.10 and greater worked. 2.6.9 did not work with some of my USB devices. If orginal kerenl is still present bootup with that and see if that works.
