Can this computer boot from USB?

Are those usb ports all failed? or are you trying to boot from USB drive or media and it fails?

All the USB ports are not functioning
USB devices are detected as unknown in Windows, even with a fresh install.  USB is not detected via bootable CDs & computer does not boot off of boot USB Flash media.
Also, ExpressCard to USB 2.0 Controller gives the same result.  At least two of these cards rely on the on-board USB 2.0 Controller to function

Which windows OS are you running?
You can test the USB outside of windows by running a bootable live cd like knoppix.
If the USB ports work in knoppix then you may need to reinstall windows.
If the USB ports do not work in knoppix, then the motherboard will need to be replaced.

USB does not work off of knoppix, even with ExpressCard to USB 2.0 Adapter.  Is there an ExpressCard USB 2.0 Adapter that does not utilize the on-board USB controller?

MarkCommented:
No, the 2 flavors of express card slot in laptops are either run from the PCI express bus, or the USB 2.0 controller. Yours seem to be USB controlled.
Do any express cards other than the usb adapter type work?

Yes, an ExpressCard to Cardbus Adapter with a Cardbus to USB 2.0 Adapter worked normally
