I have recently started having problems with my usb ports. First I tried to install a new multi-function Epson printer. The scanner part installed ok but the printer didn't seem to install. I had a lengthy discussion with the Epson help desk where we tried uninstalling the printer drivers and removing the usb ports via device manager. No luck. They recommended contacting the manufacturer.
Since then I've bought a Freecom mobile drive which works fine on several pc's but not the problem one. It just makes a funny clicking sound when you plug it in. I also had problems with another external hard drive which is connected to the firewire port. This was not being recognised at all, although it seems to be working all right at the moment.
I've tried restoring a known good backup of the operating system but this hasn't fixed the problem. Could this be a hardware problem? Is there anyway to diagnose it? Do I need to replace the motherboard?

Re: problems using usb ports
I assume these are the built in ports you are having trouble with.Do you have a terminal to install another usb port via a dongle It may be that the inner terminals of the usb receptacle are not making good contact (defective) If you have a junk board with same setup you might be able to desolder the port,and replace yours. I haven't had the occassion to try this yet, but it might work

I have the same problem...Epson does not work with a parallel to usb cable or adapter. If you still want to use this printer you will have to use the parallel port or change the interface on the printer to USB.
have you connected the printer's USB port to your CPU? If not, then do so. If after doing it, still your PC don't detect your printer, make sure you have a functional USB port. To check it, try using a USB Flash drive if it works with your PC. If it won't, you might have to "Enable" your USB at your BIOS.
assuming you properly installed the "printer driver".
disconnect the printer. check Printer & Faxes for printer icon(s) - delete print queue(s) and the printer icon(s). open device manager and go to Universal Serial Bus Controllers section.
now we check for connectivity: (treat the printer and scanner as separate devices)
connect the printer, USB Printing support must show up (also check Imaging Devices and the scanner must also show up)
IF USB Printing support shows, windows will create a printer icon in the Printers & Faxes, right click choose properties and print a test page. ELSE, it's the printer and request for a replacement if it is still within 1 year from the date of purchase
well i'm not sure waht is your issue,
but you can try to check this out
If you are using win 2000/xp/
and usb cable connection/interface
after you installed the drivers from the cd software or from epson website http://www.epson.com/cgi-bin/Store/support/SupportIndex.jsp
click on start>> control panel>> printers and faxes>> right click on the printer icon(epson stylus?)>> properties>> ports>> select usb001 virtual printer port for usb...
well... sory if i misunderstand you
Unplug the printer. After uninstalling the software make sure you delete the printer from Printers and Faxes!
Try plugging it up again(don't install back the software just as yet), the New device found pop up should come up! if it doesn't then it could be the USB cable / the USB ports on the PC or the USB interface on the card! If it does , put the cd in the drive and select Install Drivers automatically(if its pops up)
Also, Try using different USB ports if the new device pop up doesn't pop up!
Test the USB ports by using a regular USB device in the same port you are plugging the printer into!
A bad USB cable could be the issue but it can also be something else!
You'll need to verify that its the cable, what you can do is try it with a cable that you know is fully functional!
If you still don't get a response from the printer and everything else works(i.e. usb cable, usb ports) then it could be the USB interface on the printer! and you'll need to take it to a tech!
Hope this helps!!
