What operating system are you using? If you are using ME (with which this is a common problem, of course with ME what isn't a common problem) your best solution is to install a different OS. To fully answer your question, more info is needed, such as OS, what is the exact message you are getting, and what are the devices?
My USB ports have stopped working. I have read thru various questions and tried the collective inputs that were suggested. All things (device mngr, diagnostics, etc.)say my hub root and controllers are fine, but when I try to use the items, I get a communication error stating that there is a USB problem. I have uninstalled/ reinstalled the devices and changed cables/ports to no avail. these items were working fine aweek ago and are still working fine when hooked up to another computer. help.....
