If you can find it on their website, try installing the driver via the control panel if it is for an older os like 98/ME, etc... If not, i don't know exactly where one would find a driver that old. Have you attempted to google it?
How about this page from HP's site? I don't know which OS you're using, or I could have been more specific with the link.
P.S. I wouldn't expect much from HP support. I was having a problem with my laptop's card reader that was clearly hardware-related, and what did they tell me to do? "Full system recovery, setting the computer back to its factory-default software state"!
lol yea.. HP support is terrible for sure. Now that I think of it so are a lot of PC manufacturers support.
A great reason to join Tom's Hardware! With all the active members, we can address almost anything OEM tech support can short of providing an RMA.
Did that link in my previous post give you what you needed?
