AOpen AX34 (B) need USB drivers. Acer is no help. First tell me they
don't have a B Motherboard but my work order ahs this on the list.
Then they told me a 4 in one to use and it didn't work. I am trying to
reconnect my printer (LEX X75)

You might try connecting the printer.  Then let windows try to find
the drivers. Use Start-->Setting--->control Panel---->add new
hardward.

USB drivers come with Windows.

IF I understand you question, then you know this ---- but just in case:

USB drivers are NOT printer specific.  That's why you can plug
anything into a USB port and away you go...  Now USB drivers come in
1.0 or 2.0.  It depends on the hardware within the computer.  I just
upgraded my machine to 2.0.  It took a new USB 2.0 card.  Office Depot
charged me $35 bucks for the card and software.  Easy to install if
you have an open slot.

Printer Drivers are specific.

I hope this helps.
