I recently bought a new dell optiplex 790 pc that includes a amd radeon hd 6350 display adapter. I also have 6 plugable usb 2.0 adapters that i bought. I hooked them up to my older pc and they worked fine.
However i am having trouble hooking them up to my new dell pc. I can successfully get 1 to work correctly after installing all the drivers. But when i plug the 2nd one in, the 1st one disappears and neither of them get read.
