Dual keyboard dual language setup

I have two issues, I recently purchased an imicro usb spanish keyboard. I want to be able to use my internal laptop (dell latitude E6410) for english and an external keyboard for spanish. First off I can't get the external keyboard to be recignized correctly. Yesterday I updated my chipset and bios and got it working but when I tried to plug it in today it wasn't working again, I'm getting error code 34 in device manager. I checked the manufacturers website but couldn't find a driver, so I emailed the place I purchased it from and am waiting for a response. Any ideas on the driver issue would be appreceated. When it did work yesterday I changed my language settings and could get both keyboards to be english or spanish but not one of each, any help on how to set this up would be apprecated as well.
