|We have three different stations for running tests where we need to log temperature vs. time. The computer can handle tracking multiple tests even though we can only set them up one at a time (in LabView). We had this working when we were using PS2 keyboards and mice (those units are still in place but non-functional). That setup used "Y-Key" and "Y-Mouse" adapters.|
It's interesting to note, when I plug the mice into the end of the long cable runs, the optical laser lights and the computer recognizes them as mice but does not register the input (the cursor doesn't move).
So the next logical step is to plug both secondary keyboards / mice into a powered USB hub that then plugs into one USB port on the computer? These two keyboards have two USB ports on them. I've got each mouse plugged into one of those ports on each keyboard (trying to minimize the number of cables we'd have to run).
Come to think of it, I'll try connecting the secondary keyboard / mice setups directly to the USB ports on the computer to see if that's the issue. If it is, a powered USB hub may be the answer.
