GPIB-USB-A malfunction after connection to old instrument

[cleat]

I connected a Solartron 1286 potentiostat (made in mid-80's) to my GPIB-USB-A interface, and it seems to have damaged my interface. I can install the GPIB-USB-A just fine, but when I try to search for instruments, the search time seems infinite. Are there warnings issued about the USB-A model regarding connecting to older instruments? Has anybody encountered this behavior before?

There is no known issues with GPIB-USB-A with your particular instrument and I know people have uses this USB-GPIB interface with older instruments without a problem.

It does not seem like there is a problem with interface if you could install the driver fine. You can use NI-SPY to take a SPY capture when "Scanning for instrument", this should give you more info on what was wrong. Also make sure your instrument is still functioning correctly; install the latest NI4882 driver (ver 2.3); and try to connect the instrument with a different cable, etc.
