    Anyone know how to get a Keyspan USA-28X USB to two port 8-pin serial adapter to work with a Raspberry Pi? It shows up under lsusb but says "no firmware." I'm guessing these needed to have firmware uploaded to them when they were plugged in?

    I found an 11 year old Github repo that has Keyspan firmware, but maybe it needs to be compiled in a new kernal?

    Anyone done this before?

    Update! Simply copy the *.fw files to /lib/firmware/keyspan/
