Linux Firmware Keyspan USB to Serial


Just wanted to share the difficult to find firmware that works between Linux and the awesome Keyspan USB to Serial devices.  I love these old Keyspan devices!  Anyways, here is the ‘dmesg’ signature for your perusal.

New USB device found, idVendor=06cd, idProduct=012a
New USB device strings: Mfr=1, Product=2, SerialNumber=0
Product: Keyspan USA-49WLC
Manufacturer: Keyspan, a division of InnoSys Inc.

On Debian 6, “squeeze”, and on Ubuntu images I simply copy the “keyspan.zip” file to the /lib/firmware/ folder, uncompress it and plug back in the device.  Everything works like a champ from that point on.

Firmware included for:

keyspan/mpr.fw
keyspan/usa18x.fw
keyspan/usa19.fw
keyspan/usa19qi.fw
keyspan/usa19qw.fw
keyspan/usa19w.fw
keyspan/usa28.fw
keyspan/usa28xa.fw
keyspan/usa28xb.fw
keyspan/usa28x.fw
keyspan/usa49w.fw
keyspan/usa49wlc.fw

Happy coding!

    Thanks a million!! I have been trying to add a serial port to my raspberry pi without success , then i found some old keyspan dongles (usa-19). Doing what you say above I now see ttyUSB0 and the RPI now can talk to my radio

    Thanks again

    Dave

    I do not know if it’s just me or if everyone else encountering problems with your blog. It appears as if some of the text on your content are running off the screen. Can somebody else please comment and let me know if this is happening to them too? This may be a issue with my internet browser because I’ve had this happen previously.
    Appreciate it

    Hey there. Thanks for this, I have downloaded it unzipped it into the firmware library for my raspberry pi and still my keyspan 19hs does not work.

    I found a link to a driver that goes along with the firmware, but I don’t know how to compile it or how to or where to put it. Any help would be appriciated.

    Thanks,
    Guy

    The keyspan and any that I can find usb to serial port only seems to run on one of the two usb ports on the raspberry pi itself. This works great, if you have the usb > serial converter plugged into one of those two ports.

    I can’t figure out how to get the usb to serial to work on a hub with the raspberry pi no matter what I do. Anyone got any ideas?

    Thanks,
    Guy

    Thanks! Saved me a lot of time to remember how this worked 🙂

    Worked for me too on a Raspberry Pi model B using a powered hub. I didn’t try without a hub since the pi is so sensitive to current load on the USB. Thanks!

    Thanks for this. Today I was able to get an old Keyspan USA-19 recognized by a RPi2 under the latest raspian OS.

    Trying to get a USA-19hs to work with a Raspberry pi. I unzipped the file, and put the drivers in the lib/firmware directory. reboot still will not give me a usb tty entry.

    Thanks for posting. I plugged my Keyspan USA-19HS into my Ubuntu 20.10 Lenovo X1 laptop, and I don’t see any firmware message in my console log. Perhaps as a result, attempts to set parity or stop bits via pyserial or stty seem ineffective. All I get in the logs when plugging in the Keyspan is:

    Anyone have any ideas why the firmware might not be loading?
