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!
