I successfully used my Keyspan USA-19QW USB-to-serial dongle back in
2007 running Ubuntu.



After several OS reinstalls, I am now on Debian Squeeze, but I am
having some problems getting it to work.



Is there some user error involved here or should I open a bug?



- After I plug in the USB-to-serial dongle (dmesg):

- No device file (/dev/ttyUSB0) is created:

$ ls -l /dev|grep -i usb

- According to:

http://wiki.debian.org/Firmware

keyspan/usa19qw.fw is in keyspan.ko
