Have you tried googling like this:
http://www.google.com/search?hl=en&rlz=1G1GGLQ_ENUS300&q=LSI+Logic+Symbios+5372+6872&aq=f&aqi=&aql=&oq=&gs_rfai=
or like this:?
http://www.google.com/search?hl=en&rlz=1G1GGLQ_ENUS300&ei=DFDrS42WA8WqlAfew7GcBA&sa=X&oi=spell&resnum=0&ct=result&cd=1&ved=0CBEQBSgA&q=LSI+Logic+Symbios+5372+6872+Logic+Device+Spec+Cycle&spell=1
I believe there might sufficient information to obtain the driver here:
http://www.cs.fsu.edu/~baker/devices/lxr/http/source/linux/drivers/ieee1394/oui.db?v=2.6.11.8
This looks interesting from googlecode:
http://code.google.com/p/roboticsby/source/browse/trash/system+information+detection+module/video+card/pci_c_header.h?spec=svn5&r=5
And there is this:
*
http://swiss.ubuntuforums.org/showthread.php?t=1477438*
Have you tried:
dmesg | grep Lsi
dmesg | more
Get vendor and product code
Note if this is a usbserial device:
modprobe usbserial vendor=0x4348 product=0x5523
or
modprobe serial vendor=0x5372 product=0x6872
dmesg
Near the end, you should see verification blah that it loaded successfully:
or serial_generic #: loaded
serial: attached to blah
serial: registered new interface driver LSI
Note you might also try:
modprobe lsi
dmesg
See the full HowTo here:
http://linux.about.com/od/srl_howto/a/hwtsrl07t03.htm
Congratulations, your link is up! As much fun as you had doing this, there
is some chance you want to do this automatically in the future. Just add
this line:
serial vendor=0x5372 product=0x6872
to /etc/modules with the vendor and product numbers.
Now, you should have no problem using this device like a normal serial
port. Hurrah! [image: grinning smiley]
