Greg/Peter/Al,

I've been using the edgeport 4 port USB to Serial Converter 
to monitor APC Smart UPS's via apcupsd for quite awhile on 
various Linux boxes.

I just upgraded to Kernel Version 2.6.22.1 from 2.6.20.6 on a 
couple of systems and both the edgeports stopped communicating.

I tried applying various patches, "PATCH 026/149" and "PATCH 082/149" 
and one by Alan Cox..  but they didn't fix the problem.

I copied the 2.6.20.6 edgeport module sources to the new 
2.6.22.1 tree and everything works again.

          linux/drivers/usb/serial/io_edgeport.c
          linux/drivers/usb/serial/io_edgeport.h
          linux/drivers/usb/serial/io_edgeport.mod.c
          linux/drivers/usb/serial/io_tables.h


I thought you guys ought to be aware of this....

                  Nick Pasich
