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....

Straightforward regression, most serious.  Thanks for reporting it.

I don't know much of anything about usb-serial, but I'll take a whack at 
it. Could you enable debug for that driver, launch apcupsd, and report 
any intersting messages that show up in dmesg? I'd be especially 
interested in any "Not setting..." or "Not writing..." messages, because 
some critical-looking code for baud rate setting and similar became 
conditional in 2.6.22.1 whereas it was always executed before. Apcupsd 
is going to be rather unhappy if the baud rate doesn't change when it 
asks. The debug should show if the these operations are being ignored on 
your hw.

Yup, there's what I expected. Not setting the baud rate and not writing 
status registers is unlikely to produce working results. This 9600 must 
be the default setting being applied.

Here's apcupsd trying to set 2400 baud.

Please try the attached patch (against 2.6.22.1). This will allow 
writing to the baud rate and MCR/LCR registers on non-EPIC adapters. I 
suspect the previous code was a copy-paste error.

Adam,

Yep..... That did it....

Thank You Very Much for your Super Quick Fix......
