[Nut-upsuser] How do I get the richcomm_usb driver - to work !

[Iain Simpson]

Thanks for suggestions

I've attached (con) listings of 'lsusb' & 'ls-lR /proc/bus/usb'
everything looks OK with  'root:root' & '-rw-rw-rw-'
(ups is 0925:1234)
when
'sudo /lib/nut/richcomm_usb -D -a vix2120 -u root' was run
I got
 >Network UPS Tools - Richcomm dry-contact to USB driver 0.04 (2.6.2)
 >Warning: This is an experimental driver.
 >Some features may not function correctly.

if I manually created '/var/run/nut'
and reran - it ran (as per attached) until ^C

I then ran 'sudo upsdrvctl -D -u root start' and it ran :

 >sudo upsdrvctl -u root start
 >Network UPS Tools - UPS driver controller 2.6.1
 >Network UPS Tools - Richcomm dry-contact to USB driver 0.04 (2.6.2)

It also responded if I disconnected the usb cable.

so it seems that permissions are the cause - but where?
(/etc/nut has owner:group  nut:root)



I don't think it is relevent but I had originally installed 2.6.1 from 
'Debian' (without richcomm_usb) and then built 2.6.2 as per Arnaud's 
instructions - just copying   ...nut/drivers/richcomm_usb to /lib/nut
(not nut/drivers/.libs/richcomm_usb to /lib/nut - drivers/.libs was 
empty) I didn't overwrite anything else.

Hope this helps

As I said - I don't have a feel for what's involved yet - still reading 
the manual.

Thanks
Iain
