Nut upsdev - Jun 2008 - megatec_usb not detecting UPS

Hoi all,

First of all thanks for all the great work on NUT.

I have two identical Socomec UPS Netys 1000PE. One is connected to an
Ubuntu Hardy 64bit system and is detected just fine by the driver
(v1.5.9), see below. The other one is connected to a Debian Etch 32bit
system and is not detected by the driver (v1.5.9), see below.

Would you have any idea how I could further debug this issue? Could it
be the difference between USB1.x and USB2.0?

Any help is much appreciated.

Jan

possibly due to the NUT version difference.
You should be running a patched 2.2.1 on HH and a 2.0.4 on Etch.
iirc, there was a fix for your problem. So your best chance is to get a
backport for Etch...
