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.
