riello_usb NPW1000 with serial to USB converter

[d1nuc0m]

Hi, this is a parallel to #2291 (haven't been able to replace the USB port yet...)

I'm using a Riello NPW1000 with a bad USB port, so I tried to connect it to the PC using a RS-232 to USB converter.

The adapter is reported by lsusb as ID 0403:6001 Future Technology Devices International, Ltd FT232 Serial (UART) IC and accessible as /dev/ttyUSB0

I tried to configure NUT to use the serial with this configuration:

[riellonpw1000_serial]
  driver = riello_ser
  port   = /dev/ttyUSB0
  user   = root

But the UPS is not detected:

$ sudo riello_ser -a riellonpw1000_serial -DDDDDD -d1

Just in case, some sanity-checks:

• do you have any other programs (screen, getty etc.) trying to use the /dev/ttyUSB0 as well?
  • Potentially, the riello_usb if it is also running? In fact, the nut-driver-enumerator might auto-create you instances of the service units to wrap the drivers, and those could also conflict with each other and command-line runs, see https://github.com/networkupstools/nut/wiki/nut%E2%80%90driver%E2%80%90enumerator-(NDE)
• are you sure there are no other ttyUSB's there? :)
• is the USB link to the UPS detached? (Some vendors/devices allow only one of USB/Serial links, if both are plugged)
  • ...and the port broken on the UPS side might impact this, e.g. think it is always connected?..
