Some more data: it appears that the usbfs flooding is a side effect of 
manually stopping upsd after this:

Feb 24 20:44:35 pve upsd[24581]: Data for UPS [idg800] is stale - check 
driver
Feb 24 20:44:36 pve upsmon[24615]: Poll UPS [idg800 at localhost] failed - 
Data stale
Feb 24 20:44:36 pve upsmon[24615]: Communications with UPS 
idg800 at localhost lost
Feb 24 20:44:41 pve upsmon[24615]: Poll UPS [idg800 at localhost] failed - 
Data stale
Feb 24 20:45:01  upsmon[24615]: last message repeated 3 times
Feb 24 20:45:01 pve upsmon[24615]: Poll UPS [idg800 at localhost] failed - 
Data stale

The riello_usb is not terminated when upsd is stopped, and starts 
flooding. It is possible to kill it ony with a SIGKILL.
