OK. That usually means that the VM kernel doesn't see that the device is
disconnecting. You can check dmesg to be sure, but the Device numbers usually
increment the next time a USB device is plugged in.

Not sure how ESXi hands off the USB devices to the VMs, but is there a way to
verify that other VMs are not seeing the UPS as well? Even simply probing the
device (a la modemtools) will cause problems, especially if the USB-to-serial
converter usually shows up as /dev/ttyUSB0 before NUT drivers start.

> And the output of the /lib/nut/nutdrv_qx -a apollo-ups -DD 2>&1
command is the same as in the previous attachment. I truncated the
"before" log because it just carried on with the same output after the
broadcast notification that the UPS became unavailable (at 214.883342).

Hmm, that's odd.

I forgot to mention: be sure that there are no existing drivers running
('sudo killall blazer_usb' and 'sudo killall nutdrv_qx') before
starting the driver in debug mode.

Can you run it again with three "-D" flags, and let it go past the
point where upsd complains? The third "-D" will show all read and
write results, which should definitely be different when problems arise.

A: Because it messes up the order in which people normally read text.
Q: Why is top-posting such a bad thing?
