I am not sure what you mean.

There should be one copy of upsd, one copy of nutdrv_atcl_usb, and if you are using upsmon, two copies of that (one running as root, and an unprivileged one talking to upsd).

The "Device or resource busy" error can occur if you have more than one copy of nutdrv_atcl_usb, or if another program besides NUT is trying to control the UPS.

upsc requires upsd and the driver (nutdrv_atcl_usb) to be running. If upsd is not running, upsc will get "Connection refused".

upsmon also requires upsd and the driver. NOCOMM means no communication between upsmon and the UPS (via upsd). This is expected.

Yes, as mentioned in the startup banner:

"Warning: This is an experimental driver.
Some features may not function correctly."

It worked for Ariel, who provided the initial protocol traces: http://news.gmane.org/find-root.php?message_id=52B4C54E.1050106@ariwainer.com.ar

but there is certainly the possibility that other UPSes with that ID string are different. Dan also wrote a driver which talks to "ATCL FOR USB" devices, but with a different protocol:
