Sure, it is /dev/ttyUSB0 via cypress_m8 kernel driver.
This is my ups.conf:
 [ups]
    driver = powercom
    port = /dev/ttyUSB0
    type = "USB"
    modelname = BNT-800AP

This code originaly was writen for Imperial series, but BNT also have
ProductId 0x0002, so I test it and found it`s workable.
This is lsusb -v output from my BNT-800AP:

bInterfaceClass is set to HID, but usbhid driver does not works (it`s
tested).

I never seen Powercom devices with USB and different settings. It looks
like they are too lazy for programming device for other ProductId.
But, with Powercom nobody can`t be sure completly.
