[Nut-upsuser] Mustek Powermust 600VA

  I'm having a hard time configuring a Mustek Powermust 600VA ups to
work via USB with nut. I read somewhere that nut works OK via the
rs232 cable, but unfortunately I don't have a COM port in my computer.
  The kernel detects the ups as an Xbox pad :) and loads the xpad
module. I tried running /lib/nut/megatec with different /dev/ttySx but
it displays megatec protocol UPS was not detected. 

This is what I get from lsusb -v:

How do I create an appropriate /dev/ttyS and is there a way to make
linux work with this ups?
