[Nut-upsuser] trouble with Cyber Power System CPS RS232 USB BRIDGE for UPS

[Jon Bendtsen]

Hi

Recently i bought a MicroDoWell BP50, and with it followed a USB 2  
serial
converter. When i plug it into my 2.6.19 kernel, dmesg shows

hiddev96: USB HID v1.10 Device [Cyber Power System CPS RS232 USB  
BRIDGE for UPS] on usb-0000:00:04.2-2
usbcore: registered new interface driver usbhid
drivers/usb/input/hid-core.c: v2.6:USB HID core driver


So, i figured i should use usbhid-ups, /etc/nut/ups.conf
[switch]
   driver = usbhid-ups
   port = auto

and then i ran the command
	 /lib/nut/usbhid-ups -DDDDDDDDDDDDDDDD -a switch


root at dksrv003:/etc/nut# /lib/nut/usbhid-ups -DDDDDDDDDDDDDDDD -a switch
Network UPS Tools: 0.28 USB communication driver 0.28 - core 0.30

The MicroDoWell BP50 only has a serial out, but i am using the serial  
cable that came
with the UPS. Unfortunately it is not very long, so having a USB  
extender cable i connected
the serial cable to the UPS and the USB2serial converter and then the  
extender cable and
into my server.
