Nut upsdev - Sep 2007 - Powercom USB UPS is not support

Hi, fellow NUT gurus;

 

I am having a big issue with our new Powercom Imperial Digital UPS. The
UPS is come with a serial over USB port and plug into the usb port on
the computer. I am having problem to setup our fedora 7 linux machine
talks to the ups.  The kernel 2.6.22.1 seems to be able to detect the
ups is plug into one of its usb port. But it just couldn't establish a
connection with the UPS. I have attached the screen dump below. Could
you please help...... 



The all ups configure files are being configure. We are running
nut-2.2.0 version and have tried to use the newhid-ups mgetech-usb
drivers. I think we need to modify the powercom driver with a usb
version such powercom-usb.

It surely looks like it.

This is becoming a FAQ nowadays. :-)

A report descriptor of just 37 bytes is far to small for a HID Power
Device, so there is no chance that it will work with the usbhid-ups
driver. It maps exactly one Feature, Input, and Output report. You might
try your luck with linking powercom.c with megatec_usb.c in the same way
as megatec.c is linked with megatec_usb.c and see how you get along. As
a side note, megatec_usb.c should really be named serial_usb.c, since
the megatec protocol is dealt with in the megatec.c file.

Something like
> powercom_usb_SOURCES = powercom.c megatec_usb.c libusb.c
> powercom_usb_CFLAGS = $(AM_CFLAGS) $(LIBUSB_CFLAGS) -DMEGATEC_SUBDRV
> powercom_usb_LDADD = $(LDADD_DRIVERS) $(LIBUSB_LDFLAGS)
in Makefile.am. You'll need to run configure again and maybe you need to
make other changes to this file as well. Remember to specify '-x
vendorid=0d9f -x productid=0002' on the startup commandline for the
powercom_usb driver. Please let us know how you get along.
