Recently I purchased a Sweex 1000 VA UPS, which apparently is not like
the Sweex that was already supported by Nut. This one has an USB
interface only...

Nothing really seemed to work, until I ran across this topic.
megatec_usb seems to do _something_ to it, which is more than I can
say of any of the other drivers I tried. However, it seems the
protocol this UPS uses is not yet supported.

Here is the output I got from megatec_usb:

# /usr/local/ups/bin/megatec_usb -DDDDD -x vendorid=0925 -x
productid=1234 -x subdriver=agiler /dev/hiddev0

I tried to do some reverse engineering myself, however I am a very
novice programmer so that didn't do a whole lot of good.

Does anyone have any idea where I could go from here?

Sorry for the delay, I was busy with my university exams.

Your patch should be fixed: driver fails to build.
Please test patches before sending them.
This line

+lakeview_usb_LDADD = $(LDADD_DRIVER) $(LIBUSB_LDFLAGS)

should be replaced with

+lakeview_usb_LDADD = $(LDADD_DRIVERS) $(LIBUSB_LDFLAGS)

Have you switched from nut_usb.c interface to libusb.c/libhid.c
as Peter proposed?
