Nut upsdev - Feb 2006 - APC Smart-UPS 1000 RM USB problems with newhidups

I'm trying to use a rackmount Smart-UPS from APC with the USB connector, and
I'm running into some issues.  They seem to stem from the fact that the 
Report Descriptor is much larger than any other UPS I've seen (61939 bytes).
  Here is the quick fix that I put in libusb.c after getting the HID 
descriptor, and before getting the Report descriptor, which seems to work 
okay:
                        if (desc->wDescriptorLength > 4096) {
                                desc->wDescriptorLength = 4096;
                        }
I'm sure there is a better way to handle this.  I'm just wondering if
this
is okay to do, and if anyone had a better way to fix it.  Thanks!

You'll probably find that it's not really that big, and that lsusb gives
a
more realistic number (1040 is what it says here).

That's pretty much what I did too.  Cf. my posting to the nut-upsdev list
<200601061304.k06D4uWd011796@eden.inf.ed.ac.uk> about a month ago.

BTW, it might be useful to know what kernel you're running on your machine.
Ours are basically Linux 2.6.12-1.1381_FC3 variants with libusb-0.1.10a.
