sysutils/nut and an MGE Ellipse 1000 UPS

[Daniel O'Connor]

Hi,
I have an MGE UPS connected via USB and I am having trouble getting it 
to work.

I am trying the latest SVN trunk from the NUTdevs but I find it doesn't 
enumerate everything from the UPS properly, eg

[midget 21:10] ~/projects/nut-trunk >sudo /usr/local/libexec/nut/usbhid-ups -D -D -D -a mge
   6.238605     Path: UPS.PowerSummary.PresentStatus.Discharging, Type: Feature, ReportID: 0x01, Offset: 2,

   6.238627     Report[buf]: (2 bytes) => 01 13
   6.238647     Path: UPS.PowerSummary.PresentStatus.Charging, Type: Feature, ReportID: 0x01, Offset: 1, Size:

   6.238669     Report[buf]: (2 bytes) => 01 13
   6.238676     Path: UPS.PowerSummary.PresentStatus.BelowRemainingCapacityLimit, Type: Feature, ReportID:

 or..

  20.867648     libusb_get_report: Unknown error
  20.867744     Can't retrieve Report 0a: Input/output error
  22.618705     upsdrv_updateinfo...
  22.618729     Got to reconnect!

Sometimes it seems to work for a while, other times it won't even get the 
initial descriptor.

I tried setting LIBUSB_DEBUG but it didn't seem to produce any output.

I find that if I set 'pollonly' (ie disable interrupt pipe) it works
considerably better but still glitches not infrequently. (ie upsc reports 
stale data)
