[Nut-upsdev] Megatec_USB on OpenBSD 4.3 - no input interrupt endpoint

Fri Sep 12 10:24:13 UTC 2008

Hi!

   I am trying to get an Atlantis-Land 1501 UPS to work under OpenBSD. 
The UPS works OK under Linux + megatec_usb driver+nut_2.2.2.

   What I get under OpenBSD is:

root at puffwall:~ # dmesg

Serial" rev 1.00/1.00 addr 2
uhidev0: no input interrupt endpoint

    This is the output of usbdevs (sorry, we have no lsusb ;-)

root at puffwall# usbdevs -dv

Serial(0x0000), UIS_ABLER(0x0001), rev 1.00
   uhidev0
 port 2 powered

    Since I was having no luck with the NUT package provided by OpenBSD 
(nut version is 2.2.1, using libusb-0.1.12), I downloaded and compiled 
the 2.2.2 version (which *does* support my UPS): here's what I get:

root at puffwall:~/nut-2.2.2 # drivers/megatec_usb  -a atlantisland -u _ups 
-DDDD

Andrey Lelikov (c) 2006, Alexander Gordeev (c) 2006-2007, Jon Gough (c) 2007

debug level is '4'
No appropriate HID device found
No supported devices found. Please check your device availability with 
'lsusb'
and make sure you have an up-to-date version of NUT. If this does not help,
try running the driver with at least 'vendorid' and 'subdriver' options
specified. Please refer to the man page for details about these options
(man 8 megatec_usb).
Please report your results to the NUT user's mailing list
<nut-upsuser at lists.alioth.debian.org>.

    And, finally, here's a clip of my ups.conf file:

[atlantisland]
    driver = usbhid_ups
    port = /dev/usb0
    desc = "Atlantis Land 1501"

   Please note I tried all possibile values for "port": /dev/uhid0, 
/dev/uhidev0 and /dev/usb0

   Under Linux (with the same UPS), I just point "port" to /dev/ttyUSB0, 
or whatever (I actually found it doesn't really matter, you can enter 
/dev/foobar) and the driver starts scanning:

I am always lost when dealing with USB, HID & Co., any help is welcome. 
Thanks in advance.
