Nut upsuser - Oct 2008 - Megatec_USB on OpenBSD 4.3 - again...

Hello again!

   Thanks to the precious help from Henning Brauer, I managed to solve
an issue with my UPS (a rebranded UPS speaking in Ablerex-ese over USB).
Under OpenBSD 4.3, the UPS was claimed by HID. Now that I recompiled the
kernel, adding a USB_quirk, this is what I get when I insert the USB
cable:

ugen0 at uhub0 port 2 "UIS_ABLER USB to Serial" rev 1.00/1.00 addr 2

So far, so good (Henning confirmed this).

Trouble is, when I run megatec_usb:

root at puffwall:~/nut-2.2.2 # drivers/megatec_usb -u _ups -a atlantisland
-DDDDDD Network UPS Tools 2.2.2 - Megatec protocol driver 1.5.14
[megatec_usb]

Serial-over-USB transport layer for Megatec protocol driver
[megatec_usb]
Andrey Lelikov (c) 2006, Alexander Gordeev (c) 2006-2007, Jon Gough (c)
2007

debug level is '6'
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>.


This is my ups.conf:

[atlantisland]
    driver = megatec_usb
    port = /dev/tty00
    desc = "Atlantis Land 1501"

I tried, just in case, port = /dev/ugen0.00 but, as I have been pointed
before, this is irrelevant.

Here's the equivalent of a lsusb:
root at puffwall:~/nut-2.2.2 # usbdevs -vd
Controller /dev/usb0:
addr 1: full speed, self powered, config 1, UHCI root hub(0x0000),
VIA(0x1106), rev 1.00
  uhub0
 port 1 powered
 port 2 addr 2: low speed, power 100 mA, config 1, USB to
Serial(0x0000), UIS_ABLER(0x0001), rev 1.00
   ugen0


also made ugen r/w to user _nut, as suggested in a tutorial:
root at puffwall:~/nut-2.2.2 # ll /dev/ugen0*
crw-rw-rw-    1 root     wheel     63,   0 Jun  2 21:25 /dev/ugen0.00
crw-rw-rw-    1 root     wheel     63,   1 Jun  2 21:25 /dev/ugen0.01
crw-rw-rw-    1 root     wheel     63,   2 Jun  2 21:25 /dev/ugen0.02


I am a bit lost. Please note that I have the same UPS up and running
under Linux (same nut, 2.2.2), so I know it is supported. Thanks in
advance for any suggestions

Wait a minute, if OpenBSD claimed this device, chances are that it was  
providing a USB to serial port also. Usually these are called  
something like /dev/ttyUSB0 in Linux, I don't know what OpenBSD does  
with it. In that case, you should run the megatec driver on the serial  
port, not the megatec_usb driver.

The megatec_usb driver attempts to provide the bare functionality that  
is required for a USB to serial converter (when not supported by the  
kernel) and then uses the megatec driver core to speak to it. But if  
the first is already supported by the kernel (if it claims it, chances  
are that it is) there is no need for that.
