Ippon Smart Winner 1000 USB

Greetings,

I can't get my UPS to work with nut. I'm not pretty sure that it was a bug in NUT but I'll report it anyway. Thank you for your analysis!

Repoducibility:

100%

Actual results:

`# /usr/sbin/nutdrv_qx -a ismw1000_nutdrv_s`

Network UPS Tools - Generic Q* USB/Serial driver 0.06 (2.7.2)
USB communication driver 0.32

`# /usr/sbin/blazer_usb -a ismw1000_blazer_s`

Network UPS Tools - Megatec/Q1 protocol USB driver 0.11 (2.7.2)
No supported UPS detected

Expected results:

`# /usr/sbin/nutdrv_qx -a ismw1000_nutdrv_s`

Network UPS Tools - Generic Q* USB/Serial driver 0.06 (2.7.2)

I've also tried to use two other USB<->USB-AB cables with no success.

Workaround

Serial connection with blazer_ser works fine but I need GPIO for other purposes.

Did you completely power down the UPS after testing the serial connection? Many UPSes cannot switch between USB and serial on-the-fly.

Vlad1mir-D commented 9 years ago

Yes, I've tried to power off UPS completely without any success.

I assume the serial driver detected the megatec protocol variant?

Is this using libusb 1.0.x with libusb-compat? Most of the testing has been done with libusb-0.1.

Maybe @zykh has some other debugging ideas.

Vlad1mir-D commented 9 years ago

Accordings to libusb package description [1] it was libusb 1.0.x:

This package provides a way for applications to access USB devices. Legacy libusb-0.1 is no longer supported by upstream, therefore content of this package was replaced by libusb-compat. It provides compatibility layer allowing applications written for libusb-0.1 to work with libusb-1.0.

But I'm not really sure because in Fedora it could be virtually anything and only maintainer knows the truth.

Here is the build logs of packages that I was using:

Which OS would you recommend to test my UPS with (only package-based distribs please)?

And answer to your question: yes, UPS uses megatec serial protocol. I don't know exact difference between Q1 and megatec but it works with megatec.

Here is the build logs of packages that I was using:

nut-2.7.2-1.fc20.armv6hl libusb-0.1.5-3.fc20.armv6hl The "libusb-0.1.5" log does mention libusb-compat. I am not saying that it won't work, just that it is an extra layer of complexity. Which OS would you recommend to test my UPS with (only package-based distribs please)?

My personal preference would be Debian or Ubuntu (they still have libusb-0.1 as a separate library from libusb-compat), but even with Fedora it should be possible - it just might involve rebuilding the NUT package from source.

"megatec" uses some sort of "Q1" commands to query UPS status, but I think things are slightly different over USB. @zykh is much more familiar with this than I am.
