Driver nutdrv_qx not working with Green Cell UPS04 but blazer_usb works
I have a new Green Cell Uninterruptible Power Supply UPS 1500VA 900W with LCD Display | EU VERSION aka. UPS04
# nut-scanner -U
Scanning USB bus.
[nutdev1]
driver = "nutdrv_qx"
port = "auto"
vendorid = "0001"
productid = "0000"
product = "MEC0003"
vendor = "MEC"
bus = "003"
Syslog reports:

When I switch to the blazer_usb driver it looks good and no problems are repoted in syslog:

I am reporting this, because the driver blazer_usb has been declared deprecated, but the successor nutdrv_qx is not working correctly for me.
nut-driver@nutdev1[9745]: Please note that this driver is deprecated and will not receive
nut-driver@nutdev1[9745]: new development. If it works for managing your devices - fine,
nut-driver@nutdev1[9745]: but if you are running it to try setting up a new device, please
nut-driver@nutdev1[9745]: consider the newer nutdrv_qx instead, which should handle all 'Qx'
nut-driver@nutdev1[9745]: protocol variants for NUT. (Please also report if your device works
nut-driver@nutdev1[9745]: with this driver, but nutdrv_qx would not actually support it with
nut-driver@nutdev1[9745]: any subdriver!)
Thanks for the highlight. I think there were some fixes merged for these drivers after 2.8.0 release, so if you'd have a chance to build and test the current codebase (whether the issue remains or got solved), it would be helpful.
Note that you are not required to install the test build over your packaged system just for testing (you can do so if you like the results though).
