G'day Jim.
Did you receive the following?
I tried running "./drivers/nutdrv_qx -a ups1 -d1 -DDDDDD -x subdriver=hunnox" after building directly after
./configure --with-all --with-cgi --with-usb=libusb-1.0 --with-modbus=no --with-gpio=no --with-snmp=no
The output is the the attachment. Doesn't look good.
(I added the three =no bits to configure options because I couldn't find the relevant dependencies.)
Cheers,
Stephen

> but on another, NUT v2.8.2.1 along with `nut_libusb_open get iProduct failed, retrying` indicates that maybe this is a device with botched retrieval of language-specific strings, so we get part of that reply and the rest is seen by USB layer as garbage when asking for Q1. Maybe. At least, the part about iProduct, iVendor, possibly iSerial was solved about a year ago - so trying a newer NUT version can help.

If yes, you can go on about installing that build over the packaged version; if no, not much of a change for the existing system (except added build dependency prerequisite packages).
