I changed the driver line in ups.conf to nutdrv_atcl_usb but still get
the below:

Thanks, yes (now :-} )
So at least the string language index issue is solved, it sees the
common "MEC0003" name.
In the log I see you also setting "subdriver=hunnox" which is not listed
in the HCL comments:
$ git grep -i digitech
data/driver.list.in <http://driver.list.in>:"DigiTECH" "ups" "2"
"Computer 650VA" "USB" "nutdrv_qx port=auto vendorid=0001
productid=0000 protocol=hunnox langid_fix=0x0409 novendor noscanlangid"
# https://github.com/networkupstools/nut/pull/638 <https://
github.com/networkupstools/nut/pull/638> caveats at https://github.com/
networkupstools/nut/issues/674 <https://github.com/networkupstools/nut/
issues/674> (may need longer pollinterval)
Parameter names are a bit messed up historically, "subdriver" in
nutdrv_qx refers to USB connection nuances (vs. serial which has no such
concept), and "protocol" is the actual variant of some dialect derived
from a Megatec Q<x> protocol.
It may be that the USB subdriver for hunnox is in fact not what digitech
wants, and that's why connection setup fails?
One other idea is to make a shell loop trying all protocols and
subdrivers until something returns a reasonable response. You can see
the values to loop over in help message of the driver.
Finally, there is a chance that they released a device not talking
Megatec but something else. You can try `nutdrv_atcl_usb` (at least it
also fits the no-name 0000:0001 IDs), or `usbhid-ups -s test -x
port=auto -x productid=0000 -x vendorid=0001 -DDDDDD -d1`
The I/O error message seems to come out of the blue, so NUT just has it
with little context... You can also try your chances with LIBUSB_DEBUG,
see https://github.com/networkupstools/nut/wiki/Changing-NUT-daemon-
debug-verbosity#nut-v283-and-newer <https://github.com/networkupstools/
nut/wiki/Changing-NUT-daemon-debug-verbosity#nut-v283-and-newer> for
details.
Hope this helps,
Jim Klimov
