"In the "wibu 740.txt" log we see
"2022-01-12 11:42:19: Error updating port UMS" which has been
cropping up recently with V7.40 for certain combinations of Windows machines
and CmDongles operating in Mass Storage Device mode. Without a full CmDust log
we can't tell if your Series 2 dongle falls into this group, but it is a good
bet since that is their default mode."
Most likely switching it to Human Interface Device mode will solve the issue
without any further action needed.
Please connect the problematic dongle(s) to a known working PC and follow the
below steps after the device is recognized:
1. Open Command Prompt or Power Shell
2. Run the following command: cmu32 --hid
You should see a message like the one below telling you the change was applied.
Configuring CmContainer x-xxxxxxx:
Communication mode changed successfully.
Please replug your CmDongle to apply the changes.
Note that command will update all plugged in CodeMeter-Stick
devices.
