Thanks for the super fast response!
After some unplugging and replugging, the scanner suddenly started working again.
I then tried two different cables, both worked on both scanners, on both usb c ports of the m1 powerbook.
The mini was recognized, the firmware is reported as the newest version, everything work very stable at the moment.
I really don’t understand what was going on, because for some hours after the update the scanner didn’t react and wasn’t recognized as usb device by the laptop.
The last time I connected the mini it suddenly was active and I did several test scans.
Is there any kind of crash log I can look into or send to you?
The problem didn’t show again so far, so I really can’t tell what the problem was.
The power output was stable all the time, so that’s not the problem.
I usually don’t use the wifi, but will try soon.
Really a great device you guys came up with, but I assume you know that:-)
If I run into the problem again, I’ll be back, but for the moment there’s nothing to do anymore.
Seems like a weird software issue, perhaps in combination with recent OS updates and stuff like this ( too many updates, interfering drivers, new security procedures by Apple…)
