Trying to run a Pop3 and Mini2 camera via USB-C cable to a Mac Studio (M2 Ultra running up-to-date Sequoia and current Revoscan5 build). When connected Revoscan5 fails to see the cameras. The Mac sees the devices on the USB Hub and recognizes them correctly. When running the app via Terminal with verbose logging and monitoring in Console I get the following errors: Error from Terminal: _probeMain–ossconnectwithtimeout–failed! 127.0.0.1-14075_ Error from Console: _appleusbhostuserclient::opengated: failed to open usb3 gen2 hub@06500000: provider is already opened for exclusive access by AppleUSB30Hub_ This error persists across users, different cables (including original), using external hubs (with and without power), software reinstalls. This does work on an M1 Max studio (Tahoe) and a Macbook Air (M2, 2022). I have limited Macs at my disposal for testing, but this seems specific to the M2 Ultra chipset. From what I am reading about the M2 Ultra chipset is that it controls the USB roots more strictly. The failure to bind is telling me that Revopoint’s software isn’t allowed through the AppleUSB exclusivity. If this is a kernel level driver conflict or some design-level limitation between the Revoscan5 platform and the architecture, I don’t know enough to determine. Throwing this out for anyone else experiencing the problem or has any thoughts. Thank you for your time. ---

Hi, thanks for your answer. I tried this before, made restart, different USB connection, deleted preferences etc but nothing helped. It worked again after deleting and reinstalling Revoscan. Hope next time it will still work. Not the best option everytime to delete and reinstall. One thing also kept my attention: I always have to force quit Revoscan because it doesn´t shut proper on it´s own… Yes, I might contact them if next time same thing happens.🤞
