One suggestion that needs to be rigorously tested is to blacklist the serial device of ExpEYES(VendorID:ProductID) for Modem Manager so that it will ignore it. https://askubuntu.com/questions/1231894/modemmanager-conflicts-with-arduino
That sounds very promising. Corresponding ModemManager documentation is https://www.freedesktop.org/software/ModemManager/api/latest/ref-overview-modem-filter.html So maybe the solution is shipping in eyes17 (or a better fitting package?) /lib/udev/rules.d/78-mm-blacklist-expeyes.rules with this content: ===== 8< ===== ACTION!="add|change|move", GOTO="mm_blacklist_expeyes_end" ATTRS{idVendor}=="04d8", ATTRS{idProduct}=="00df", ENV{ID_MM_DEVICE_IGNORE}="1" LABEL="mm_blacklist_expeyes_end" ===== >8 ===== (Repeat the middle line if you have multiple IDs) Needs to be tested by someone having an expeyes board ;-) As modemmanager already has several blacklists: /lib/udev/rules.d/77-mm-pcmcia-device-blacklist.rules /lib/udev/rules.d/77-mm-qdl-device-blacklist.rules /lib/udev/rules.d/77-mm-usb-device-blacklist.rules perhaps your device should rather be added there? Some blacklists also set the ID_MM_TTY_BLACKLIST variable instead of ID_MM_DEVICE_IGNORE Andreas
