macOS 11.13 Big Sur does not show description() is n/a

[stephanschulz]

I used to be able to call ofIsStringInString(deviceDescriptor.description(), "Teensyduino") but since macOS 11.13 the descriptor is n/a.

I will have to dig deeper to figure out why

This is likely an upstream issue with https://github.com/wjwwood/serial. Perhaps get the latest version of that library and see if it works? If not, then it's probably some macos api change / call that needs to be updated.

thanks for the tip. I replaced the lib folder in ofxSerial/libs/serial but it did not fix the issue.

Hmm, perhaps leave an issue @ the wjwwood/serial repo. If you want to do some investigation, the relevant code in the original library is likely here https://github.com/wjwwood/serial/blob/main/src/impl/list_ports/list_ports_osx.cc#L239-L257 After a quick glance, the IOKit libraries associated with this don't seem to have any notable deprecations w/ big sur. I'm not able to test at the moment, as I don't have access to a machine running big sur.

Yes this branch solved the issue for me.
