SerialPort.getCommPorts() doesn't return list array in Linux(Linux Mint 17.1) #16

The expected behavior would be a list returning at least one port (checked using another program), however, it returns empty. No stack trace, no errors, just an empty list.

Thanks for the issue report. Could you give me a little more detail about the device you are trying to connect to. It is a USB device or an actual serial port? What is the native device descriptor it is using (on Linux, should be something like "/dev/tty****")? Are the other programs you are using able to actually open/read/write to the port, or just enumerate it? Thanks.

It is an arduino mega 2560 connected through USB serial port. In Linux it appears as /dev/ttyACM0 and yes, I can confirm it being existent as I am able to open, read and write from processing and from the arduino IDE. Thanks for the quick response, hope we get to a solution soon.

Sorry for the very delayed response. Please try the following library version and comment back whether or not your device is now enumerating properly. Thanks!

Thanks for the support hedgecrw, the library now enumerates correctly. Great library with excellent support!

Having the same issue. Where could I find any previous version, such as jSerialComm-1.3.8.jar? Thank you
