I have followed the installation guide in Installing PixyMon on Linux. My OS is Mint as it suggested.
The PixyMon is able to detect the Pixy, but it cannot connect.
I have tried the camera in Win10 and Arduino, it is working perfectly. I am sure it is not a camera problem.
I have also updated the firmware to the latest.
For your information, my version of the OS is:
Distributor ID: LinuxMint
Description: Linux Mint 19.1 Tessa
Please help me to get it working with Linux, because we are going to use it in the Linux ARM.
