I am using Leap 15.2 with AMD Athlon CPU. The system is not recognizing attached USB devices. The problem appeared from nowhere as it was working 3 days ago. Further, altho the is a /dev/ttyUSB0 device, assigning the Arduino to that port does not work and I question if /dev/ttyUSB0 is actually functional.
The devices are a Arduino and a Digilent Nexys FPGA board. Needless to say I cannot program ether device and my development efforts are at a standstill until the problem is solved.
I would like to fix it so the attached USB devices are recognized at boot time, but in lieu of that solution, how does one mount these generic devices?
3 days ago I had /dev/ttyUSB0 /dev/ttyUSB1 /dev/ttyUSB2
