Access the USB in Microzed Board

gauravagarwal.27394@gmail.com over 8 years ago

Hello,

I'm using Microzed evaluation kit for my development of interface card. Burnt Pulsar Linux OS given as per instruction.

Problem: I'm not able to get the device address of USB (which is just below the Ethernet) .

Doing ls /dev/ttyUSB* or ACM* is not helping me much.

do I have to install any thing?
