Dear Experts
Have you ever tried usb_dev_serial on both TM4C123G LaunchPad and LM4F120XL LaunchPad?
It is strange that this driver works on LM4F120XL but failed on TM4C123G.
I tested 2 TM4C123G LaunchPad but all failed so I don’t think this is a h/w issue.
Please help to give me some comments.
Thanks.
