$ sudo cu -l /dev/ttyUSB1 -s 115200I get a connected message but no further progress is done. When i press Power button briefly, no activity is shown. I have tried with two phones but no success on any. I have checked the connectivity between headphone jack and USB serial chip via voltmeter, it is fine as well. Also tried by doing Master reset on phone but no use. What can be issue and how can i fix it. ?Kindly ignore any mistakes, i am new to this domain, couldn't find much help on google as well :(
