Serial cable is known under ttyACM0/1

Former Member
Former Member over 13 years ago

Hi

When I connect ZED Board to the computer,
its serial link will be recognized as
/dev/ttyACM0 or /dev/ttyACM1 device.

However for ZC702, it is knows as /dev/ttyUSB0

I want to know the source of this difference?

Why for the ZED Board we don't simply have /dev/ttyUSB0 again?

Because /dev/ttyACM0 has a lot of problems. For example, when I turn of the board I should exit Minicom.
And then next time that I turn on the board it appears as ttyACM1 not 0 and i should reconfigure every thing again

do you know any solution to this?
thanks

    BTW I recently switched from minicom to picocom, which is much handier for this kind of application. No config saving necessary as you give all the required parameters on the commandline (e.g. picocom -b 115200 /dev/ttyUSB0)
