In the readme file of the example USB cdc Virtual com port (usb_device_cdc_vcom) it is written :
@Because there is no dynamic detection between the host and the device, the COM port must be closed from
the terminal tool prior to unplugging the CDC device. Otherwise, the CDC device won’t get recognized next
time when plugging in with the COM port still opened.
Is this behavior a constraint of any virtual com port OR is it specific to the hardware frdmK64 OR is it specific to this example (and can be improved) ?
I do not find any information on this point and I have no CDC devices on hand to compare.
Thank you in advance
