Hi

Is it normal for a program that are using usb serial to stop running If the usb is not plugged in or should the program continue to run

Hello,

The USB Init routine will by default wait forever for a USB enumeration, that is the PC request for info and the device is setup correctly with device drivers.

If you go into the USB component properties then you can enable a timeout which will allow the init function to wait for a bit and then resume your program. The return value from the init routine then tells you if the USB is active or not.

Hi Benj

Thanks for the info. I got this one sorted just before you replied.
