windows usb device disconnect reconnect

I am using a Kinetis Freedom K22F evaluation board. I have a program running that enables a USB CDC VCOM device.


Windows sees the device just fine and communication is not a problem.


The problem I am having is each time I restart the debug session (I am using Segger J-Trace), I have to physically unplug and replug the USB CDC VCOM cable so I can talk to the device again.


I am using either PuTTY and RealTerm to communicate with the device.


Is there some 'reset' register or reset sequence available with the K22F eval board that one can use to 'simulate' the disconnect and reconnection of the USB device?
