I am using OM13092 LPCXpresso with LPC54608. While using MCUxpresso with USB example usb_device_cdc_vcom, it was working fine with echo back of byte I was transmitting on port.but suddenly it stopped working. I can view VCOM port in device driver but it doesn't echo back any data.


I tried with following options :

1. Reinstalling vcom port driver

2. Reinstalling MCUXpresso IDE v10.0.0

3. Swapping USB ports on PC


I am using Windows 7 professional, 32 bit OS.
