Hi,

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.

Hi ritesh unde,

Thank you for your interest in NXP Semiconductor products and 
for the opportunity to serve you.
I was wondering if you can introduce the steps to replicate the issue.
I'm looking forward to your reply.

Have a great day,
TIC
