USB response getting slow after a long run

Question asked by Anantha Raman on Dec 28, 2016

I am using STMF427 mcu. We have used the USB CDC library to have usb logging enabled. The issue I am facing is really weird. I have a console based application to set all the required serial number, model number etc. When my testers are doing the settings through a script for 100 times after some number of loops I see that command response becomes very slow.


For eg: 

I enter the command get_serial_num I wont get the response now but when I give the next command get_model_num I get the response for the previous command.
