USB Enumerate and Disconnect loop

Question asked by Matthew Smith on Mar 6, 2018

I have inherited a project which uses the USB interface on a Kinetis (MK22FN1M0VLH12) to pass sensor data to a host PC or thin client.  The problem I am having is that the device enumerates and appears in the device manager on a Windows PC, but then after a short time disconnects and then re-enumerates.  This repeats in an infinite loop.  I'm looking for some guidance as to where I should be looking in the configuration that could cause such an issue.  kinetis mk22 usb design
