Hi

I am a developer looking at Cy7c68013 as a replacement for cy7c68001.

When using the Cy7C68001 Device, "BUSACTIVITY interrupt : detected either an absence or resumption of activity on the USB bus." was used to determine the USB disconnection.

Is there a way to detect absence activity on the USB bus on Cy7C68013A?

Hi,

>> In case the device is self powered, kindly refer to the KBA: https://community.cypress.com/t5/Knowledge-Base-Articles/USB-disconnect-reconnect/ta-p/258067 

>> You could also try to set a flag in TD_SUSPEND() and check since this function is called when host is disconnected.
