USB Disconnect, Reconnect Issue.

While I was getting my USB CDC VCP working using CubeMX, and thanks to everyone who gave feedback, I ran across a statement regarding a bug in the USB stack. The issue was with the handling of a disconnect / reconnect event and device manager not recognizing the port anymore.

Up until now, I have seen no evidence of this. I've tested a variate of scenarios, everything from a cold start of the target to a hardware reset , to disconnecting then reconnecting the cable, to restarting the PC while the target is still running. All of these scenarios resulted in a proper connection. I'm just trying to see if there is some oddball corner case that I have not anticipated. Has anyone run across something like this, and if so, how did you address it?

Regards,

Mark
