DA1469x: Bus Resets on HID Generic InOut Port

[KWolfe81]

I'm experimenting with TinyUSB support on the DA1469x and am running on both the da1469x_dk_pro & on a custom PCB. My project is pretty much just the hid_generic_inout example. If I connect to the device within the first few seconds, I can establish a connection and everything his hunky-dory.

If, after enumeration, I don't attempt to communicate, I observe a USB Bus Reset signal along with a Suspend. The Suspend is expected, but not the Reset. In any case, I lose enumeration and cannot reconnect short of resetting the device.

Any tips on where to look or can I provide other information which might assist in getting to bottom of this?

Thanks!

It is probably be around the bus signal detection. I haven't tested much with this chip. Though suspended can be mistaken as disconnected event (they are similar in term of D+/D- state) and only different in VBUS (suspend still has vbus).
