Hi,

I'm trying to run the custom HID example provided by ST for STM32L152c board. The device disconnecting and reconnecting multiple times after enumeration. I have attached a screenshot of the sniffer. Could anybody tell me why this is happening.

TIA.

Anyone?

On further analysis I have discovered that the device does not enter suspend mode when the bus is idle.
