Hi Sir,

Can we work the USB2 device without using V-bus concept in RM48L952 controller.

If so, please tell us any software modifications to be done on the driver code of USB device. 

Please, help us to solve this issue as early as possible.

Best Regards,

    Hello,

    The USB host controller is the bus master, so it initiates all data transfers and polls the devices. The USB host controller is constantly communicating with devices, sending them request. If a device does not respond to any requests for a while, and its data lines are both low, it is considered to be disconnected.

    Please check the one data line is pulled HIGH.
