Hi,
I have went through the AM335x_USB_Driver's_Guide and configured it as mentioned there. When I connect my device to the PC I cannot see any USB serial device in the device manager. When I use the command lsusb , I get the response as
Bus 001 Device 001: ID 1d6b:0002 , but I cannot see the serial device in device manager.
Here is the log :
