Compiler/TM4C1294KCPDT: USB CDC To run on high speed. [2.0]

Part Number: TM4C1294KCPDT

Tool/software: TI C/C++ Compiler

Hi All,

TM4C1294KCPDT - Serial - CDC example.

I have create an application that runs on top of USB CDC layer. (i.e. application that uses CDC layer as a channel).

This is working fine.

I wish to change the USB speed to 2.0 from existing 1.1.

In order to achieve this the following change is made,

In usbdcdc.c, structure g_pui8CDCSerDeviceDescriptor is modified with the 3rd parameter, i.e from USBShort(0x110) to USBShort(0x0200). and usblib project is rebuild and then the application project usbserialdevice_EK_TM4C1294XL_TI is rebuild. And then the application is executed.

Is the above procedure correct? Or is there any other settings to be done from the application?

Thanks,

Jay
