Add USB hub support

Narendra,

I tried googling “USB hub ti-rtos” and there were several E2E forum posts that popped up that might be useful to you.  In particular:

Scott,

Sorry for the late reply.

in first link  the reply is only for CDC drivers and does not talk about Hub driver.

in  the other link ,  the guy has already implemented the hub driver and is asking for help in implementing MSC driver.

I am pretty new to USB.  We are connecting USB2514B hub controller from microchip.  I modified the "usb_host_hub" project for the customized board(not USB part, but display part) and tried test reading from a pen drive. its goes into  infinite loop inside "usbhostenum.c" trying to enumerate the device.  

1.  I don't see any interrupts being generated

2. How do we know what it is trying to enumerate the hub controller  or the pen drive

I am attaching the project. Can you please tell me where I am be going wrong

Thanks in Advance

Narendra,

OK, thanks for the additional info, and for posting your project.

From what I can tell, this project you posted is a StarterWare example.  There is a StarterWare forum that you can post this to get some help to get this working on your board: https://e2e.ti.com/support/embedded/starterware/f/790

Scott,
Thanks for the reply. I will post the same on starterware forum. Finally I need to support the hub on TI-RTOS. So I may come back to you for help when I port this code to TI-RTOS.
