Hello all


    I am a complete newbie to this DSP world and also for USB programming. I am using BF 527 EZ-KIT Lite.I have to develop a device driver with 3 endpoints configured respectively each for BULKIN,BULKOUT and ISOCHRONOUS IN  transfer. I was able to successfully execute the examples in the following path "C:\Program Files\Analog Devices\VisualDSP 5.0\Blackfin\Examples\ADSP-BF527 EZ-KIT Lite\Drivers\usb\bulk_redirect_io_app".

then i run hostapp.exe in this path "C:\Program Files\Analog Devices\VisualDSP 5.0\Blackfin\Examples\usb\host\windows\hostapp\hostapp.exe" through commandline.

What should i do inorder to start developing a driver with the above mentioned transfers and the end points configured? Could you please tell me from the scratch where i should start. I am going through the "USB OTG Controller" in the hardware reference manual and also read the USB spec 2.0 once.

I am pretty good in C Programming too. Please give me a push where i need to start.
