I'm a complete newbie to USB, wondering if someone can give me some advice about the easiest way to verify that the usb connectivity for my custom 526 board is working correctly? I figure that if I can just verify that the PC recognizes a connection, and my 526 is enumerated as a device, I should be okay. All I want to do at this point is verify that it will work.
I thought it might be a good idea to take an example from the 526 ez-kit which accomplishes this, and port it to my hardware. To that end, I took the usb audio app example, changed the settings to match my external memory, and tried to run it, but when I plug in a USB cable I get a message from my PC that says "USB device not recognized" and a message from visual dsp saying "USB communications error - failed to halt target".
Now, one difference between my hardware and the ez-kit is that I have a standard 'B' input on my board, versus a mini-'A' input on the ez-kit. But, this is a peripheral application, so this should work, shouldn't it? The USB_OTG_DEV_CTL register setting at this point seems to indicate that it is expecting a 'B' type connection...
