Hello,
I am interfacing a DSP to the Philips USB D12. I am a little fuzzy on exactly what happens during enumeration.
I have the PC will recognize the D12 as soon as I active the pull up resistor, but then I have no idea what to do.
I assume it will be wanting a device descriptor, and that it will be wanting it at endpoint 0, but when do you send it? Is the host not supposed to ask first?
The spec sheet on this part is little to no help on the process of enumeration. It allows certian commands that sometimes work.
Has anyone had any success with this part? Exactly what order did you go through to get it to enumerate properly?
Thanks for any help,
Rob
