Hello,

I am sorry for delay in response. Here are comments from our side.

(1) According to me, you should not make any change in development board. Because in this case, I do not think it would help. See attached image - De1_Soc_USB.png.

(2) For Device mode, ID pin status should be 1 ( HIGH ). You can connect it to VDD or you can keep it left floated. ID pin has internal weak pull up resistor.Refer USB3300 datasheet. So if you will not connect it, it will automatically detected as high.

(3) Sorry I do not have idea about that.

Let us know if you have any doubt.

Cheers,

Bhaumik
