about USB of DE1 Soc board ,,,

Hello,

As Galfonz told, Soc can operate in either OTG, host or device mode. But in DE1-SoC board, it is hard wired in host mode. Due to this, you may (or can) not be able to use that functionality.

One option here is to use USB 2.0 Device IP core ( which will be implemented in programmable logic) along with ULPI add-on board. As there are GPIO headers on that board, you can use ULPI add-on board. In this way, you should be able to send streaming data to Host PC via USB. I am sharing links related to USB Device IP core and ULPI add on board :

See whether this is useful to you or not.
