Hi all,
I would like to ask if anyone has implemented a physical usb interface in a development board of altera that has not mounted a usb inf.
The core for usb1.1 and 2.0 are available but do i need certain physical layer to implement usb?
I heared that for low speed i dont need to implement anythin just drive the wires into the fpga but for high speed i need to implement the phy intf.
Any suggestions? Thanks
