Hi,
I try to get to work my USB connection using the USB 1.1 Function IP Core and a Fairchild USB1T11A transciever. http://www.fairchildsemi.com/ds/US/USB1T11A.pdf I dont know where to connect the signal "rx_d" on the fairchild transciever chip. I read in the usb1_core.v "Just match up the signal names with the IOs of the transceiver". but what is the function of "rx_d" signal in usb1_core ? Does anybody have any experience with this chip ? thank You! |

Hi
I have tried same solution ( USB 1.1 core and USB1T11A). I connected rx_d pin to RCV pin on USB1T11A. I think it is right but USB core is not working. I you manage to run this please let me know. |

So
I managed to get it working. Problem was in module generic_dpram . I have chosen define VENDOR_ALTERA ( I use altera) - line around 100. After i selected `define VENDOR_FPGA , it started to work. I use USB1T11A transiever, rx_d pinnected to the RCV on the transmiter. |
