I know someone of you have helped me in my replies regarding USB Implementation before. I downloaded the USB Core (referred to as the Japanese version). The beauty of this core is that no hardware is required. Just need to connect the D+ and D- of the USB cable to pins of the FPGA.
The facts.. I changed the code around so that it has a altera pll running and producing a 48Mhz clock for the usb. I connected some of the output pins to the leds to see what's going on. I uploaded the program and connected the usb cable to the pins and to the PC (and added some circuitry like 3 extra resistors). and Behold, the program on the FPGA actually does something. I know it's working because when i connect/disconnect the usb calbe, the lights on fpga change their pattern for a small amount of time..
However I can't test the actual communication. The reason being, when I connect the usb cable to the PC, the PC recognizes a new USB device is attached (as win2k shows in the system try all the usb devices.), however is unrcognised as VALID drivers are not installed.
What I need is some help/tips on how i can install a driver for this product. The fpga has been configured so that it recognises a vendor ID of C91 and product ID of 2001. I have tried playing around with .inf files, but win2k rejects all of them and uses the standard c:\winnt\inf\usb.inf file.
I'm so close to getting this thing to work.
Pls help/advice Regards
