Hi,

I was wondering if anyone has successfully implemented and used the USB 1.1 core. I'm trying to simulate it in Quartus, but I seem to be having trouble in the usb1_idma and usb1_pa modules. The data (device descriptor) is not read correctly from the IN FIFO by the idma into the fast prefetch FIFO. I was wondering if anyone else has had this problem.

I would also like to know which FPGA, memory settings(in generic_dpram.v) have been successfully used in usb 1.1 projects. Has anyone used Altera FPGA's? I'm using the FLEX 10KE.

Thanks in advance

Rahul
