USB Corrupt CRC in packet

I have a situation where the registers appear to be set up correctly, but when I put data into a transmit FIFO, the output on the USB wires is a single byte with a checksum of 0x0000.

Put many bytes into the FIFO
  a - One byte comes out
  b - The wrong byte comes out
  c - The packet has a checksum of 0x0000 and is rejected by the host.

Does anybody have any experiance with this error, or any idea what can cause it?

Thanks
