Hi, I finally got a chance to try this patch: "Determine maximum packet size via usb config descriptor". It works fine on: FT2232D, full speed FT2232H, high speed FT2232H, full speed (previously failed without the patch) I wrote a small program to help with the testing, which might be suitable as an example. Patch attached. -jim -- libftdi - see http://www.intra2net.com/en/developer/libftdi for details. To unsubscribe send a mail to [email protected]
