Hello,
We have recently ported our driver/api towards native 64 bit but it is very early material, barely beta. Note that we don't expect problem, lack of soak testing.
I assume you might be interested to use the given components, the actual dlls, libs and headers as well as the device driver running natively on 64 bit. The chery on the cake being DMA using the whole computer memor space; implictly no bounce buffering done by the OS.
I can prepare an archive with this components if you wish, just let me know!
Best Regards,
Arnaud
