Lost isoc frames in XP
Hello! We have a program receiving realtime data from device and using CyUSB driver. It works perferct in Win Vista and 7. But in XP sometimes (especially on weak computers or when processor is loaded) isochronous packets are lost (holes in signal appear).
Developer of device firmware tells that driver is blame. Computer must send requests for usoc packets 1000 times per second, but it doesn't. If this is true, I suppose that someone has already met with this problem. Can anyone help to overcome it? Thank you.
