Windows XP and Windows 7 is proven to work fine with USBCNC. Windows Vista is not.  


USBCNC requires soft-real-time behavior of your PC. Sometimes a bad driver of your video-card, sound etc may be the cause of problems with USBCNC.  
USBCNC requires a USB communication speed of about 150 times/second to and from the USBCNC CPU.

There are PC’s with bad USB chipset on which cannot handle this.  One of such PC’s is the ACER notebook time-line series. From the better brand notebooks like Dell, HP, Sony, Toshiba  I have not yet heard problems. When you encounter this, you may be able to solve it by adding a PCI USB card.
