Many manufacturers of "scanners" have not released any device-drivers for the scanners for Microsoft Vista/7/8 -- they stopped with the Windows XP software. Check the manufacturer's web-site, to look for any declaration of "support" (or "unsupported") or any updated device-drivers for your specific model.
Hi, First install software driver if finish, connect your scanner USB cable to USB ports of CPU(make sure that your USB ports working good, test also using your USB flash drive).then you can see on screen automatic detect your scanner. if not detected try to change your USB scanner data cable. then try again connect to USB ports of CPU.
Just let me know if not yet working. Thanks for using Fixya.
