Umax Usc 5800 Scanner Driver For Windows 7 64 Bit

VueScan includes its own built-in drivers for legacy scanners.

You may need to disable Driver Signature Enforcement temporarily if the above fails (see Method 3 below).

No hunting for unsigned drivers, supports RAW scanning, better color correction. Cons: The paid version costs around $40-$90, but the free trial lets you test if your scanner works.
