The Microtek USB scanners cannot work with the ALI Aladdin V chipset. Microtek is aware of this problem, they have posted Ver1.4 usb drivers for some scanners that fix this problem. My microphone doesn't work. Double click on the speaker and you see volume control sliders. Choose options then properties.
Check mark the microphone then click ok.
The volume control sliders now include the microphone. On that slider is a MUTE that is usually checked- uncheck it. You now have it working. I have formatted my hard drive and have a cd-rom attached to a sound card. I'm trying to install from the cd-rom, but the drivers do not see it.
