Title: Worst USB Device Ever.
Review: I am very disappotinted with the UMAX 3400. This is the only USB device I have owned that is not compatible with my PC. After 5+ hours including over an hour on their toll tech assist line, I have given up and will return this scanner. It is not plug and play. Technical assistance was poor - they told me to disconnect all USB devices, mannually edit the windows register, . . . . Even after being emailed detailed instructions for "difficult installations" and trying the laborious procedure 3 times, my scanner still causes my PC to crash. I have numerous other devices that work fine with no conflicts inluding a USB hard drive, USB CD reader-writter, USB MP3 loader.
