I had to copy data from the USB stick installation CD to install on a CD player-free notebook. No problem either.
Finally, what I wanted was to scan directly from the scanner to a memory card, without the need of the computer. (Document storage). Royal, 2 keys to type and is in pdf on the memory card. (Just one question at the end of scan for an eventual next page ..)
In short, all positive for now.
2 months after the purchase, always packed. No complaints.
