Try installing the Ubuntu package libusb-0.1-4 if it is not already installed.
It's already nstalled, any anathour idea ?
You can try using a different USB port.
There used to be an issue with certain scanning software where the scanner would be sent a "sleep" signal after a scan, so then it had to be restarted or unplugged/plugged in again to work for the second scan. I'm not aware of any Samsung scanners that were affected and it was supposedly fixed years ago, but you could try a different program to do your scans and see if that makes a difference.
Otherwise, not really. It may be an issue with the USB software rather than the Samsung driver, but historically bugs that have been filed citing issues with closed-source software like this driver have been closed without resolution.
