This is an electronics question. :-)
I have problems scanning documents.
To get a scan to work, I have to unplug the usb cable (that goes from desktop to scanner)
Then reopen my scanner app and then it scans.
I could not find something that would let me stop/start the connection between the cable and scanner without actually unplugging it.
I cut open an unused USB cable and found a black,green,red, and white wire and some uninsulated wire. (Maybe shielding)
Thanks for any helpful suggestions.
