I can't get a BCD325P2 to communicate with the computer. I followed the Wiki instructions on installing the driver, and Windows responded that the driver is already installed. Yet, I can't get either FreeScan or ProScan to communicate with the scanner. The autodetect tells me Port 3, but when I try to upload the program to the scanner, it says that there is no communication with the scanner. Yes, the scanner is turned on. What am I doing wrong?
