for scanner PB61236 also known as Scan 600, also on the label is DC66J, which refers to the circuit board.
Operaing system - W98 & ME
Run the file before connecting the scanner to the USB port, the system will then find the driver.
Look in the scanner directory created and see all the .inf files
Worked well for me--- after I remembered to turn on the switch at the rear!!!
