Multiple USB scanners with the same Manufacturer device ID
Posted on 2007-04-05
I have connected 6 Fujitsu fi-5110c scanners to a Windows 2003 server, using a USB hub. All the drivers are installed correctly and each device functions fine. The problem I have is that when I disconnect the devices and then re-connect in a different order to the original process, the scanners are being assigned incorrectly by Windows. (I.e. scanner 5 is connected first, and Windows recognizes this as being scanner 1). So I need to connect them in the same order I originally did.
Another problem seems to be the event handling when the scan button is pressed (i.e events are triggering the wrong device).
Is there a device ID in the registry that could be causing this? I notice the device IDs are the same for each one, event though the control set 001 .. 007 is OK.
