I have a Motorola LS2208 scanner with a USB interface. I have the scanner installed and have version 1.8.5 of the Symbol COM Port Emulation Driver installed and the device does what its supposed to do. I scan barcodes direct into hyper terminal. The problem I have is that when I reboot the PC the device doesn't work until I unplug the scanner and reconnect it again. Before I reboot and when the scanner is working in device manager under HID I have Symbol USB Com Port Emulation and Communication Virtual Port Com4. When I reboot I stll see the Com POrt Emulation device but loose the Communication Virtual Port and have instead an unknown device. The properties for the unknown device say the device is working correctly but hyperterminal doesn't see the port. When I unplug and reconnect it works straight away.
After doing some googling I have found release notes for a version 1.8.6 of the emulation driver which states that 1.8.6 includes Windows 7 support but I can't find a download link for 1.8.6 anywhere. I therefore am assuming 1.8.5 isn't 100% happy running on Win7.
I know the 1.8.5 driver does work on Windows 7 because I have a second PC with it working. I have tried everything including swapping scanners and even doing a clean Windows install but am having no luck with it.
