Hi,

How can I check for USB barcode scanners that are attached to a PC? Not sure if the make and model can be detected as well?

Hi Samuel.

Not sure if this will help. I used this script to report local printers attached to pcs:

selects “PortName from win32_printer” of wmi

I did some more research on where this might be found and it’s only available in the registry. However, as it’s value is different across every pc, how do I scan through a particular tree location for this value?

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB**“LocationInformation”=“Symbol Bar Code Scanner”

Any help would be greatly appreciated…

Thks,

Samuel

Does this work?

exists values “LocationInformation” whose (it as string = “Symbol Bar Code Scanner”) of keys of keys of key “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB” of registry

Note that this will iterate over a good amount of registry keys so it might be a good idea to raise the evaluation cycle to something like every 12 hours if you put this into a property… although it seems to go pretty fast on my computer…

It works, but it also returns values if those devices are no longer connected. How can I do it such that it only reports if the device is currently connected??? It seems to run pretty fast even over a older machine so I guess performance is not so bad.

I am not sure about the currently connected question… Do you see any registry keys that indicate that the device is currently connected?
