Force COM Port for USB Serial Device
The Honeywell Scanning & Mobility (HSM) USB Serial Driver is a CDC ACM driver that exposes HSM
USB scanners as a virtual COM port to the operating system and applications.
If you chose a specific port number for USB Serial (Virtual COM) during ReM client installation (see
page 2-6), you must ensure the driver always assigns the same port by using the Force COM option in
the HSM USB Serial Driver:
1. Connect the USB serial scanner to the host.
2. Open the host Device Manager (Start>Control Panel>System>Hardware>Device Manager).
3. Expand Ports (COM & LPT) and Universal Serial Bus controllers. If the USB serial device is
installed correctly, the scanner should display under both categories:
Note: Honeywell scanner models that begin with MS or IS (or legacy Metrologic devices) display as
“Honeywell Bidirectional Device”. For other Honeywell (and legacy Hand Held Products) devices,
the scanner model number displays.
4. Under Universal Serial Bus Controllers, right click on the device.
5. Select the Details tab and make a note of the four digits following “PID_”. In the example below, the
four digits are “0730”.
6. Click OK to return to the Device Manager.
