USB Interfaces User’s Guide
However, you may want to turn off and on serial number reporting just for particular product IDs. If you wish to do this, use the
following directions for changing your computer registry.
Only change your computer registry if you know exactly what you are doing. If you delete or change
important entries, your computer may stop working properly, resulting in loss of data.
In Windows 2000 and XP
1
, you can ignore the serial number for a certain device. The registry key is:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\UsbFlags]
To ignore the serial number of a device, create an entry under the above …\UsbFlags key. The name must start with
“IgnoreHWSerNum” followed by the vendor and product ID of the device. The value for the entry is 1 for disable. For example:
IgnoreHWSerNum0536016A= 1
The Hand Held Products vendor ID (VID) is 0536 (hex). The product ID (PID) depends on the interface you choose. See
VID
and PID Table
below for the PID of a given device. You can also use the MS tool, UsbView.exe, to find this information.
The entry below appears after a fresh installation, and enables the serial numbers globally.
We recommend leaving this setting
unchanged.
GlobalDisableSerNumGen = 1
Details for COM Port Emulation
If you have Administrator rights, you can create a text file that ignores serial numbers for the COM port emulation interface of
Adaptus Imaging Technology device(s). Below is text that can be copied and saved as a file with a .reg extension (for example,
IgnoreSerialNumbersForComPortEmulation.reg). This
must
be saved as a plain text (ASCII) file. Double click on the .reg file to
add this information to the registry.
