All I can find is usbsoft.exe in reference to a scanner - the key value you list above is merely the description in the registry of the find you did on usbsoft.exe. HP states, "Some PCs might be shipped with their USB I/O ports disabled in the PC'sBIOS. If the HP ScanJet installation program detects that this is the case, it inserts a utility into your PC's AUTOEXEC.BAT file to turn on the USB I/O ports each time your PC is restarted.
In some cases this might not succeed in enabling the USBI/O ports. If this is the case, you might need to enable them manually. If your PC is unable to communicate with your scanner after you have followed the installation instructions exactly, refer to the installation troubleshooting section above. If this does not resolve the problem, you should contact your PC system vendor for instructions on how to determine whether the USB I/O ports are enabled and how to enable them.
If you do manually enable your PC's USB I/O ports after the HP ScanJet installation, the utility that was inserted in the AUTOEXEC.BAT is no longer needed and can be removed. Be sure to make a copy of the AUTOEXEC.BAT file before you make any changes. Using a text editor such as Notepad, open the AUTOEXEC.BAT file, which is in the C:\ folder on your PC. Find a line in the file that starts with the following text and remove it.
C:\USBSOFT.EXE
Now restart your PC. If your scanner fails to operate after your PC is restarted, you will need to restore your backed-up copy of AUTOEXEC.BAT and restart your PC again."
