The HP.Switch.2500 script is coded to handle the initial splash screen with the 'Press any key to continue' prompt, so there may be something else going on.
If you can create a device capture for me I will look into the file to see if I can spot the problem. A device capture file records the communication between CatTools and the device you are having trouble with. You can create a device capture file as follows :
# Use the CatTools File menu to select the "Enable capture mode" option.
# Run the activity you are having trouble with. This should create a debug file in the \Debug folder.
# Zip up the resulting file and send this to me as an attachment.
# Remember to deselect the "enable capture mode" option again.
Please ensure that you *** out any sensitive information.
I noticed that all the usual header information we include in the debug files for your devices is missing. Are you running an older version of CatTools? If so, then it is likely your HP device script does not have the fix which was implemented to handle the 'Press any key to continue' prompt.
If you haven't already, try upgrading to the latest release and see if this resolves the issue.
