Some computers may benefit from adjusting the keyboard polling interval setting. The default value is 01. On some computers, the card output may show evidence of corruption. Or, you may notice that the reader works on one machine, but, inexplicably, not on another. This may indicate that the problem machine is having trouble keeping up with the reader's output. You can try adjusting the keyboard polling interval setting. The image below shows the command to change the setting to 05. This has been found to be necessary for some machines. Values other than 01 or 05 have not shown to be more beneficial.
And here is the SREDKey USB Demo tool that you need to send the "53 14 01 05" command as mentioned in the instruction.
