I thank everyone for their suggestions.
I had done every thing everyone said to try except for two and that at least gives me something to work with.
I had not tried using different USB ports. Since my Notebook has four I'll try that.(Thanks Sapphire)
And while I manually installed the USB port I did not check the Audio Devices in the System setting. I'll try that one also.
Since the PR54 and the KN2600 are very close to the same instrument that could very well be the problem. (Thanks Aprilla)
I doubt I'll get to test this before next weekend so if there are other suggection let me know and I'll be able to try them all at once.
Thanks All Again
