Summary: Trendnet TK-409K 4-Port USB KVM Switch Kit with Audio, Includes 4x KVM Cables (Blue) USB stops working after a while. Tried using 2 laptops and in both cases get a Windows message saying it cannot recognize the USB attachment.
Summary: My purchase with the TREADnet kvm switch is great! Very sleek and portable, requires no outlet for power. Great addition/replacement to my office at work. I have a 6 year old KVM switch and OMG that thing was huge!. I am glad I purchased the TREADnet KVM Switch, and if mine were to break down in the future or gets destroyed by unforeseen circumstances, I will buy another one. HTH!
