The computer does recognize that "some" USB device has been attached, but can't figure out what it is. Was attempting to replace a Tripp-lite with this one because I thought it was giving me problems. I called tech support and they had no ideas about how to remedy the problem. This adapter would work on USB ports right on the laptop, but not on the docking station. The whole point is to connect this up to a KVM switch - so it must work on my docking station. This is the only USB device to do this to me (works on built-in USB port, but not docking station port). Problems turned out to be the attached Keyboard and Mouse getting flaky - so the old adapter is back in place.
This is one of the few USB to PS/2 adapter that works with Cybex / Avocent KVM switch without skipping, multiple entries or lack of power draw from the Keyboard PS/2 input. The cables was thinner than the older version of the same model from IOgear but I have not seen any degradation of performance.
When I press a key once, I often get multiple copies of the key when I use this adapter. I don't have that problem when I use the same keyboard on a different computer without this adapter. The errors are so frequent that I stopped using this.I only used one of these, so I can't tell whether the design is bad or I simply got a defective unit.
Just filling in field information here, this product did work to connect an old Omnikey keyboard to a Dell Optiplex 755. No problems so far as I can tell.Edit: And, it worked to connect the same Omnikey plus a Logitech Trackman Marble+ (both of which I intend to take to my grave) to a new Dell Inspiron laptop. Two for two.
I tried a couple of PS/2 to USB converters, and always had issue until I put this cable in place. IOGEAR said it was the only one they tested with, (Go figure) but I am happy with the results. Not to mention it cost me less then the other cables did.
