Digital Cameras Photo Reviews of TRENDnet 2-Port USB KVM Switch Kit (Includes 2x KVM Cables) TK-207K (Blue)

Customer Review: Works well, except with VMware
Summary: 4 Stars

On the whole, I am pleasantly surprised that this inexpensive little switch works as well as it does. I was also pleasantly surprised to see that the switch will recognize Num Lock key-presses as well as Scroll Lock. (Scroll Lock can be problematic due to the horrible F Lock key arrangement on Microsoft keyboards.)

I am using it with a Microsoft wireless keyboard and mouse set, which has one USB connector and one PS2 connector (disconnected). It seems fully compatible with the mouse and keyboard. All the special keys and mouse buttons work just as when directly connected.

I am only using the keyboard and mouse portion of the switch since both computers have their own monitors, so I can't speak to display quality or performance.

The only major problem I've found is the one others have reported with VMware. When moving the mouse in and out of a VMware window where a VM is running, it can cause the switch to jump to the other computer. Worse, if VMware is set for the VM to capture new USB devices when in focus (I believe this is the default), it will try to connect to the KVM directly when you switch it back to the first computer. So, there is no way to regain keyboard and mouse control on the first computer without removing the switch and directly connecting the keyboard/mouse. I don't think this is a problem so much with this switch as with VMware itself, which apparently generates multiple Scroll Lock and/or Num Lock key-presses when switching focus to/from the VMs; so I'm guessing any KVM switch that uses these keystrokes would be affected.

You should also know that switching between computers effectively disconnects the USB keyboard and mouse device(s) from the first computer and connects them to the second one. This generates a cacophony of Windows kerplonk USB connect and disconnect sounds along with causing a couple of seconds of delay before the keyboard and mouse are connected to the new computer. Not a big problem, but something to keep in mind. Given the way this works, a simple mechanical USB A/B switch might work just as well or better for my needs.

My only other minor gripe is that I have to press Num Lock (or Scroll Lock) twice more slowly than is natural (about 1/2 second between presses). Any quicker and the switch does not seem recognize the keystrokes and doesn't switch between PCs.

The little instruction booklet that comes with the switch is put together in an interesting way. It seems to flow from back to front with no real rhyme or reason as to how the different languages are ordered. Whole pages of Russian, French, etc. are interspersed seemingly at random with English pages. I don't mind having the other languages in there, but the random layout must be a printing mistake which doesn't speak well to quality control.

None of these issues would prevent my from keeping this switch, except for VMware which I use frequently. I've not yet found an acceptable workaround for this, so I'm going to try the simpler IOGear switch that has a wired remote button and may not be sensitive to these keystrokes. The reviews of that switch have me questioning whether it will work with the wireless mouse and keyboard, but I'm going to give it a try.

Update: I received the IOGear GCS22U switch with the wired remote IOGear 2-Port USB KVM Switch with Cables and Remote GCS22U (Black) . It works just as well as this Trendnet for my needs, but avoids the issue with VMware altogether since it does not listen for Num Lock or Scroll Lock. I actually prefer the IOGear's small wired remote in any case.
