Summary: Purchased one, hooked it up per manuf directions. No signal on the monitor. Returned it thinking it was DOA and got a replacement. Same experience. Running Windows XP SP2 (Home version) on both computers (HP and Compaq). I WILL BE PURCHASING A DIFFERENT BRAND TOMORROW.
Summary: Trendnet TK208K 2-Port PS/2 Audio KVM Switch Returned the first switch because the switch would not function. Amazon was fantastic and sent a replacement overnight at "No Charge". I have been trying to get the second switch to work for a couple of weeks. TRENDnet help (a technician in a foriegn country working from a script) finally has asked me to idenitfy the motherboards of both computers.
Summary: The KVM doesn't work with my new HP DC7100 PC. The keyboard and mouse is not recognized by the BIOS (I can't press F10 to get into the BIOS setup, for instance). I swapped cables/ports/etc. and it is KVM speaking to the HP PC. The KVM works fine with my 8 year old PC. I reflashed the HP PC's BIOS with the latest, no change. You can't reflash firmware on this KVM. Repeated emails to Trendnet customer support were unanswered, so I called their support folks.
Summary: I tried this piece of junk to hook up my Windows 98 computer and my Windows XP computer to the same monitor, keyboard and mouse. I could never get a signal on the monitor. Then I bought a similar device from D-Link (item # KVM-121 - 2-Port KVM Switch with Audio) which was cheaper and worked like a charm. Don't waste your money on Trendnet, get the D-link device. You will be much happier.
Summary: I followed the directions and hooked it up in the correct order, MULTIPLE times, never could get it to see the keyboard or mouse and never would pass signal to the monitor. I tried hooking up to different computer and still the same problem.
Summary: This product is exactly what I was looking for. I have been using it effortlessly for approximately a month now. I have not had any problems with it at all. I would highly recommend this product.
Summary: I just received and connected mine up today, and it's pretty much perfect. It's small/compact, includes all cables, and features audio (as well as video, obviously) switching. What more can you ask for in a $27 KVM switch? I've never bought anything by Trendnet before, but the TK-208K gets my highest marks.
