The IOGEAR GCS42UW6 is a 2-Port Compact USB VGA KVM which allows users to share a VGA monitor, USB mouse, and USB keyboard between two computers. It supports multiple operating systems including Windows, Sun, and Mac. Users can switch between computers using a manual switch located on the top of the KVM unit. Being cabled based, users do not have to purchase additional cables in order to use the device. It is entirely plug-n-play and requires no software to run. It is also powered through the USB bus and thus does not require a separate independent power supply to run. It is the perfect KVM for those who want a well-priced, basic KVM that will allow them to multitask with two computers at their disposal.

Question: Will this work OK without a monitor connected (i.e. I just want to switch the kb/mouse over between my mac and PC - each has its own monitor.
Answer: The switches are designed to switch the video as well, but in theory it should work if you do not connect the video. Since it is designed to switch the video as well, we cannot guarantee that it would work in the way you are asking. A true USB only switch you could use would be

Question: What is the length of the cables?
Answer: Thank you for your Patience. Unfortunately, we are getting mixed answers, some say 4 feet, others say 6 feet and IOGear has not confirmed with us either way. If we receive additional information, we will be sure to update this page.

Question: Any agent in Malaysia?
Answer: Thank you for your inquiry. You can find a local IOGEAR distributor by contacting IOGEAR's Asia-Pacific sales department directly at:

Question: Can I use it to connect two computers to one printer
Answer: Thank you for your inquiry. This KVM is used for connecting a single user console (keyboard, mouse and video) to two computers. If the switch provides transparent USB, it may work to share a printer, but that is not a supported use of the device. Most likely, there is some form of keyboard and/or mouse emulation that may hinder its use as a printer sharing device.

For a KVM that supports printer sharing, you will want to look for a device that has USB hub functionality:

If you do not need full KVM functionality, you may be interested in a dedicated USB sharing device such as the IOGEAR GUB431:

Question: Will this device work with a wireless USB mouse? Or only corded USB?
Answer: Thank you for your inquiry. Wireless USB mouse support is pretty hit or miss with KVM switches due to the very different way in which wireless devices communicate. We are hesitant to say any KVM switch supports wireless devices unless the manufacturer specifically mentions wireless support. (even then there are often issues with spotty support for all wireless devices)

This particular switch does not explicitly state support for wireless devices, so we could not guarantee it would work. While it may function with a wireless device, for the best performance, we would recommend using simple, wired devices.
