USB - HDMI-CEC Adapter

I purchased this device to use with a Linux computer running Kodi. After solving a permissions issue (the kodi user must be a member of the dialout group) this device is working flawlessly! With my older Samsung TV (LN46A550) it even shows up as a separate entry in the source menu and whether the user chooses the PC (existing HDMI entry for my computer) or new Kodi entry, this device auto switches to itself. Kodi mapped all the buttons on my existing TV remote in an intelligent way, including mapping CH+ and CH- to navigate up and down a full page within the Kodi menu system. The remote's info button does not function with Kodi (the TV has it monopolized I suspect) but in place of that the return button functions to bring up the contextual menu, and the exit button acts to back out of menus one at a time. I could not be happier with this simple, easy to use device, and I think my wife and mother in law will also find it a treat to use. I had an RF keyboard for years and more recently one of the little air mouse remotes, but I will be putting those devices away for good and enjoying the simplicity of using the TV remote for all Kodi functions.

This device is buggy on OS X. Pulse Eight claims OS X support, but does not provide a way to flash the firmware if you are on OS X and the device behaves erratically. If the device is plugged in when OS X boots it is not detected by libcec-based applications (such as Kodi). You have to unplug the device's USB cable and plug it back in after the OS has booted. You can find some code on the Internet to force a software reset on the USB port which will redetect the device, but that's kludgy.Outside of those issues, the device performs adequately. A 1-star review may sound harsh but consider the following:1) The manufacturer clearly states OS X support, is aware of the issue above, and is ignoring it.2) The primary use of devices such as these are for HTPC setups. The last thing I want to have to do with my HTPC is have to friggin' unplug and replug a USB cable every time I turn it on.If you aren't using OS X, this device is probably what you want.

Works perfectly! Moved from Raspberry Pi LibreElec to Intel and lost the native CEC functionality provided by the Raspberry Pi. Plugged this in, and remote functioned exactly like before (with Raspberry Pi). Highly recommend this solution for anyone else in a similar situation!

For CEC this works great no issues. There is an open source library that you can use to created your own CEC control apps. There are also 3rd party apps that allow you sleep and wake your TV like a monitor or switch off your AV receiver; which is probably why you’re looking for this product anyway. If you have problems sleeping your PC its probably a software issue. Look for another 3rd party app or change your USB sleep settings.As noted by the manufacturer this product will not work at 18Gbps. This means high bandwidth modes such as 4K 4:4:4 @ 60Hz does not work. Since it is a passive coupler it will pass the signal but it degrades the signal too much to work reliably. It really should be updated to work with current HDMI standards since $5 couplers work without issue.If you need full HDMI 2.0b functionality you’ll need to buy a splitter to split your video card output between the TV or other AV equipment and this adapter. Make sure the TV side of this adapter is plugged into the one of the splitter outputs. Some splitters will not split the signal if it does not detect a valid HDMI device. In that case you’ll need an additional cable to run to your TV or better yet use a HDMI dummy plug to spoof EDID. If you want the technical details: CEC works over a shared 1-wire bus. That means as long as your splitter supports CEC passthrough it will work. The same signal travels bidrectionally between all connected devices; when you issue a command every device receives it and then determines if it was intended to it.You can also use a custom cable with the CEC pins (13 & 17) split out but this is a far less practical solution for most people since an improperly shielded cable will likely degrade the signal anyway.

Was the missing link that let me control my PS4 from iRule (Android home theater universal remote app). Will be adding some more cec devices to my system, and this should allow me to control them as well. Yay! :)I write a 5-star review because for *me* it was perfect. However, the included software is extremely limited. Really, out of the box, without a bit of your own code, it basically only serves to pass XBMC remote functions along to your TV and receiver - which is really useful, but only scratches the surface of what it could do.However, the hardware has the capacity to send and receive any command to any connected CEC device in your system, and the libcec library that interfaces with it is open source - so if you need more and you've got a bit of programming experience, it can do so much more.
