Kick back and navigate your TV-connected computer from the comfort of your couch. PC-to-TV entertainment shouldn’t be hard work.
#How to connect logitech wireless keyboard to tv k400r windows#
Note that I initially testes the K400 on Windows where it was fine and did not exhibit any of these problems.LAID-BACK CONTROL OF YOUR PC-TO-TV ENTERTAINMENT One more systematic problem I have found is that even with mouse speed and acceleration set to max in LXDE, it still takes endless stroking on the pad to get the mouse pointer across the screen. The K400 is rated at 100mA so is perhaps a bit marginal when plugged in directly. Before I did that, the keyboard (and WiFi) problems were much worse. I did have some problems getting a power supply that worked reliably and in the end cut the connector off of a 4Amp USB hub PSU and spliced a micro-USB cable to it.
It does not seem any more responsive with the WiFi removed however. I am using it with an Edimax Nano WiFi, both plugged directly into the RPi, and both the same size - very neat I only have a power and HDMI cable. The touch-pad works, including two-finger scrolling and double-tap gestures, the two-finger scrolling and mouse-buttons however seem somewhat unresponsive at times - probably the same issue as the sticky keys - perhaps the RPi is interfering with the RF signal and it is dropping data packets. I am going to try to partially work around it by setting the keyboard auto-repeat as slow as possible (when did anyone ever need that in any case!?). I think in fact it just as frequently misses a key-down, but that is far less annoying so perhaps underplayed as a symptom. It seems as if it sees the key-down but misses the key-up event. I have not seen the sticky key problem on the command line, and it seems responsive enough in a LXTerminal window too. I am not sure if it is LXDE in general or Midori specifically, but the CPU usage often goes to 100% in Midori, so that may have something to do with it. However, I mostly see it only when using Midori. The "sticky keys" issue seems common, I am certainly experiencing that. I have the K400 working out-of-the-box with debian6-19-04-2012 without any specific configuration of the RPi. Keyboard works: Yes, but with sticky keys Power Source: HP Touchpad charger - 5.3V at 2.0A Perhaps we can also get a standard fix or set of instructions for owners of this popular keyboard.ĭistro: Debian “squeeze” 19-04-2012, with updated boot files (to fix SD card compatibility)

Then maybe we can come to some sort of consensus and update the Verified Peripherals page on eLinux, and avoid having people buying keyboards that aren't compatible. If you have tried a K400 with your Pi, please post in this thread and vote in the poll to let the community know what your set up is, what level of success you've had, and if you had to work any Linux magic to achieve it. When I try to reconfigure the keyboard, it comes up as a Generic 105-key, and (although there are a lot of logitech keyboards listed) the K400 is not an option I can choose. My own keyboard works, but I get some sticky-keys and my touchpad doesn't work at all.
ith-linux/ among others claims that the K400 works out of the box with Debian.
The wiki page lists this keyboard as working, but there is no mention of the touchpad. I have read several posts from users on the forum who have the Logitech K400 wireless keyboard and seen varying levels of success being reported.
