    Hi all,

    Does anyone have any direct experience with USB3 cables over 5M? I brought a 8m active cable which has additional usb power lead which I've plugged into a mains adaptor.

    I have my keyboard attached to this cable and its causing an issue in typing where it's missing keystrokes or hitting extra keys. The keyboard was working before i introduced this cable so its the only thing i can put it down to.

    Are usb over Ethernet adaptors any good and if so can anyone recommend a good one?

    What is your application that you need 8m of cable? There might be other alternatives?
    I haven't directly worked with USB 2.0 over Ethernet but I have co-workers that have in an industrial setting. There impression was that it was finicky and not all manufacturers created equal goods.

    Sounds like a dodgy cable to me. 8m isn't that far. A cheap 5m USB 2.0/3.0 active cable without a separate power supply should do the job. Just add a shorter decent quality non-active extension after the active one (say 5m active>2/3m passive>device cable).
    Active usb extensions shouldn't (and haven't in my experience) cause a problem with mouse/keyboard input.

    Computer now sits on the wall further from where it use to. I'd decided to wrap the usb cable round the side of the room to where i sit.

    Have you considered wireless? Depending on condition you should expect 5-10 meters with Bluetooth or Logitech's unified receiver. That will be line of sight rather than wrapped around the edge of the room.

    i use to have a K800 but it lost a few keys so i replaced it with a cabled keyboard.

    i switched to a gaming keyboard and at the time couldn't find a gaming keyboard that had what i wanted and was wireless

    Does your keyboard computer support PS/2? I don't recall the length but it supports fairly long cables. Not sure how that translates if you use a USB to PS/2 adapter.

    I bought a very long USB3 cable for my rear Rift sensor. Can't remember the exact length I ordered but it must be in the region of 8m at least as there's plenty of slack left.

    Anyway, it was an Amazon Basics USB3 cable and I've never had a problem with it.

    so after some further investigation and a fluke i believe i've found the issue :( The keyboard itself is a corsair RGB keyboard and with it working fine beforehand i didn't think it would be the issue.

    i thought in the first place that it might have been due to lack of power coming from the cable so i plugged in a powered port replicator that i had to see if that would make a difference but it didn't. thought it might have been the cable so i picked up another one and that was the same.

    Then as i turned the computer on later on that day the keyboard didn't light up but was still usable and it looked to be working fine.

    i re-seated the keyboard usb cable and the issue came back. managed to try in another computer and that was working fine over the cable.

    i then went about and Killed the icue software and the issue cleared itself. restarted and the issue came back. so it looks like icue doesn't like the setup :(

    which means that to have a fully working keyboard i'd have to stick with a single static colour profile that sits on the keyboards memory

    I'm sure you solved it....but still, just in case.

    Are you sure your keyboard needs USB3?
    If USB2 suffices, i can highly reccommend the DELOCK 82446 active USB 2 Extension.
    Doesn't need an external power source and is 10m and works like a charm in industrial enironments.
