    Computer Cable reliability in an automotive environment

    I have been trying to get my new fully 'puter running... having some cable issues.

    In this case... video cable issues. These are touchscreen cables, with integral USB connections as well.

    I had one DOA right out of the box (no USB touchscreen functionality). Another one lasted about 4 days before it developed what is most likely an internal short and made my PC reboot every few seconds.

    While I am waiting for more cables to arrive, wondering if it is just be, or do other people have cable issues in an automotive environment? I cant blame the first one on my pickup... it didn't work right out of the box. The second one... not sure... it might have lasted for years sitting on a desktop.

    What are other peoples experiences with cables?

    Lots of issues with cables here, mostly USB cables.
    What I have learned so far:
    - Buy quality ones that are a bit more expensive. Thick ones are better than thin ones.
    - Some cables (even thick ones) have crappy connectors that dont offer good contacts and even cause short circuits if you move the connectors too much.
    - Try to avoid connecting several cables together. Only use one cable from one device to the computer if possible.
    - Avoid USB hubs, buy motherboards with enough USB ports instead.
    - Check your needed length properly. Dont use cables that are far too long and keep distances as short as possible.
    - USB 3.0 cables are even more likely to cause problems than USB 2.0 ones.
    - Secure connections against vibrations.

    Just to expand on my 13 word comment b4...On board usb header pins are nice also..ive used Some of mine..i have some 8mm heavy insulated audio cable that i use for usb cables.i have been desoldering usb connectors on hubs and dongles and soldering the cables directly a good dose if heat shrink and its super solid..those run to the header pins..total pain when if and when the pc was to be removed but much more reliable than even good quality usb cables...
    In my 4x4 vibration and shocks has been a real killer in the past.right now i have a "device not recognized" issue with a really expensive powered hub..im sure the hub is the problem but could well be the cable as it isnt one i have rebuilt.will be pulling it very soon.
    Totally agree with Gullimonster about not using hubs too..but somtimes you just need one...or 2

    Of course. I count those headers in as USB ports of the motherboard.

    You can easily find motherboards with 12 ports (incl. headers), and some even offer up to 16.
    If you need more than that, then yes, I guess you will need a hub.

    I like your idea of soldering your own wires. Maybe I will go that path some day too. Right now I have an issue with my camera, it sometimes shows up as not recognized device. I already shortened the cable, and it has pretty much solved, but it seems to still happen from time to time. However I am out of options. The cable cant be shortened any more and the cable is the best quality I found. I guess the problem is the stock cable on the camera, because its very thin.
