    Powered USB HUB

    Hi All, Please kindly help.
    Have purchased a Canyon CNR-USBHUB06N and connected it. Now after I have shut down my
    PC, the power light remains on and if I try to start the PC again nothing happens. I have to turn off
    the the wall socket for the Hub before the PC will start again. Does this mean I will always have to turn off the
    powered hub first before shutting down and why would this be?
    Can I connect another powered device to a powered USB HUB?
    Many thanks
    Dave

    Some hubs don't talk nicely to the PC, yours seems to be one of those - but it may be your PC.
    You can daisy chain hubs, but I reckon you should just buy a bigger hub.

    cheers, Paul

    Thanks Paul
    If I don't connect the power supply for the Usb hub then when I shut down my PC then the power button on my PC goes off and the pilot light
    on the hub also goes off. A usb device works if I connect it to the hub without the hub power connected. When you mention buying a bigger hub is
    this a powered one?

    Have had my power supply replaced and this has fixed the hub problem.
    Thanks

    A power supply for a USB hub will never hurt, it can only help, because without one, you may not have sufficient power available on the USB line to power the devices that are connected to the hub.

    However, as you have found, if your power supply is bad, then it can and will "hurt".

    I never buy a USB hub unless it has its own power supply.

    How did you work out the power supply was dodgy?

    cheers, Paul

    I returned the powered hub to where I purchased it from and asked them to test it on one of their machines.
    It worked fine, so I took my PC to them to test and they found the PC power supply faulty and replaced it.
    A few days before the fan on the power supply had suddenly become very noisy, so I'm not sure if this had
    caused a problem in the power supply. My knowledge of PCs is very limited.
    Regards
    Dave
