    Im using a usb port hub and somtimes after i come out of standby or restart everything connected to the hub stops working. I have to unplug the power supply for the hub and plug it back in for it to start working again. I did not have this problem once with 98SE but it has been happening constantly since i upgraded to xp. any ideas?

    Look into start\settings\control panel\system\hardware tab..Device manager...Now look in the USB option..Now right click inn on the USB device you see inn the inn on properties,,

    Now i do believe that the device u are using have a POWER MANAGEMENT option...take a look in there..

    alll that properties page tells me is that the hub is self powered.....i doesnt say anything about turning it off when not in use

    Hi I had the same problem. In device manager under USB Root Hub there is a power management tab, when you open that there is a box that says "allow your computer to turn off this device to save power" Take the tick out of the box.

    sweet.....i thought i checked that, but apparently i didnt.....hopefully it does the job. Im only a bit skeptical cuz the hub is self powered -> not controlled by windows

    thanks for pointing that out

    I've got a simular problem but it wasn't solved bij unchecking the box "allow your computer to turn off this device to save power" ..

    I do not have a self powered usb hub, but one wich uses the laptop's power. It is a 4 port hub.. Every time I restart my laptop I have te disconnect the USB hub and reconnect it te be seen properly. Before doing so it shows in the USB devices thread an unknown device. After reconnecting the usb hub it shows Generic USB hub.

    This problem did not acure with Win98SE. But now running WinXP..
