Targus Travel USB 2.0 4-Port Hub with Notebook Light
My Targus Travel USB 2.0 4-Port Hub with Notebook Light stopped working on my hp pavillion dv6000 (running vista). there appears to be no power going through it and i've verified that it's not the port. i really liked this hub and am disappointed it's stopped working.

Right click on my computer or the icon for my computer and select manage then open device manager and see what it says in there then up top select check for hardware changes icon, this should look for and install the hub
This USB hub is not powered by an AC adapter. Therefore, some devices that need more power will not work well on it. You don't mention what it is you are pluggin into it, but I suspect this may be your problem. Devices like webcams pull way too much to be on a hub without AC.
Did I solve your problem? If so, please rate this. ty.
on my computer right click and select properties, then go to the device manager. Under the USB device locate this device and delete and unplug the cable from the computer. Let the computer reboot, and plug the cable into another port if ava. and see what happens.
sometimes usb hard drives will not work through a usb hub.
if the drive works connected to the laptop but not the hub then that's how you'll have to use it.
it's also possible the laptop cannot power both the hub AND the drive, in whaich case you'll need a powered hub (one you plug in to the mains).
Check your hardware from CONTROL PANEL / SYSTEM / HARDWARE.
Also check HP's support section on the web for any updated drivers especially for your laptops motherboard / bios
Any exclamation marks by hardware need fixing before you investigate any further
Once you have done that try some of the common fixes below.
I devised these simple steps that tend to remedy quite a few issues with most USB portable / external hard drives and devices (though not always)
A few things to check but assumes USB and Windows for other interfaces / operating systems similar steps may be adapted to suit.
1. Ensure it is connected directly to the computer to a USB 2.0 port not a USB 1.0 port as this can have effects on performance and reliability
2. Use only the cables that came with it NOT one that fits that may have been lying around or is longer. Not all USB cables are equal even though they should be)
3. Do not connect through an external USB HUB unless that hub is USB 2.0 AND has its own power supply.
4. Use ONLY the power supply that came with it if it has an external power supply Don’t use any other unless you know it has both the same voltage and current rating e.g. 12V 500mA anything rated below that would not work properly.
5. Always use the same port for connecting your devices. Some devices do not like being switched about. If switched they may want to install software / drivers again. This can be especialy true if you move a HUB to another port
do one thing boot ur vista without usb hub then go to device manager remove your usb drivers of the hub disconnect the hub from computer, restart notebook, then connect the hub back when windows boot let vista to install the driver of that hub, after that connect your devices one by one ok let me know what happen? :-)
If you have an option to turn off USB charging for the camera try this and see if it will work then assuming that all you really want to do is transfer files. If not, then you'll need to switch the camera to a direct USB port on the computer or buy a powered USB hub.
Most USB hubs do not need an external power supply, except when a connected USB device draws more power than the computer/laptop USB port can supply. In this case an external power supply will need to be connected to the USB hub. Normally this would be a 5 volt power supply, but make sure the polarity on the connector matches the power connector on the hub, check the label on the hub, sometimes it states to power requirements of the hub as well as the polarity on the connector. Normally the pin on the hub's power connector is positive (ie. +5V)
