If you see something wrong with the device everytime you plug in something to the USB hub doesn't necessarily mean that the hub is defective but it may actually mean that the device may not be receiving enough power to make it work. As we all know USB a device that may or may not have its own power but at least we know its working when by check the light indicator on the device or checking in device manager and that is an indication that it may or may not work with a hub and may need to be directly connected. If device you hook up is working with direct connection try isolating it by hooking it up from one port on the hub to the other this may actually help you out determining if there is defective port on the hub otherwise you got a lemon any may to return the product as well consult with them which product have they tested that actually worked with it.

My pandigital e book has died completely,It will not come on. I have had it plugged in but the red light will not light. It is dead. What is wrong?


I would start by checking the ac adapter to make sure that it is working using a multimeter or voltmeter. You can probably take it to a computer shop and get them to test it for you. If the AC adapter is working, then you'll likely need to have the device serviced.

I PLUGGED MY MP3 PLAYER INTO MY LAPTOP USB PORT AND IT USED TO WORK NOW IT SAID THE USB DEVICE HAS EXCEEDED ITS POWER LIMITS OF ITS HUB PORT AND WONT WORK NOW


If you get an error message"Insufficient power to operate USB device" when you plug a USB deviceinto the computer's USB port, then this device is drawing excessive currentthat the USB port cannot supply. The maximum output from an USB port is 500mA. In case such as this, youneed to purchased a powered USB hub and connect this hub into the computer'sUSB port and then connect the USB device into this powered USB hub.

My usb ports do not work. Memory stick works on other computers but not my desktop. Help!


Do any other devices work on any of your USB ports on the desktops? Does the memory stick work with a port that works for another device?

If all of the ports fail, check the Device Manager (for Windows OS) - you may have a driver issue. This is reached through the Control Panel (under Hardware or System). The exact titles will depend on the version of the OS.

When you scroll through the list to the USB controllers, look for a triangle with a red x or a yellow triangle. The right click (or double-left click) and try to update your driver or roll back the driver to an older version that worked.

If only a few ports fail, then are you dealing with the front ports or the rear ports? If the front ports (case), then you might want to check if the header cable is fully connected to both the case and the motherboard. This requires opening the case with the appropriate care.

Unfortunately, some new USB devices pull too much power through the port and can burn them out. (Those that charge on the computer are the most likely culprit.) If you have a few working ports, get a USB hub that is self-powered. (Get a good one or only use the AC adapter when there are more than 4 devices connected to the hub.)

I hope this helps.

Hi there, It sounds like your problem is that you haven't hooked up your front USB ports to your motherboard. If you open up your computer case, you should notice some cables coming down from the front USB ports. Those cables need to be attached to USB headers on your motherboard. You should check out your motherboards manual to see where the pins for the USB headers are, and then hook up the cable. My guess would be that no USB device works via the front panel, but after hooking up these cables all devices, including your external hard drive, will. If you need more help/clarification, let me know please! Alex

Hp paviilion will not power up


try removing the battery and switch on your notebook using the ac adapter only if it works then i think you need a replacement for the battery or you can try to power cycle your notebook i hope it applies to hp notebooks coz it works all the time with dell vostro. to power cycle: unplug/remove ac adapter, battery, usb devices (mp3, ipod, printers, etc) optical drive, network cable then press and hold the power button not less than 10 seconds then put everything back except for the usb devices and network cable if it works then you can plug everything back again.

see heres the thing when using VM-Ware, VM-Ware doesnt use drivers for your physical hardware, because it emulates the hardware that is seen in the hardware information of your system preferences.

So installing even drivers for the "emulated" hardware will not work, as VM-Ware uses its own drivers for the hardware, which are included with the VM-Ware Tools, if that doesnt seem to work, you may want to contact VM-Ware support, as they may have a better solutiuon.

ECS GeForce 6100SM-M usb issues


Hello,

Like always I'm sorry for I have to be the one who's giving the bad news. The problem you face is related to a complex issue with the keyboard and mouse receiver electronics. More precisely these devices emulate a standard ps2 interface but adapts it to work with a usb port. This emulation should work fine but has some limitations. A motherboard has some 2-4 usb main ports that can be hard wired to some 1-2 usb hubs mounted also on the motherboard. A urb hub has the advantage of replicating a usb port so more then 1 devices can be connected at the same time, sharing the same interface. Motherboard manufacturers use this to enable their products to have more usb ports available to the user. However there are some devices that aren't compatible to be used through these usb hubs and must be connected directly to a usb port in order to use the full bandwich. Wireless keyboards and mices, or usb to ps2 adapters are such examples. As hard as you may try these woun't work untill you replug them at every restart because they can't be properly initialised through a usb hub. most of these devices have been optimised for such uses and don't display such problems, but as you see not all of them.
The only solution in your case would be to change the usb port where you plug these devices. Maybe your motherboard has some 1-2 usb ports that aren't run through a usb hub. Those ports would work fine. If this doesn't help, then there's no other way to make those 2 devices more "compatible" to eachother.

Hope you'll be lucky with finding the right usb plug in your motherboard. Just try every one of them, reinstall the drivers if needed, and check to see if this solves the problem.
