Hello jaybear

The most likely problem is your USB bus is underpowered for supporting your external hard disk drive along with other USB devices.

First, this is actually a good thing in a way. The reason is, it is actually telling you right up front that your USB bus is underpowered for this device. That's a huge improvement over issues caused by underpowered USB buses in the previous model computers. In those, we were left to having to figure out what the problem was when a USB device inexplicably stopped or didn't work.

What is happening is, your new hard disk drive(s) (HDD) are trying to run off of power supplied by your computer's USB "bus" (circuitry). This is OK for USB devices needing low power. But in the case of external hard disks, it's "iffy" whether there'll be enough power on the USB bus to support even one of them, much less two or more. Particularly on laptop computers.
Have no fear. This problem is easily remedied. :)

You need only attach an A/C adapter to each of your external hard disk drives and you should be OK.

If that is not an option, connect a **powered** USB hub to your laptop and plug the external HDDs into the hub instead.

By "powered" I mean a USB hub that comes w/ an A/C adapter. In either case, using a powered USB hub or attaching an A/C adapter to your hard disk drives will remove the external hard disks' power load from your laptop's USB bus and provide sufficient power for the HDDs to run.

You can find USB hubs at Newegg.com and lots of other online high tech stores. I like Newegg because their prices are competitive, their customer service is excellent and there're customer reviews of most of their products there as well.

If you have any more questions, comments, observations - anything at all, just let us know. We're here to help.

Otherwise, PLEASE, take a moment to rate the solution that best addresses your problem. If the solution provides a "fix" for your problem, then a **FIXYA** rating would be very much appreciated. :)

Thank you

    This solution applies to laptop and to desktop computers. I was making the assumption that yours was a laptop as that is where I see most issues w/ low power on the USB bus. The remedy is the same in either case.

    Hello jaybar. I take the rating and your having closed the problem as good news - that my recommendation(s) corrected your issues and all your external USB devices are co-habitating nicely on your computer now.



    Fantastic!

Keyboard stopped working


http://www.ascendtech.us/emachines-kb-0705-ps-2-keyboard-black_i_kbdemkb0705bps2.aspx

Things I see here.
1) The second Keyboard you plugged wasn't any good either.

2) The PS/2 port for your keyboard on your motherboard, isn't any good anymore.
Computer off, plug it into the Mouse PS/2 port, and use a USB mouse.
BIOS will reset the I/O address for that PS/2 port, and set it for the Keyboard, when the computer is turned back on.

You may have to;
A) Turn the computer off
B) Unplug from power.

C) Press the Power On button in, and hold it in for a count of 10 seconds. Let go of the Power On button. Do this same procedure two more times.

What you are doing is draining residual power, clearing CMOS Error Codes, and resetting BIOS back to the factory default settings.

Keyboard plugged in, USB mouse plugged in, plug the computer back into power. WAIT 1 minute, turn the computer on.

Still no?
Motherboard replacement.

You didn't unplug the old Keyboard, WITH the computer on, and plug the new Keyboard in, did you? It isn't a hot-swap device. The computer must be off when unplugging a mouse, or keyboard.

For additional questions please post in a Comment.

I cannot get my keyboard or my mouse to work with my dell computer. what can i do?


Please add more information to get specific assistance. Are these wireless devices? If wired, do they use USB or PS/2 connections.

For wireless devices, try replacing the batteries and resynching to the receiver. (You may want to check putting the receiver in different USB ports.)

For wired devices, disconnect and reconnect. For PS/2 devices, you will need to restart the computer to check if the devices work. For USB devices, try connecting to different USB ports.

Next step, try using a different keyboard and mouse (that work on another computer (stick to USB or PS/2 to match the current pair)). Try a wired set if the problem is with a wireless pair. If those work, continue diagnostics on the wireless keyboard and mouse. Check if the mouse and keyboard work on another computer. If they don't work with another computer, replace them.

If another USB keyboard and mouse pair don't work in any port, your USB ports may have failed. Check if even one port works enough to access the Device Manager. (Start > Control Panel > Hardware and Sound > Device Manager (Win7); similar directions in other versions of Windows) Check for a problem with the drivers (For USB ports, scroll down to the USB drivers and look for a triangle with a yellow exclamation point or red x). Try to update the driver or roll it back. If that doesn't help and one USB port works, a USB hub may solve the problem.

Otherwise if the USB or PS/2 ports do not work with any devices and the driver fix doesn't work, then I'd suspect a problem with the ports on the motherboard. Replace the motherboard/computer.

I hope this helps.

The microsoft wireless mouse stopped working after a power failure. I get a message that says the USB device is not there. But I cannot navigate my computer w/o the mouse


The Microsoft wireless mouse comes with a wireless receiver, right? Before you do anything, the first thing that you can try is to replace the batteries with fresh ones.

If same problem occur, try to connect the wireless receiver into different USB ports of the computer. Then check if your wireless receiver and mouse has a connect button. If it does have connect buttons, briefly press the connect button on the receiver, then hold down the connect button on the mouse for 5 seconds. Then release the connect buttons.

If you get the same problem, hold down both connect buttons (receiver and mouse) at the same time for 5 seconds.

Last, try to connect the wireless receiver into different computer. If you get the same problem, send the receiver and mouse to the manufacturer for repair.

Thank you and good luck!

My usb ports stopped working . i can;t download music to my ipod. i've tried all 6 of the usb ports with same resukts


Have you tried a different cable? If the cable is custom, sorry you will need to buy a new one to try it.
Plug in another USB device. Is this OK?
Do you use a USB Mouse? Try all the ports.
iPod cables are easily damaged. Ipod docks can be broken by force, twisting or dropping. Insert the iPod into the dock at the correct angle, gently.
Take care to insert the iPod cable straight, right side up. Do not drop the iPod with the cable inserted.
A foreign object like lint, dirt, paper or hair may be stuck in the connector. NEVER clean the connector with a metal object. Use a toothpick, carefully.

Two devices stopped working after plugging them into a powered usb hub: a laser usb mouse and a wireless network adaptor. Both were working fine when plugged into a regular usb hub. Got the powered hub...


the two device wont have any issue. but i would suggest to connect the ext. hdd directly to the sys. and it requires more power, and hub does not provide that much power which is required for ext hdd. you can try to connect only the ext. hdd to hub and check.

After rebooting my cpu my mouse stopped working. My cpu does not recognize my mouse? The mouse works because i tried it on a different cpu. what can be causing this?


Did you try to reboot?
Do you have an optical mouse? (if yes: is the red light on?
(Then the mouse is recognized and you must configure your mouse options)
Did you try to connect your USB mouse to another connector?
Or if PS2 connector: Turn of the pc and connect the mouse and power on.
Did you install a new driver? (then uninstall this driver)
Try looking for the most recent mouse driver on the manufacturer site.

Wireless mouse not registering with my computer


When you plug the receiver into the computer, what happens? Does Windows see the device? If it does not then the device may be defective. Most cordless receivers plug into USB ports. Try different USB ports.

Hi sdd555,

Restart the computer after plugging the USB keyboard into a different USB port, or remove the keyboard in Device Manager and then refresh the system to work around the issue. This will cause the device to be re-enumerated and the driver will be reloaded.

Good Luck,

Mouse problems


Usually this happens whenthe software for the usb ports' controller is not as current as it should be.
check your computer manufacturers' website for and updated driver. USB 2.0 is what you are looking for. This can work in reverse also , if you are using a legacy USB device (mouse) and try to use USB 2.0 devices on the same controller it can cause problems as well. A new USB mouse is inexpensive, but always check the BIOS and make sure all USB ports are running and that the controller is enabled for them with current drivers.
If you post the computer make and model number i can be more specific with my advice.
Please post again if you need further assistance & thanks for using fixya..
Regards.
