USB HUB, Receiver & Keyboard

Step 1:
Dell sells technology such as computers, computer peripherals and consumer electronics to both consumers and businesses. Dell sells both wired and wireless keyboards and mice that are compatible with Dell and other computer systems. Dell wireless keyboards may encounter hardware, software or other problems under certain conditions.

Power Dell wireless keyboards transmit data to the Dell USB receiver, which in turn passes the data to the computer's operating system. The keyboard gets power from two AA batteries. As the batteries lose charge, the keyboard's transmissions can become intermittent. Replacing the old batteries with fresh ones will ensure consistent communication and resolve the power issue. b> Interference Dell wireless keyboards operate best and are least susceptible to interference when the user places them at the recommended distance from the USB receiver. The distance, specified in the keyboard's accompanying software or installation guide, varies by keyboard. Even if the user places the keyboard at the proper distance from the USB hub, metal objects between the keyboard and hub can create interference; moving objects that create the interference resolves the issue. b> Connection The Dell USB receiver that passes data from the keyboard to the computer requires proper and secure installation in a working USB port. If the receiver connects to the USB port improperly, or if the USB port to which the receiver is connected is faulty, the keyboard will not operate as expected. The user can reseat the receiver in the USB port, or connect to the receiver to a different, functioning USB port to resolve connection problems. b> Synchronization Dell wireless keyboards can broadcast at more than one frequency, just as their associated USB receivers do. If the two devices broadcast at different frequencies, they will not pass information to each other. The user can resolve this situation using the buttons labeled "Connect" on the top of the receiver and the bottom of the mouse. Pressing the buttons simultaneously triggers the synchronization process. b> System Dell wireless keyboards are compatible with most Dell systems. However, a keyboard may be incompatible with a given computer for reasons related to the computer rather than to the keyboard. To determine if this is the case, a user can connect the keyboard to a different computer. If the keyboard functions as expected with the second computer, the problem may reside in the first computer rather than in the keyboard.

Well i'm having the same problem.
My mouse & keyboard work trough the hub, however when i plug an USB-stick in, it wont recognize it.

I've i put my USB-stick in another USB-port, it works.

So try putting your usb, in another USB-port, thats not from your hub.

If all the keys on the keyboard have stopped functioning follow the instructions below to reconnect the keyboard.

This problem is likely to be a lost connection. The connection between the mouse and the USB mini-receiver or the keyboard and the USB mini-receiver can be lost due to several reasons such as:

• Low batteries
• Moving the USB mini-receiver from one USB port to another
• Moving the USB mini-receiver to another computer
• Plugging the USB mini-receiver into a USB hub or other unsupported device such as a KVM switch (your USB mini-receiver must be plugged directly into your computer)
• Using your cordless mouse/keyboard on metal surfaces
• Radio frequency (RF) interference of more powerful wireless devices such as:
  • Wireless speakers
  • Computer power supplies
  • Monitors
  • Cellular telephones
  • Garage door openers

Eliminate any problem sources mentioned above that might be affecting your devices.

Follow the procedures below to reconnect your mouse and keyboard.

1. Make sure the USB mini-receiver is directly and securely plugged into a working USB port on your computer.
   
2. Make sure the mouse is turned on. The on/off indicator on the bottom of the mouse should be green. If the on/off indicator is not illuminated, press and hold the red connect button on the bottom of the mouse until the on/off indicator is green.
   On / Off Indicator
   
   
3. Press and release the red connect button on the underside of the USB mini-receiver. This will broadcast a signal to your mouse. This broadcast will last only a few seconds, so you must perform the next step quickly.
   
   Red Connect Button
   
4. Quickly press the red connect button on the bottom of the mouse for 1 second, then release it. The power indicator will flash briefly and then turn green. The mouse is now connected to the receiver.
   
   Red Connect Button NOTE: Holding down the red button on the mouse for more than 2 seconds may cause your mouse to turn off instead of connecting. If this occurs, start again at step number 2.
   
5. Move your mouse to see if the cursor moves. If the cursor follows the mouse movements, your mouse is now connected.
   
6. Press and release the red connect button on the underside of the USB mini-receiver. This will broadcast a signal to your keyboard. This broadcast will last only a few seconds, so you must perform the next step quickly.
   
   Red Connect Button
   
7. Quickly press and release the red connect button on the underside of the keyboard.
   Keyboard Connect Button
   
8. You will hear a short beep. The keyboard is now connected to the receiver.
   
9. Test your keyboard to see if it is working. If the mouse now works but the keyboard still does not, see Knowledge Base article 9144.
   

There are 4 possible ways in my awareness...
Method 1: Resynchronize your device with the receiver To resynchronize the mouse or the keyboard with the receiver, follow these steps. Note When you synchronize the mouse or the keyboard with the receiver, put the device near the receiver and put any other wireless keyboards and mouse at least 6 feet away.

1. Press the button on the receiver, and then verify that the light on the receiver starts to blink.
   
   Note Some newer Microsoft devices are permanently bound to their receiver and cannot be reset. If your device does not have a button, skip to Method 2.
2. If a dialog box appears on the screen in several seconds, follow the instructions that appear on the screen. Otherwise, go to the next step.
3. Press and release the Connect Channel button on the bottom of the mouse or the keyboard.
4. Check the green light on the receiver. A steady green light means the synchronization was successful. If the problem persists, try steps 1 through 4 again.
5. For the Wireless Notebook mouse: This issue can occur if the micro-switch on the bottom of the mouse is not released. Use a pin or a pen to try to release the button if it is depressed.

The following example shows the buttons to push to synchronize a wireless hardware device:

USB keyboard and USB mouseIf the USB cable is currently connected to a USB hub, disconnect the device from the hub, and then connect it to a USB port on the computer. If your device is already connected to a USB port on the computer, try to connect the device to a different USB port if one is available.

Note Only one USB connection to the computer is required, even if your device has two USB plugs. If the problem persists, disconnect other USB devices and connect only the USB plug from the receiver to a USB port on the computer. PS/2 devices Warning If you have to change a PS/2 connection, shut off the computer, make the changes, and then restart the computer. Do not plug a PS/2 device into the PS/2 port while the computer is running.If your devices are connected to PS/2 ports on the computer, verify that you have the following configurations:

• Verify that the USB plug for your mouse is connected to the green USB-to-PS/2 adapter and that this adapter is plugged in the mouse PS/2 port on the computer. The mouse PS/2 port on the computer may also be green. If you are not sure which PS/2 port is the mouse PS/2 port, see the documentation that was included with the computer.
• Verify that the USB plug for the keyboard is connected to the purple USB-to-PS/2 adapter and that this adapter is plugged in the keyboard PS/2 port on the computer. The keyboard PS/2 port on the computer may also be purple. If you are not sure which PS/2 port is the keyboard PS/2 port, see the documentation that was included with the computer.

If you have to change your configuration, shut down the computer, make the changes, and then restart the computer. If your mouse or keyboard has both USB and PS/2 connections, try using the other connection. PS/2 keyboard and USB mouseIf you are using a wireless mouse with a USB connector and a PS/2 keyboard, verify that the USB mouse is plugged in a USB port on the computer and that the purple keyboard PS/2 plug is connected to the purple PS/2 port on the computer. If you have to change the PS/2 connection, shut off the computer, make the changes, and then restart the computer. Method 3: Reinsert the batteries or install fresh batteriesBoth the wireless keyboard and the wireless mouse rely on AA alkaline batteries for power. Remove the batteries, and then insert them again. If the problem persists, install a fresh set of batteries in the device that you are having problems with. Method 4: Check for interferenceItems such as wireless routers, radios, cell phones, desktop fans, fluorescent lights, and large metal objects like computer cases and metal furniture may interfere with the signal of the keyboard. Try to keep such items away from the keyboard, and check the behavior of the keyboard.

Do not put the mouse or the receiver near any electrical devices, especially transmitters such as cordless or cellular telephones or other wireless mouse devices or receivers. A distance of at least 8 to 12 inches is recommended. Do not put the mouse or the receiver on metallic surfaces or objects, especially long metallic rails or cables. We recommend that you keep the mouse and the keyboard a minimum of 3 feet from metallic objects.

This might help and might not. Check in system to see what devices you have on the same usb hub. The more things on the same hub the less power that goes to the transceiver for the mouse and the keyboard. Ideally if you can just connect the one thing to the one usb hub and try to leave it alone from there.
Hope this helps.

Did you press the connect button located underneath your keyboard and still didn't work?

• It might need some cleaning?
• Also check if is a key that has been stucked. Sometimes, removing keys and putting them back on will solve the problem.
• See if the USB bluetooth is connected properly.
• Check under the Device Manager. You might also need the Logitech updated driver???

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.

The MS keyboard & mouse receiver is effectively a USB hub with two devices connected to it. So, plugging it into the keyboard socket on the KVM switch may well work, depending on how that particular switch implements USB. If it just passes things through, it should be OK. On the PC side you should only need to plug in the USB cable from the switch's keyboard port.
