I am looking for a Dongle

Unfortunately, EN 60950 is not a Logitech model number. It indicates that the mouse (or other electronic product) was tested and met the European IEC 60950 standard. Here's a copy of a Logitech EN60950 certificate: https://www.logitech.com/images/pdf/compliance/AGY-700-018651.001_AGY%20CERT%20CB%20HS%20A00086%20BAER%20CI%20(GGEC)_EUROPE.pdf .

Logitech sells several different wireless mice types. Some connect to Bluetooth only. Some connect with a specific USB wireless transmitter/receiver. The dongle is small enough to fit inside the mouse's battery compartment or stay in a USB port when the laptop is moved. (Older Logitech devices used the Unifying USB wi-fi adapter; new ones use the Bolt adapter.) A few models can be used with both Bluetooth and one of the wireless adapters. These can connect to two or more devices and then a single button switches between devices.

Please try to find the actual model of the mouse to get the correct information for connecting the mouse. Logitech support may be able to sell you the USB dongle if they have the correct one in stock.

I hope this helps.

Unfortunately you're missing some important information to receive detailed help. Particularly the model of the mouse you are using. Some models are specific to the dongle and are unable to be paired with another dongle. There are some that come with a dongle, but can pair with a computer/device's Bluetooth connection. There are even models that can be paired with different dongles of that specific manufacturer, and you just have to look on Amazon, eBay, etc. for a replacement dongle. You'll have to check with the manufacturer of the mouse to verify. Or reply with the model of the mouse that you are trying to use.

You should search for small wireless USB dongle (receiver) and insert it into USB port of your laptop. You bought The dongle with mouse. Sometimes it is placed inside mouse on bottom side. See picture.

A mouse driver is usually installed automatically in a while after the dongle is connected to PC.

The thw wireless mouse is paired from fabric wirh USB dongle for same mouse. You can't connect a wireless keyboard to it because they are no different frequency. Actually it's hightly improbable that you even could connect the USB dongle of a mouse with another different mouse. Explanations is logical: presumeyou are in a big office whate another 1 users have wireless keyboards or "mice". Now, imaginge the mess if the dongle of your keyboard should control the mouse of another 9 usrs.
Now, it's competely different with bloetooth keyboards and"mice"

Each One Will Need Separate USB Dongle (receiver)

csr 4.0 dongle?
what does that mean.?

my guess is the wireless mouse batteries are dead, then...
on HP wireless USB receiver is dead. or lost. (or wrong one used)
or drivers for it missing, (get them at HP.COM)
mouse has bottom switch ON/OFF, , ON is best.
rare most, see lots sold used with no receiver at all. sad that.

Hi

Without the dongle, the mouse cannot communicate with the computer. Only logitech produce a dongle with the correct signal to connect to the mouse.

So either order a replacement dongle from logitech or buy a 2nd identical cordless mouse set and keep one mouse as a spare, in case the first one is dropped, becomes faulty or gets lost or temporarily mislaid.

I hope this helps.

Ths problem occurs because of usb drvier conflict issue with your usb wireless dongle driver. For that go to device manager uninstall all usb drivers then it will automatic install all driver. Then go to control panel->add remove program and features then uninstall your wireleless keyboard and mouse driver then reinstall. Then restart and check. Also try different usb ports of computer for connecting the usb wireless dongle of keyboard. Let me know if you need further assistance. Thanks for using FixYa.

Most Logitech wireless mouse are just Plug-n-Play and it does not require any driver installation. All you have to do is to plug the wireless dongle to the computer and connect the mouse. Here's what you need to do:

1. Make sure that the batteries are fresh or fully charged.
2. Turn ON the mouse using the switch button.
3. Locate the connect button on the dongle (receiver) and then press it once.
4. Hold down the connect button underneath the mouse for 5 secs. and then release it. And the mouse should work.

If the mouse is not responding, then hold down the connect button on the dongle and on the mouse at the same time for 5 secs. and then release them both. Move the mouse around.

Hope this helps and have a great day!
