Περιγραφή:

The Logitech Unifying Receiver is a USB plug that can listen to several computer peripherals. A single plug can be paired with one mouse, and one keyboard. It should be noted that newer Logitech products support Bluetooth. This is useful if you for example forget or drop the Unifying Receiver USB plug. However, Unifying Receivers can be purchased separately. Note that the following devices are vulnerable to MouseJacking attack when they are connected to the Unifying Receiver: K360, K400r, K750, K830 (source)

Solaar (instead of Logitech's proprietary Unifying Software) "is a Linux manager for many Logitech keyboards, mice, and trackpads that connect wirelessly to a USB Unifying, Bolt, Lightspeed, or Nano receiver; connect directly via a USB cable; or connect via Bluetooth." solaar is packaged for many distros! A typical use case is that you can set the DPI to higher values than your desktop environment allows.

Pairing

The Logitech Unifying Receiver is paired with the hardware that it ships with. However, USB plugs can be paired and unpaired with some Logitech branded mice and keyboard with the recommended software.

Experience With Gnewsense-Parkes

If this receiver-wireless keyboard solution is used as the primary method of data entry in a setup in which the root mount point is inside an encrypted partition, the receiver doesn't work between its use in the Grub Menu and the loading of the modules by the Operating System, preventing the decryption password from being entered, stopping loading of the Operating System. In order to fix that, append these lines to /etc/initramfs-tools/modules

:
hid_logitech
hid_logitech_dj
#One of the above may not be alway be required and my produce a warning
And per instructions on the file itself, one must run update-initramfs for the change to take effect. If the changes didn't seem to take effect, verify that the kernel configuration file in /boot/ have the following values equal to "m" as in "module". CONFIG_HID_LOGITECH=m CONFIG_HID_LOGITECH_DJ=m [/p]
