I feel like a blonde. What occurred was that I placed an order for a keyboard "at the same time" for a second computer that would be connected to the television. We required a PC-compatible device that was both portable and wireless. The keyboard arrived, and upon opening it, I discovered that it did not come with a BT adaptor. Now that I've got that out of the way, I'll open Logitech, and in order to connect any devices, I'll need to use the Logitech Options software. I download it, and when I launch it, it informs me that there is "No USB Unifying Receiver found." I take a look, and it turns out that this is a Logitech adapter; Logitech Easy Switch is supported by it; the same inscription was printed on the box of the keyboard, so I decide to order it. The object arrives, and there is no reaction to it. I'm starting to get the hang of this; I can now see that the adaptor is not Bluetooth-enabled, but the keyboard is. This letter is being written in support of 2022 and English. Support for 2022 provides no responses to any questions. My main language of communication is English. The final response is: ". Denis, It has come to my attention that you possess an additional method, namely the utilization of the bluetooth adapter, for connecting the Logitech K380 multi-device. I would like to warn you that Logitech does not recommend connecting the devices using any adapters, cables, or extenders manufactured by third parties because doing so may cause the devices to malfunction. This is something I would want to inform you of. You can, however, utilize the Bluetooth adaptor in order to create the connection between the device and the system; nevertheless, doing so will be entirely at your own risk. " I translate: "Denis, It appears that you can connect your Logitech K380 to other devices by using a Bluetooth adapter as an alternative method. I am writing to let you know that Logitech does not advise connecting devices by making use of any adapters, cables, or extenders manufactured by a third party because doing so has the potential to cause device malfunction. However, if you want to make a connection between your device and the system, you can utilize a Bluetooth adaptor to do so, but doing so is entirely at your own risk. Logitech produced a keyboard, declared that it could connect to a personal computer, did not include a low-cost Bluetooth adapter in the packaging, does not permit you to purchase your own branded adapter, and claims that it confuses with its Easy-Switch in various contexts. Additionally, Logitech asserts that you can only use third-party Bluetooth from a personal computer manufacturer, but you do so at your own risk. Logics! Investigate the product in great detail.
