Bluetooth keyboard mouse switch

Как подключить к Switch клавиатуру и мышь

Да, это возможно! И хотя сама идея поначалу может показаться абсурдной, так очень удобно вводить пароли, комментировать фото и даже играть в некоторые игры, например, Fortnite. Теоретически можно подключить ихдаже к Switch Lite!

Поддерживаемые клавиатуры

Со Switch совместима большая часть USB-клавиатур, но играть с обычной клавиатуры не получится. Однако, с них можно вводить пароли и любой другой текст (например, названия игр в поиске eShop). Многие считают, что физическая клавиатура гораздо удобнее экранной.

Некоторые компании делают специальные клавиатуры для Switch со слотами под джой-коны по бокам. Но играть с такой все равно нельзя, так что особого смысла ее покупать я не вижу.

Как подключить USB-клавиатуру?

Для подключения USB-клавиатуры достаточно включить ее в любой USB-порт на док-станции. Консоль должна обнаружить ее автоматически, никакой дополнительной настройки не требуется. К сожалению, такое подключение позволяет только вводить текст (например, названия игр в eShop или пароли) – играть с ней нельзя.

Вы можете пользоваться клавиатурой даже в портативном режиме при помощи переходника с USB на USB-C, и даже подключить беспроводную клавиатуру через Bluetooth-донгл. А вот подключать к Switch стандартную игровую мышь бесполезно – работать не будет.

Выход есть!

Но все не так страшно! Есть специальные комбо из кейпада и мышки, например, Gamesir VX AimSwitch (устройство официально поддерживает Switch, а еще Xbox One, PS3 и PS4) или Delta Essentials, которое практически не отличается по функционалу, цене и даже дизайну. Адаптер для подключения есть в комплекте.

Уже имеющиеся девайсы можно попробовать подключить через USB-адаптер, например, от HYCRUS, C91 или Delta Essentials. Кроме того, можно использовать комбинацию двух адаптеров: Cronusmax Plus GamingAdapter и какого-нибудь адаптера PS4-WiiU, например Gam3Gear Brook, однако, по деньгам такая хитрая схема примерно эквивалентна покупке AimSwitch. Но если вдруг эти устройства у вас уже есть – имейте в виду.

Can I switch a bluetooth keyboard/mouse via a USB KVM switch?

I have two Ubuntu machines in a closet, and a USB cable coming out from there via a Video/USB switcher. My keyboard, mouse, a tablet screen, and USB audio are all hanging off the far side of the Video/USB switcher. That all works great for wired keyboards and for a couple of wireless mice. However if I try to use a Bluetooth mouse and keyboard, one system (running Ubuntu 18.04) works fine, but the other, running 20.04 does not. The 20.04 machine sees the Bluetooth adapter (and using my phone I can see that machine advertising itself when I go into the Bluetooth settings page). However, the 20.04 machine won’t pair with the keyboard, and doesn’t even seem to see the mouse. The keyboard is capable of pairing to multiple devices, but I don’t believe the mouse is. Is this some limitation on Bluetooth? I was hoping the keyboard and mouse would pair with the USB adapter rather than with the machine behind it, but it seems that’s not the case. Can anyone tell me what I should and should not be able to make work? And does anyone else run Bluetooth keyboard / mouse to multiple machines behind a switch? If so, how do you handle this?

What is the model of the Bluetooth mouse and keyboard? While keyboards may be able to pair to more than one at a time, it may not be able to control more than one at a time. Plus, why would you want to send the exact same keyboard commands to both systems at the same time? The only other thing I can think of would be to get a mouse and keyboard combination that connect to their own wireless receiver, then you could plug that receiver into the switch instead, that way it hits both systems when you switch back and forth.

I’m not sending the keyboard to both at once. The USB bluetooth dongle is on the far side of a KVM switcher that also switches USB. So, I was hoping the keyboard would connect to the USB device, and then by switching which machine that USB device is connected to, I want to connect the keyboard to one machine at a time. The KVM/USB switcher does something I don’t fully understand so that it does not appear to the computers as though the USB devices were unplugged and replugghed, just that they didn’t do any communicating while the USB was connected to the other machine.

Oh, the bluetooth is built on Broadcom BCM20702A0 (it’s branded ASUS). Keyboard is a Keychron K2, Mouse is a logitech M535.

So, how would you tell the Bluetooth devices then when you switch between systems? I don’t think you can. A KVM breaks the connection to one system when you switch to the other. You would have Bluetooth on both that is active all the time so there would be no way to tell the keyboard and mouse what system you’re switched to.

I think I’m not explaining. The USB bluetooth dongle is on the keyboard side of the USB / KVM switcher. It gets connected to one or other computer at the same time that I switch the screens, by the same device. That device switches HDMI and USB. Other USB devices (such as my USB audio) switch just fine. And when I switch to one or other machine, that machine sees the bluetooth, and appears to be able to advertize its existence (I can see the computer, through bluetooth, on my phone) But the keyboard and the mouse do not work.

KVM Switch Wireless Keyboard & Mouse Guide

Using a Wireless Keyboard / Mouse with a KVM Switch

As prices drop and new wireless technologies are developed, wireless keyboards and mice are becoming more and more common in home and business environments. Unfortunately, due to the differences in the way in which wireless devices communicate, choosing the best KVM Switch for using a wireless keyboard and mouse can be daunting. Beyond compatibility issues, very few KVM switches on the market explicitly state support for wireless devices making selecting your switching infrastructure difficult.

Best KVM Switches for Wireless Keyboard & Mouse

There are two main types of KVM Switches that can support controlling sources with a wireless keyboard and mouse. While neither KVM type guarantees support for wireless devices, the underlying technologies theoretically allow you to use them.

1. KVM Switches with USB Hub

Some KVM Switches feature peripheral USB Hub ports. These ports let you transparently plug in and switch USB devices between connected computers. These KVMs often support Wireless devices with some extra configuration.

2. KVM Switches without USB Emulation

In order to support ‘Hot-Key’ and uninterrupted keyboard-mouse operation, most newer KVM Switches Emulate USB Keyboard & Mouse signals. While this Emulation is typically desired, it can interfere with Wireless devices. Some low-cost KVMs still ship without Emulation, and some other models let you toggle this feature in settings.

Please Note
Unless a manufacturer states explicit support for a Wireless Keyboard and Mouse model, we are unable to guarantee compatibility in a specific environment.

Connecting Wireless Keyboard / Mouse to a KVM Switch

In order to support Hot-Key operation and uninterrupted keyboard-mouse function while switching, most KVM Switches have a chip that constantly buffers (reads) signals from the keyboard and mouse, and transfers any button presses to the connected computer. This feature is known as ‘Emulated USB’ or ‘Emulated Mouse & Keyboard’. While this emulation works great for wired devices, wireless devices use a different data transfer protocol that is not compatible. This is the main cause of problems when using wireless devices on a KVM, as the KVM switch will only relay signals that it understands to the computer.

Though on some occasions wireless combos will function on a KVM switch that uses emulation, this is highly unusual and is entirely dependent on the user environment. If you are currently attempting to use a wireless device on a KVM, or have your mind set on a KVM that uses emulation, there are a few options that may make your wireless devices function properly.

Proceed step-by-step through the following possible solutions until one works for you:

1. If possible, turn off USB Mouse & Keyboard Emulation in settings.
2. Plug the wireless USB combo receiver (I.e. Logitech Unifying Receiver) into the keyboard USB port, and leave mouse USB port empty.
   • If this doesn’t work, try to plug-in the wireless receiver into the mouse port, and a separate wired keyboard into the keyboard USB port — you can put this keyboard aside and use the wireless devices instead.
3. If the KVM has one or more USB 2.0 or USB 3 Peripheral (Hub) sharing ports, the wireless USB receiver can often be connected to one of these ports.
   • Some KVMs require a wired keyboard to be connected to the KVMs regular keyboard USB port to function — you can put this keyboard aside and use the wireless devices instead.
4. Un-install the driver for the wireless device.
   • Sometimes the proprietary driver for a wireless device can interfere with a KVM, and compatibility issues can be solved by using the native driver included in the OS instead.

Please Note
— The KVMs USB specification must be USB 2.0 or greater; USB 1.0 doesn�t have enough bandwidth to support 2 wireless HID devices from 1 port.
— After initial connection, wireless keyboard response may take 10-15 sec. Response delay after subsequent switches usually takes 4-5 sec.
— When using a Wireless Keyboard & Mouse with a KVM Switch port switching will typically have to be done using the physical port selection buttons on the KVM unit, an On-Screen-Display menu, or a separate wired keyboard.
— These steps may not work for your application. Unless a manufacturer states explicit support for a Wireless Keyboard and Mouse model, we are unable to guarantee compatibility in a specific environment.

Things to consider when choosing a KVM Switch for use with Wireless Keyboard & Mouse

While ‘Emulated USB’ is typically the root problem, there are various other factors that may cause issues. There is no de-facto standard when choosing a KVM switch for use with wireless devices, however the following is a general list of things to keep in mind when choosing the appropriate KVM:

• A KVM Switch with Transparent USB -USB without any kind of emulation- is more likely to support wireless devices natively without having to use a separate USB Hub port.
• Slight voltage fluctuations may disconnect your wireless devices occasionally, especially while idling or switching. There isn’t much to do about this, but typically we have seen better results with higher quality KVM devices.
• Over-IP KVMs will always utilize USB Emulation; While some KVMs may support wireless devices via a ‘USB Virtual Media’ (USB Peripheral Hub ports over IP), we do not typically advise using a wireless keyboard & mouse with a networked IP KVM.
• Wireless devices with individual dedicated USB receivers have a better chance of working on a KVM than a wireless keyboard & mouse combo (2 devices) with a single shared USB receiver.
• The KVMs USB specification must be USB 2.0 or greater; USB 1.0 doesn’t have enough bandwidth to support 2 wireless HID devices from 1 port.
• When using a Wireless Keyboard & Mouse with a KVM Switch port switching will typically have to be done using the physical port selection buttons on the KVM unit, an On-Screen-Display menu, or a separate wired keyboard.
• After initial connection, keyboard response may take 10-15 sec. Response delay after subsequent switches usually takes 4-5 sec.
• This guide may not work for your application in getting your Wireless devices to function with a KVM. Unless a manufacturer states explicit support for a Wireless Keyboard and Mouse model, we are unable to guarantee compatibility in a specific environment.

Wireless vs. Wired Keyboard & Mouse for a KVM Switch

If your mind set on a Wireless Keyboard & Mouse, it may be possible to find a KVM Switch solution for your application. However, with the drawbacks of switching delay, not being able to use Hot-key switching, and common compatibility issues even when using the steps above, we would still always recommend using a Wired Keyboard & Mouse with a KVM Switch for the best user experience.
