[Q] How to use USB Keyboard with Motorola Atrix

Hi
I have following questions:
1) How do I use Computer USB Keyboard with Motorola Atrix ?
2) Is it possible to connect Motorola Atrix with Laptop and you can use Laptop Keyboard and Laptop Screen to see and use everything in Atrix without using Motorola Webtop laptop ?
Thanks

In the Atrix Development forum you'll find a hack that allows you to use the Atrix webtop on any monitor/TV with HDMI. Pair a bluetooth mouse and keyboard with your Atrix to use them on the webtop. Works great here, didn't even require root.

Also, if you have a HD multimedia dock, you can plug a USB mouse or keyboard into the available USB ports in the back of the dock. It works well!

see above post, that's what I am using (I forgot to specify that it was USB wireless), a Logitech (can't remember model number) wireless USB keyboard and mouse. works perfectly, even the volume buttons, etc. on the keyboard.

If you're not using the HD multimedia dock (via the Webtop hack), then no, you can't use them as there are no USB ports you can plug your receiver into. You will have to settle for bluetooth devices.

Callen81 has a video that shows how USB hardware can be connected to the Atrix. It requires soldering two connections, and a powered USB hub, but it can be done.
HDMI mirroring, from what I can understand from your broken English (I'm not hating, but it's true.) is not possible on the Atrix (yet!). You can, however, see the mobile OS from webtop mode in a separate window. And on the laptop, you can plug in USB keyboards and mice to the ports in the back.

actually mirroring was enabled (see dev forum), but it's not as easy. it also will only show portrait mode (no landscape)

Yes, and the point is that it's still got the same, if not worse, performance that it would have on Webtop mode. At least, I think.

If the Atrix can read USB sticks (?) then would plugging a standard USB stick, which has a USB1-typeA-plug on it, require a converter that was a "USB1 Type A recepticle" converting to a "USB2-micro-TypeB-plug?
Would that be the correct nomenclature for the USB adapters, and does anyone know if you can buy that premade, or whether the Atrix absolutely will or won't recognize a USB stick that way?
I'm also looking for some USB2-micro-TypeB-plugs either on or off a wire, to try adding the drop resistor to pin 5 so I can tell the Atrix "You're in a car dock now" or just "you're in a dock now" and force it into the other modes.
I'll probably roll my own car dock, mainly because I want my Atrix (in an Otter Commuter) to be secured in the dock. Really secured, so if I flip and roll and total out the car, the Atrix is still exactly where I left it. The spring-clip jobbies will turn your phone into a missile if someone whacks into you, making calls for help impossible.

ATRIX USB port

OK so we know that the ATRIX rocks. Able to dock and serve 720p video and all that to a external monitor. And while using the Multimedia dock or laptop dock you can even plug in external USB devices. My question is this. Should the phone be able to handle that natively?
What will happen if I plug in a external USB switch will 2 way communication function?
Will an external keyboard be recognized?
Now that we have WEBTOP without the dock I think it would be great to have a keyboard without Bluetooth.
As always your comments are appreciated in advance.

Yes, I believe USB Host Mode is enabled by default in the stock kernel.

See this topic. There is all you need

This is not development.

Sorry did not know where it went.

How livedock activates landscape in the home screen

Hi, so the Livedock is pretty cool but looking at the price of it I decided it was too dear so I set out on creating a cheap option. I purchased an OTG USB TO Micro USB as well as this pretty cool suction pad phone holder off ebay
Everything works great (keyboard and mouse connect flawlessly so all good) however one thing I noticed in the livedock videos is when they plug the phone in the homescreen goes into landscape mode, and I am trying to figure out how to do this mannually. The only current possible way to do this when plugging it into the TV via HDMI, but I would like to know how the phone knows to rotate when the livedock is plugged in is there an application I can install to make it do this.
ta and to anyone looking to hook up their keyobard and mouse or gamepad I'd recommend this very cheap option!

Smart Dock + Tethering?

Has anyone found a way to tether through one of the Smart Dock USB ports? I'm interested in using the data from my phone but don't want to use the Hotspot function (don't want to root or pay for HotSpot so I wanna use tethering).
This Smart Dock was alot more finnicky that I had thought. For those having trouble, for me at least, HDMI and anything you're connecting via USB have to be plugged into the dock before you dock your phone to get anything to work. I also have to plug in the HDMI to get the USB ports to work which doesn't make sense to me but what do I know. I was surprised the dock doesn't have the full Micro B connector which I thought was necessary to have MHL and USBOTG at the same. If that's not the case, I'm not sure I understand what the extra pins are for on the Micro-B plug. My screen also automatically shuts off when I dock with HDMI, not sure if that's a "feature" or not.

Maybe it's my model number. I got the EDD-S20EWE. I notice the current one is S20JWE. Or maybe the $60 sale on Amazon got me a knock-off. In any case, there's no way in heck I could recommend this thing to anyone. Too finnicky. One of those gadgets you gotta hold your tongue right to make it work like its supposed to. It works when it wants to for me. I'm driving myself crazy unplugging and plugging stuff back in and restarting things to make it work.
If you want a desktop experience like me, instead of this thing, I'd recommend Screen Mirroring, bluetoothing to keyboard/mouse, and either tethering your data if need that like me, or adding the USB Connector dongle for any other USB items you need. Much less headache from my experience. YMMV.

Dex without dock

Is it possible to use dex without the official dock. For instance I already have (Samsung Multiport Adapter (EE-PW700BWEGUJ)) this dock for the Samsung windows tablet.

I hope it does so we dont have to spend $150 on top of spending $850 for the phone.

Very doubtful

I have a suspicion that DeX is just a much-upgraded version of SideSync. It required an application on your PC to show your phone screen in a window. So my best guess is that DeX dock acts as a client app, like SideSync on your desktop was. So, if that's truly the case, I doubt DeX will work with multi-port adapter.

Dex doesn't require a PC . You have to connect it directly to display and input devices such a mouse or keyboard. So you are using it instead of PC.
In my opinion this is just a HDMI adapter with separate USB hub, network socket, and cooler. I maybe wrong, but if im right it should be very easy to connect it in PC mode without Dex or with cheap replacement.

This was exactly the point I was trying to make. SideSync required an app on your PC. DeX' idea of replacing your PC will probably require a similar "app" to run on the dock, in order to force a full desktop.
If S8 does support video out through USB-C port, it may be just a simple screen mirroring. Or, who knows, you may get full DeX experience!

Could this app be an option/solution?

Im sure once we have custom firmwares and so, someone will make it mock dock able and then all we have to do is cast the screen or usb type c to hdmi?

I'm also wondering this. Samsung Sells a USB-C to HDMI adapter for this phone.

I want to get one and try with something called a Pi Top to build the dex into that. So we could have a dex laptop.

I hope so. the phone puts out displayport over usbc, but the dock dumbs it down to hdmi which IMO was a dumb thing to do. They should have passed through the displayport over usb signal instead. Far more flexible.

Well I just bought a USB-C to HDMI with charging port and USB port, I will try it out once TMO ships my phone.

It's probably going to be a simple part/resistor/chip that lets the phone recognise the dock, will probably see clones and alternative solutions on eBay soon enough.
Can't see the dock serving any actual function that stops you from launching Dex without it.
I could be wrong.

Certainly could be some encrypted key or something that makes it more difficult to emulate. Part of the cost of the Dex unit might be for the development of the software for it, even if it is included in every S8.. you need the Dex to unlock it.

So the Galaxy S8 does support USB C HDMI TV out via any HDMI adapter as I have tried.
However, it just mirrors the screen and the DeX experience is no where to be found without actually using the DeX dock!

I can confirm @khurram87 I get the same, screen mirror and no Dex.

Yep tried it with my Samsung hdmi + usb to usbc adapter. Just Hub and Video Out.... LAME.

I plugged my phone into one of these. No desktop.
I am assuming the Dex dock has some firmware which installs on the phone when docked. Someone with a rooted Exynos S8 may be able to pull those files and create an application which would launch into Dex-mode.

Manufacturers just can't seem to resist the urge to take a standard interface and stick some proprietary something on there to restrict your options.
A few years ago it was chargers (standard mini/micro USB charger, but device refused to charge in anything but that manufacturers approved chargers) - both for phones and even PS3 controllers.
Now it seems to be HDMI adapters/docks. The S8 apparently requires the DeX dock to enter desktop mode, despite that dock being nothing more than a standard USB-C dock beneath the surface., though at least HDMI output without the DeX software still works with it. The Nintendo Switch in comparison only allows HDMI output with the official dock.
I hope somebody comes out with a third-party adapter that works with both . . .one travel adapter to let me play the Switch on the big screen, or use my phone as a pseudo-laptop would be a must-have travel accessory compared to the over-priced single-purpose official docks.

^this!
