Hi,
I want to control my Motorola Moto Z Play over USB Debugging with my Notebook. The Problem is that I must confirm that the Notebook is trustable, but my Touchscreen doesn't function. So I must confirm it with a keyobard or mouse after I connect it with the Notebook.
I testet a USB Hub: Smartphone -> OTG Adapter -> USB Hub -> Notebook (usb male to male cable) + Keyboard.
The Keyboard has functioned and my phone was charging, but the confirm button doesnt come. I also couldn't see the phone as an adb device.
Can I solve this Problem or do I have to buy a new screen?
Best regards
motozmod
And what exactly is your laptop?

[SOLVED] Android Tablet -> OTG -> USB Hub -> Gaming keyboard/mouse not working
Greetings.
I can plug an external-powered 4-port USB hub to Kiano Core 10.1 Dual 3G and it is recognized by the system and USB Device Info app. But as soon as I connect a gaming mouse or keyboard that simulates an USB hub (with mouse and keyboard attached to it so you can bind keys to mouse and clicks to keyboard), the system freezes and only unplugging the hub or waiting some time (if only keyboard is plugged to the hub) can help. After waiting some time, the system unfeezes and the app recognizes the keyboard. About the mouse, it completly freezes the system and only a hard reset helps.
On my Galaxy Note 3 and Xperia P, the hub, mouse and keyboard work without problems.
Both mouse and keyboard work with the tablet if plugged without the hub (mouse is recognized as both mouse and keyboard so I cannot use the on-screen keyboard, but this is another problem).
I have a rooted original rom.
Can anyone help with this?
EDIT: USB pendrives work on the powered hub. The problem may be considered solved, because I found another unpowered USB hub and both mouse and keyboard work on the unpowered hub.
Hi all, I have a MK809III tv stick with Android 4.4.2 running. I use it as a mini PC with a LCD screen. I have attached to its USB OTG ports a quadrate 2.0 4 ports USB HUB (google for this and you can see it) , and connected to it, a PS/2 keyboard (using an usbtoPs2 adapter), an usb mouse, a usb ethernet dongle, and a usb sound card dongle. When I use this combo, all works fine, the mouse can drag and select, also wheel works, the keyboard works fine, the ethernet run smooth, and the sound works as player and mic recorder, the only thing not works is to reboot the tv stick, and launch android again (with other MK89III tv stick this also works flawlessly), to get this, I must to unplug RJ45 or usb ethernet. But this last question is not my main problem. The main problem is that I can not make the combo work anyway if I change usb hub model, If I use a 2.0 usb square hub (no name brand) with a little blue led installed, all works fine, but using other hub (I have tested two others), thare is no way to work. The main situation is that the hub stops work, and all item connected not works at all. But commonly, mouse works with a bad behaviour in button response, usb sound disconnects suddenly, or usb ethernet lagg or not works at all. My question is about this behaviour with usb hubs, if there is a special requirements in hardware to match an usb hub with this kind of android devices, or if thare are some drivers that can solve this.
Thank in advance.
Solved
I have solved the two main problems in order to use my MK809III RK3188 as a mini pc with usb hub and rj45 ethernet. The hub must to be a chip on board one, no an all-in-one glued ultra-cheap type, this is a mark of better quality and response, then you can conect keyboard/mouse, usb or ps2 with usb converters, usb sound, and usb pendrives. The ethernet must be an ASIX AX88772C, this a true usb ethernet 100mbps (7MB/s real) device, since I use it there is no lag, no boot errors, no delays or shorts in Tx/Rx. That´s all.
I bought a Rapoo e6500 portable bluetooth keyboard
https://www.youtube.com/watch?v=mvim6Gh4hR0
It works perfectly in wireless with either my Android tablet or with my desktop computer
However, it also has a mini USB port (for recharging)
But if I switch BT off and connect it via USB it does not get recognized at all
How come?
Could it be that the USB connection carries only charge and no data?
If I connect it to a linux running computer and give the command lsusb the keyboard does not show up....
Android doesn't work like that. Only charging and mtp protocols are the only ones.
Welcome, i need to connect mouse via usb, or game pad, i got that adapter otg, but nothing works, no mather what mouse.
Is there a ROM with OTG on kernel or some drivers or tricks?
Like i mentioned in the other thread, maybe, if you attach the mouse to an active hub. Unlike the drivers for usb OTG, those for mouse and keyboard could already be present in the rom or keyboard app. And you need mains for this, not really a portable solution.
i recently brought a OTG Cable & USB Hub so i can Connect my Wired Mouse & Keyboard to my Device, i first test the OTG Cable with the Mouse Only to test if it works, and it does, then i Switch to Keyboard, which also works, so then i Connect the OTG Cable to the USB Hub and Plug the Mouse and Keyboard to the Hub, the problem is only the Mouse were Connected, not the Keyboard, i tried Unplugging the Mouse from the Hub, the Keyboard still won't connect i want to be able to use Both Mouse and Keyboard on my Device, if someone can help me with this, I'll really appreciate it, thanks!
