Any idea if this can be used to display nook's screen on a tv?
http://www.dealextreme.com/p/micro-...-adapter-with-usb-charging-cable-black-140197
It would be really cool if it did, but as far as I know the Nook does not have MHL.
A micro USB connector is only five pins, but if it's implemented in the device they can be switched between:
USB peripheral or host interface
Analog audio headset with microphone
MHL video output
Debugging UART serial port
Unfortunately, the Nook has only been proved to support the USB interface.
USB to VGA
well I have seen these USB to VGA on ebay
could this work?
It would be very interesting to get a USB to video adaptor working.
It might be a long road to getting it to mirror the Nook screen transparently.
The first step is to find something with Linux drivers.
The next step is to get it to expose its frame buffer on the system.
At that point, it would be possible to make an application to copy images between the two frame buffers.
Even that might have some utility for Power Point style presentations.
nook PC?
sounds plausible. would be also nice to be able to use Nook like PC.

1. So I've heard that a HDMI cable works the same way as the HD dock, does it let you open theater mode(forgot the actual name) or hdmi mirroring with just a cable?
No mirroring yet. Theater mode pops up as an option when plugging in a HDMI cable. with a long enough cable it works as a great remote control.
2. Does the 'Theater' mode play video that was not created on the device?
Yes, but you should check the supported codec list on motorolas website, I have had some problems with some obscure audio codecs.
3. Does the Android window in webtop mode let you scale the app or is it a fixed size?
Yes its scalable, but there is borders on the screen that prevent it from stretching to the entire screen
4. Has anyone tried using storage(such as a keydrive) or wireless keyboard/mouse(2.4GHz not bluetooth) in the usb ports on the HD dock or the Laptop Dock?
FAT32 usb drives seem to work, haven't gotten to try a usb 2.0 hdd. Wireless 2.4GHZ peripherals work fine.
so HDMI mirroring is out i know that but still havent been able to test any of the rest of this in my trip to AT&T, as someone had locked the fingerprint reader to their print lol
Is it possible to use the micro USB audio connector for audio? After rooting, the audio application of the android does not recognize the mp3 files to play. Why not let it do so?
I think that would require USB host mode like on the Samsung galaxy. I think that means needing extra hardware doesn't it? -otherwise I would expect every phone to be capable of it
edit: It is possible but you can fry stuff. Info on NookColor forum
USB host = great possible enhancement?
I wanted to post to proper thread, however I am new here I was not allowed to post on developers forum. So I hope that this post will still somehow find its way there. It also includes your original question.
Since some USB features are now claimed to be working, I wanted to ask directly poping out questions:
http://forum.xda-developers.com/showthread.php?p=21669750
Is it possible to...
1.) disable on-screen keyboard while using USB one?
2.) connect USB soundcard like: http://www.usbgear.com/computer_cable_details.cfm?sku=USBG-X2X&cats=121&catid=121%2C136%2C134
To allow listening mp3, Skype calls.... ?
3.) connect USB Ethernet card like: http://www.usbgear.com/205528.html
4.) to connect other cool usb stuff like: GSM, printers ... whatever
thanks you developer guys, I hope I'll once manage some time to learn more about the system and developement so that I could contribute too !
thanks to androind and nook simple touch creators!

Currently the answer to all of the above is no
The USB host mode patch was done for a specific project (USB keyboard support) and while I have been spending some time playing around with Bluetooth I'm not aware of any other dev(s) working on expanding this atm.
Stuff like audio, networking and Bluetooth requires _a_lot_ more than just the kernel accepting to communicate with the device.
thats shame. allowed skype calls would be great
Skype calls are working on my nook with OTG + USB audio card on usb host mode. But it is a bit difficult ))).
To update these older posts:
Yes, it is possible to disable the soft keyboard when using a USB keyboard.
See NullKbd in the signature.
Yes, Skype works fine.

Where is the difficulty?
Do a logcat and look for overruns and errors.
There were a few mods done to make Skype work.
so an external usb sound card is working?
Yes, an external USB audio adapter can work.
As a portable solution it's a bit cumbersome.
I don't know what current they usually draw, but my cheapy one draws 75 mA.
A desktop solution with powered hub (charging the Nook), a USB adapter and speakers works fine.
Would USB headphones work directly on that port? I have USB OTG cable and some USB sound card somewhere so I can check with regular 3.5mm jack headphones without trouble when I find some time to do it but I just wonder if anyone tried USB headphones on it and what they think of it. Is it worth of a hassle to buy one for NST?
Some USB devices use a multiplexor on the USB micro connector and can send actual analog audio down the connector.
Many Androids support USB host mode and can support an audio USB adapter, including the ones that go for < $10.
The NST (earlier Nooks with OMAP processors) don't have complete software support for USB host mode but can be coerced into working.
The Glows (later Nooks with IMX processor) don't have complete software or hardware support for USB host mode but can be coerced into working.
The Glow4 (7.8") has audio.
Anyone know if a USB to DVI (any video) will work with the TFP? Would like to put together a make shift docking station with Monitor, Keyboard, Mouse, etc. Would like to run all of it through the USB port though.
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.
Hi!
Please, give me advice how to find out problem root with some USB devices that can't be detected/used with my android device.
There is device like car rear view mirror with android. Phisung E06 or any of exactly same devices under different Chinese brands. Every device have touchscreen, front view camera, rear view USB (!) camera, one SIM card LTE, GPS and mini USB connector. Rear view camera connector is 2,5 mm mini jack instead of regular USB connector. miniUSB connector is for power supply and for firmware update from PC. These devices are based on MTK MT6735 chip that have only one USB port (as you see there is two USB connectors and only one phisical USB port) and 2 . Android is 5.1 Lollipop. Кernel version is 3.10.65+
I run dmesg in android console and found following. miniUSB port is connected to MT6735 regular USB port whereas USB camera is connected to inter chip USB port that normally used to work with second SIM card. I soldered DIY 2,5 mm mini jack to USB female adapter and tested it. With USB active hub with external power supply and my DIY adapter I successfully connected and used rear view camera, keyboard and mouse . They are work well. However USB card reader and U-BLOX USB GPS reciever are not detected by android. So I used USB Device Info app to check how my devices are detected by kernel USB subsystem. I was able connect hub to hub to hub and plug my devices to any port of them.
-USB Device Info app on the kernel tab view always give correct HUB hierarchy and point of connection hub/port of camera/mouse/keyboard and it's detailed info (vendor, name, etc.).
-USB card reader is shown too connected but none of my SD card recognized. No info in USB Device. No SD Card files in any of subfolder of /storage folder.
-U-BLOX USB GPS reciever was not detected at all. It's power indicator is lit still. GNSS Commander can't use reciever showing it's offline status. (P.S. Reciver is OK. It is used with PC and OTG port of my android 5 tablet)
The question are:
- why SD card is not detected in card reader
- why U-BLOX USB GPS reciever is not detected at all
I expect both of them are requre data to be recieved from host to control usb peripherial device. Unlike, for example, camera or mouse who do not require any data from host.
Please, advice me what log I need to check, what special apps I need to run, what adb and console commands can help me.
Thank you

could you plz send me the Preloader because I f*ck up my system and format the whole system :S
