I'm trying to connect a camera to get the files off it but my phone doesn't allow me so to select anything else but the charging of the connected device option (the camera doesn't even supports USB charging)? How can I fix that?
if you want to see if USB OTG works, you could try a normal USB memory stick before to try the camera
if the stick works, the problem is the camera
Well a mouse works fine..and the camera does work with Android 8 Devices. So no.

Saw a new app to tether your Canon camera to your phone instead of a computer.. Gives you all the controls like when you tether to your PC, but on the phone, still in beta, and only tested on xoom and sgs2.. but i saw that the phone needs USB host support for it to work.
Is this something the Atrix can have with the roms now?
This would be sweet!
yes. in order to use USB host you just need to provide 5V DC to the device which the Atrix's usb port doesnt do. you will need to use a powered USB hub. check out: http://forum.xda-developers.com/showthread.php?t=997187
drivers will probably be an issue though

That does sound sweet Shriva! What's the name of the app and if it was not in the general app market where was it?
Thanks,

Atrix 4d and 2 support USB host mode when you use OTG cable and provide power (you can use mouse, keybaord storage etc.).
But it does not support Androi API support for USB host mode. Which means Apps won't detect any device thus DSLR camera control apps don't work. Maybe with update to ICS it will be supported.
Hi,
Can somebody verify otg connection is working for this tablet?
I tried my cable but it does not turn the device into usb host mode.
A quick test with a usb host testing app showed that this tablet has no usb host capabilities. Shame.
BS - of course this tablet has USB host functionality.
Via the usual OTG adaptor you can connect the usual USB sticks, hard drives (with own power supply), mice, keyboards etc.
It has even a special feature (can be activated in audio settings) for connecting a USB DAC for high-quality sound / recording.
Yes, it works w/o problems

Cool, looks like that test app isn't very accurate then.
This is the result it came up with:
If @datalkingx means with OTG connection to connect USB Flash Drive, Keyboard, etc. then it works, if he means something else then I don't know

Not all devices works some memory card reader don't work.
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.
Ok, so has anyone else had problems with this..
when you plug in an OTG connected usb device (i have the same problem with usb drives and midi controllers so far) and in the notification bar pull down it will say charging usb device, and when you choose to switch it to something else, like transfer files or connect a midi device, it just goes right back to charging the device after changing it for a few seconds or until you tap the screen or check it again.
This has completely stopped me from being able to connect a midi device, and causes the usb drives to get hot, although I can still transfer files in an 3rd party file manager, but the notification bar will never stay in tranfer mode, and it has never gone into midi mode at all.
This is not an issue with my OTG adapter, as I also have the same problems with borrowed adapters, as well as using DEX. In fact in dex, if I plug in a usb drive and switch to transfer files mode it will crash. Has anyone else experienced these problems? Are any of these apps for OTG management in the play store useful for this? They seem to be useless based on the reviews except for testing a UTG adapter. Thanks!
btw I don't have root, my note 8 is fully updated to BQLA version.
Hi, check the battery! If internal resistance goes up so does noise.
Check the cable and connector on the phone as well.
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
