[Q] Android usb dac and beginning - Android Q&A, Help & Troubleshooting

Hello,
I have a google nexus 7.
Some questions:
1. Where do you find which android version I have on my nexus 7 ?
2. I guess it downloaded 4.2 yesterday.
3. IMPORTANT:
I bought a otg cable to be able to attach a usb device, in my case a usb-dac fiio E7.
As I don't plan to root my device (I have no root access says somewhere , how come ?) is there anybody who can tell me when usb/dac (fiio
E7) will be supported ? I saw that 4.2 would support usb audiodevices. I don't see any results.
I'm not keen at installing kernels and stuff to make it heapen. My opinion is that that the android os should provide support for usb dacs.
4. It seems I have no proximity sensor, can't select it and get the message not installed. Is this normal. Bought on amazon uk, couple of months
ago.
Enough apps, but little support on questions like mine.
Thanks for all help.

[Q] OTG/USB Host for MT65XX Phones, especially for Jiayu G3, possible?

Hi folks!
I need the OTG/USB Host function on my Jiayu G3. Normally it doesn't support it..
So I did i lot of research and tests at "how i can enable it" and found some information:
1. some things point to it, like the libusbhost.so in /system/lib
2. all 5 pins of the usb slot are connected to a chip (this says nothing, i know)
3. i have found a pdf, which says that otg is possible on mt6575-77 (found on github)
So my question, has anybody get otg/usb host get enabled on Jiayu G3 oder m65xx phones? OR is anybody there who want the same like me and helps me to make it possible?
OTG unlock
Hi
I have a similar problem with my Jiayu G3s (MTK6589T).
For most USB devices it does not react but i hope there is a chance to make it work.
I do not know if it si trustworthy but according to USB OTG Checker my device supports USB OTG.
When i insert one of my USB flash drives i can find sdcard1 folder (total commander) . It is empty but it reacts.
Can anybody please help or just explain what is the problem. Thank you

Hi there,
I think I have a possible solution for this case.
Many USB cables are not correct to link with computer. I have two cables, one of Jiayu and other (more thin) brought in a chinese store. The cable brought in chinese store don't work to link with computer.
I hope this information was useful.
Any updates?

This might help. Using an apk it is possible to make it work, IF kernel supports it. Don't know if phone has hardware support though...
I've read here that you should connect the ID pin to a pull-down 150k resistor, then to GND.

Test on another PC, and if that doesn't work - replace USB board - look for Keithross39's guide in General (search for 'replacing USB charger board'), has all the info you need to get this done yourself quickly/easily/cheaply (~US$10).

thanks for the reply sir... that's the only thing left out for me to do... to try my device to another desktop or loptop.. since i only have one desktop at home....
sir how can i tell whether my phone is a genuine one? can fake samsung devices be recognize by kies? on usb or wifi kies?
Verify that your phone is closed all applications (hold "home" key -
management activities - close applications) and move to the main screen.
Open the Samsung Kies program first and then connect the usb cable.
If the fault persists, uninstall the driver (Samsung Mobile Usb) from "Device Manager" on PC
and restart your computer.
Once you restart your PC, and open the Samsung Kies, plug the phone in order to re-install the
driver.
If still no go even restart the phone and try again
Try also another usb port and finally try another pc / laptop

Compare your phone to pics (Google search) of genuine devices, also Google & you'll find pics of fakes that you can also compare against (we've seen a few fakes on here over the past couple of yrs but not many, search for threads about this). Get an app like Android Hardware Info/similar (there are a number of similar apps on GP) which will give you the hardware details (CPU/GPU/etc) of your device & compare that to I9100 specs.
What makes you think it's fake ?
Cpu-z is a good app (free on google play) for see Android's details about hardware/software.
I've never heard of fake s2. It sounds so strange
Quiet, that you are neither the first nor the last to have problems with USB connectivity to PC. They are quite common problems.

coz there's a a lot of fake samsung products here in the Philippines... and by now it's really hard to identify which is original or fake.
those people who created those clone phones is getting better day by day. way cheaper but looks exactly the same.. i think they made
the hardware powered too, i've seen an s5 a clone one and it's rated by antutu with 30145 or something )
Don't forget to test different USB ports in your laptop or PC. Last resort could also be (if you're under windows, obviously) deleting the USB root controllers within the Control Panel > System > Device Admin and then reboot. In my experience, I don't need to reinstall Samsung's drivers and usualy recover the USB cable connection.

After installing ROM cant use external USB devices

I had Android 6 (Marshmallow) pre installed. With this version I was able to use external USB sticks and other devices (like a US Mause or a USB Keyboard). But after I flashed Eragon ROM the USB-C port no longer poweres external USB devices. Is there a hidden configuration I didndt notice? Or is this just my fault cause the cause is obvisios? Also Eragon Rom v3 is based on Android 6 so I through it would be passible.
Seems nobody knows why... Can somebody ask Skeleton1911 (I have ot enough posts to do so). Also What about additional driver installing for other USb devices (WLAN stick, Headset, )

Kindle Fire 2 CM 11-XXX USB OTG

Hi guys I am new here and new to this whole rooting, custom ROM thing. This all started from a need of an android device to run an app for a motorcycle efi tuner. It connects through a USB cable and allows me to change some tuning parameters in the module. I have never owned an android device, but I did own a Kindle Fire 2. After doing some research I stumbled across tutorials on how to install CM and make it an android device....and that where I am at now.
I have successfully rooted and installed CM 11-20160815-NIGHTLY-otter2, android 4.4.4, Kernal version 3.0.72+
Now the problem I am facing is the use of the usb cable to link the tablet and module. I have a USB OTG cable and after some research it looked like I needed a powered cable, so I made one of those too. I have installed Stickmount, USB OTG helper and USB OTG Checker. Running the checker I see that my device has the USB OTG API.
The interesting part now is when I connect the powered cable to the module and Kindle it will open the app automatically but it says not connected. The weird part is that it detects it enough to open up the app. Also I have not been able to mount through stickmount.
I am not a developer and not familiar with a lot of the lingo so at this point I am stuck. I don't know what else to try its over my head at this point. A google search turns up very little on this, although I have seen youtube movies of it working so I guess its possible.
Any help would be greatly appreciated!
Anybody have any ideas? I don't have enough post to put this in the kindle forums is it possible for someone to move it there?

Issues with connecting Redmi Note 4X to Windows 10

Hello. I'm a happy (?!) user of Win 10 Pro x64 since few days.
I want to connect my RN4X Snapdragon to PC, using usb on my pc's motherboard.
However, despite setting option, that I'll listed below, my phone is still not recognisable as useful stuff.
Without changing anything on my phone since my last flashing topics (Feb and March this year), I was fully able to connect easily to pc with win7 x64. I also was able to connect (using Xiaomi's cable, cheap replacement does not seem to work) phone to win 8.1 x64, where only the basic adb fastboot were installed. But, I cannot do the same on newest Windows.
I've done:
1. Installing minimal adb and fastboot 1.4.3. for all users (I'm the only one account here, but not sure if that's matter)
2. Having programming option enabled, usb debugging enabled and all that good stuff.
3. All four elements on that list - https://************/how-to-fix-mtp-devices-not-connecting-on-windows-10/
4. I've tried to install it as adb interface, installing it manually, installing it by using *.cat files from xiaomi_usb_driver archive, that contain that kind of stuff for newer windowses (it's from this side, if I remember it right - https://www.xiaomiusbdrivers.com/2018/02/download-xiaomi-usb-driver-2018-for_4.html)
5. Almost all stuf from here - https://www.jihosoft.com/android-tips/windows-10-cannot-recognize-android.html. Because I do not have Samsung, Odin mode is not an issue
6. I've tried to install my Redmi 4X as MTP device. However, my phone during each connection to PC started himself in charging mode (I can change it). Even changing it doesn't changing anything, though.
7. Editing the bulid.prop, adding there few lines describing how the phone should behave. I've saved it, but my original version of bulid.prop does not have anything in there about types of connection. I don't remember it word by word, but I've could check in history if anyone will find it interesting.
Drivers for usb 3.1 are pre-installed with mine version of win10 (I cannot install drivers given on my motherboard's dvd attached, system says that I'm currently having them).
When I try to install it manually via device manager, on the first time it says, that is other device, identifed briefly as MTP. However, installing it either as Android ADB interface, fastboot interface or third option does not give me anything. What's worse, even when I've pick windows/INF as my source of drivers for this device, it does not list on "lemme pick ddevice type" MTP type devices. I'm using win 10 in polish, so it might be that I'm blind or does NOT understand translate.
What else could I do? I can of course use wife's laptop with 8.1, usb sticks or other stuff, but I would like to have it sorted out.

Not sure. How to check it? We use to have 16GB OTG to USB2.0 (other end was micro usb B), but we must have put it somewhere during moving out to new flat, cause I cannot find it now.
gonna bump it, cause there's not any clue yet.
Same here.
