Hi all,
Since i updated my Note 10.1 tablet ( ed.2014 ) to android L, my external dac stopped working.
The usb dac is the Dragonfly 1.2 (Audioquest) and worked fine before, plug & play.
I tested the dac, the usb-otg cable and also the usb connection of the tablet => they are OK.
Hardware hasn't changed, so to me, it looks like a software problem.
Is the usb power output (more) limited ?
I used the "usb host diagnostics" app that tells me the dac is still recognised.
Is there a way to make the dac function again, or do i have to go back to the earlier version of android ?
thanks !
Jo

good day to everyone. firstly, i would like to thank you for having the time to read my post.
well basically heres my inquiry, my unit is the alcatel tab t10. i never had any problems with it until recently, my device's usb port suddenly stops working.
tried unchecking the usb debug mode, tried checking it but to no avail, the usb still does not work. it doesnt seem to connect to my laptop. tried changing the cable.
i also tried connecting my device to my brothers laptop.
correct me if im wrong, but when the usb fails to connect to any laptop, their should be a notification in the laptop that the device is not recognized. but in my condition, no notification shows up. its like my device does not really connect at all.
oh and if it helps, i bought an otg cable before it started malfunctioning. but the only thing i had conneceted to my device is a wired mouse and a wired generic gamepad, which both seems to be working perfectly fine.
also, if i connect my device to a wired mouse, it would work perfecly fine. i could also connect to a usb flash drive, that is via the otg cable.
so whats weird is that the usb cable does not work, but the otg cable works fine.
if you have any question or any suggestion , i would truly appreciate it.
Hmm.....well the good thing is the port itself isn't "dead" as you can still utilize it for OTG. My only suggestion is make a backup of all your apps and data and try a factory reset.

thank you for the suggestion guitarman2010. unfortunately my usb port isnt still working. i also reflashed my device's current firware. but still wasnt the solution i was looking for. i was just wondering if there is a directory under the root folder that holds the devices usb driver? would it be possible that the device's driver itself got deleted? i wam still at awe that the otg cable still works like a charm.
and another thing, is the male usb pin the same with the flash drive's pin? cause if i connect the usb cable to the otg cable it wont work, but the flash drive works normally.
sorry for the amount of question im posting
thank you very much for the suggestion. especially when u told me that the port itself wsnt dead. i can now breathe easier..
and future suggestion and advice would be appreciated.
do you guys know how to access the phoneutil in tablet? maybe i should change the usb option to pda? but i heard that its only applicable to samsung 4.0.3 devices? suggestions are appreciated.
Hello everyone.
First of all, since I'm new here, please forgive me if these are repeated questions.
1. Is there ink effect for latest release of android revolution rom ?
2. What is the best kernel that improve quality of sound ?
3. Any chance that I can run portable Hard Drive ?
Thanks for your kind help.
Regards,
For question 3 , no you can't run a usb hdd unless it is externally powered...
Though I believe it may be possible with the right OTG adaptor.
I believe this because I have a tv tuner that was working but the OTG adaptor is iffy, and after a short while I got the dreaded "High powered usb device detected". Might need to experiment with OTG adaptors...
Hi,
I have been trying to integrate usb webcam to my sony experia t3 phone through OTG cable since few days.I tried many apps which is available on play store for this purpose and none of the app worked. Except for two apps ,it showed "unknown device connected". OTG cable works fine if i connect to a pendrive ,but webcam doesn't work. And I am not able to get this information about my webcam whether it is a UVC supported one or not. So can anyone please resolve this issue.
PS:My phone is not rooted and android 4.4
Hi guys, should have my P8max tomorrow, was just wondering if any of you guys had tested USB OTG with it? If it can't do USB audio out then that's going to be a major problem for me (if it doesn't support it natively that's OK, providing an app like USB Audio Player PRO or Hiby Music Player works). Generally anything that has OTG support will work with those apps, so should be fine, but always nice to have confirmation - don't suppose anyone here has tested it out? Any other feedback about USB OTG welcome.
i tested internet via usb otg. It's not working bec. google has disabled usb otg on android 4.4 and higher. why? i don't know. it's stupid google decision.
internet via usb can be enabled but:
1. it's need root
2. it's always need wifi or fake wifi connection
3. stupid google
USB OTG drives work for me, the DACs I have also work, although they need USB Audio Player PRO or Hiby Music to function. Only phone I've tried with functional USB ethernet via OTG was the ASUS Padfone Infinity, and even there I suspect it only worked because the drivers were intended for use in tablet mode.

Confirmed ... USB OTG works for my P8 max...
Confirm Usb OTG working on DEV701-L europe.
I have connected a 1 Tb 2,5" external Hd and it worked perfectly.
I posted this over in the Edge forum yesterday but thought it might get more views here:
How can one enable USB audio on the Galaxy S6? I have the Edge model from AT&T, though I'm sure that makes no difference.
I have a USB DAC I would like to use the phone with. I have a USB OTG cable, and should be able to connect my phone to the DAC to send digital audio from the phone to the USB. This has worked fine on previous phones, and has been supported as a native feature of Android since 4.0.
On my Galaxy S6 Edge, it just doesn't work. It must be missing something simple. In developer options, 'Prevent USB audio routing' is set to 'Off.'
Has anyone had success doing this?
i send my s6 back to samsung for fixing a loosse home button. But i have a OTG cable and attached my USB headset on it without tweaking anything. It was just plugging it in and audio worked fine.
