If the hubs are powerd then it's sure work , but the hubs above is unpowerd but also work ? so what's the hub do to make the ud110 work ?

"The SA9027 [USB receiver of the Stoner Acoustics UD110] is a high performance up to 32bit USB Full-Speed compliant audio steaming."

Theoretically, a USB 2.0 hub has a transaction translator (TT).
The transaction translator should convert the USB 1.1 full-speed traffic only supported by the UD110 to the USB 2.0 high-speed traffic also supported by the Galaxy S4.

USB 2.0 / USB 1.1 Galaxy S4 <=> USB 1.1 full-speed <=> USB 1.1 UD110
USB 2.0 / USB 1.1 Galaxy S4 <=> USB 2.0 high-speed <=> USB hub TT <=> USB 1.1 full-speed <=> USB 1.1 UD110
 
Apparently, the USB 1.1 full-speed dialog between the S4 and the UD110 has some issue.
Using the USB hub introduces a USB 2.0 high-speed dialog which gets around the issue.

DanBa, just to exclude all other possible causes - are we sure it's not a power issue here? Remember, I was reporting about an issue with Xperia Sola and RSA Predator, where an introduction of non-powered usb hub solved the compatibility issue just because the hub was reporting to the host as needing 0 mA (no power draw), whereas the Predator was claiming the whole 500mA, merely needing 50?
 
Just checking...

Unlike the Xperia Sola, the Galaxy S4 can directly work with the FiiO E17, i.e. 500 mA-required USB DAC.
The FiiO E17 requires 500 mA; and a USB peripheral like a USB DAC may draw a maximum of 5 unit loads (i.e. 500 mA) from a port in USB 2.0.

MaxPower:             0xFA (500 mA)
 
But I am not sure of anything without analysing some dmesg log output and USB descriptors of the Stoner Acoustics UD110.

DanBa:

Awhile ago, you mentioned using a Qi charger.  Have you tried this in tandem with an external DAC and, if so, can you actually charge your S3 while listening to music through the micro-USB port?

 

[DanBa]

Sorry, I don’t have yet a Qi wireless charging for my new Galaxy Note 3, because the Note 3 S-View wireless charging cover is not yet available in France.
I think wireless charging the smartphone while streaming music through its micro USB port won’t have any problem.

"CarPad is Qi functional and works well with the Nexus 4. Tested both with TPU case, Diztronic Matte Black Case, Official Bumper, and bare-back. The average charge on an idle phone is around +600mA and with load of Spotify streaming music, Android GPS navigation, BlueTooth connected to head-unit, and screen on at lowest brightness, the charger gets nearly +100-200mA".

What do you think about pipo m9 + dac port lx + o2 (you can prefer amp) + Anker astro e5 or Tera for sq with iem.

So before I purchase a fiio e07k I just want to make sure that my samsung galaxy s3 can host its DAC function

Any confirmation if the HTC One mini will work any of the dac/amp? Can't find it on DanBa's latest updated list. Looking to pair with an Apex Glacier

Hi,
 
I just connected samsung galaxy s 3 via usb otg to fiio e07k and it works fine. I reconnected it many times and it works all the time.
 
My sgs 3 is with siyah kernel, android 4.1.2., I'm from Poland so I quess it's interantional or european version of sgs 3.
 
I'm not sure if I can hear any SQ improvement with my akg k404.

Very tricky with the fitting of USB plugs.

Sorry guys, would need help to know if the LG G2 works with digital out via otg, hoping to pair with a Glacier. Am moving from iphone 5 to android, so trying to decide and figure out which phone would work with the Glacier

Hey guys,
Wondering if some can answer this for me. i've searched but couldn't find the answer.
i have a stock Sprint Galaxy S3. i also have a subscription to google play music all access.
Can i use an external DAC specifically for this app?
