[Q] Won't mount drive without debugging on

Since I rooted, using unleash the beast and now have one click lag fix, when I connect my usb cable to my phone I can click on usb mount but nothing happens unless I unplug.....turn on debugging and reconnect. Now Win 7 makes an audible sound when I plug in....I click on mount and both my internal and external sd card show up......what's up with that? Thanks in advance.

Try changing the usb mode to kies(sp?) Then plug it in and it soul ask if you want to mount it

Small issue: USB storage by default on USB plug while USB debugging is on.

Hi guys,
I just got one problem which I didn't have in the past, during my last 50 flashes
When I have USB debugging on and I plug in the USB it activates the USB storage by default.
I checked if by any chance in the USB settings Mass Storage is not ticked and it wasn't. I know it has no connection with USB debugging but it worth a try.
Is there a way to fix this?
Im running JPM + OCLF (it was doing the same before lagfix)
Before, I am 100% sure it didn't happen. Still cant understand what caused this behavior.
Thanks a lot!

no one??
Hm.. I knew it was special.

Nope, it's doing it to me also.
Immensely annoying because I'm using an old HTC charger with a mini->micro USB adapter, and whenever I plug it in the phone thinks I've connected a USB cable and enters USB debugging mode. This bug then kills whatever music I'm listening to at the time by mounting the SD cards as USB drives, which I can only restart by disabling USB Mass Storage, waiting for the media scanner to finish and then re-opening the media player!
Anyone else seen or found a way around this?

[Q] USB Audio (car usb connector)

I've been searching for a while to solve this.
I'd like to connect my HTC one to my car usb connector.
I've seen several repoirts claiming usb audio works, connecting dac's etcetra.
I know I can connect usb drives with a micro-usb to usb connector, tried it and this works.
But I have also seen people saying you need an USB OTG cable for this, so what is it?
I've already connected my One via the micros-usb to usb cable to my car but I do net get audio via the usb on my car equipment.
So again the question, is audio out available on the htc one (and on other android phones) with the stock rom.
Some of the report where talking about CM roms, I do use the elegancia one but I have no intent of switching to CM.

since the HTC One does not automaticly plug as mass storage i guess that the car radio simply does not recognize the phone as a mass storage with music.. an USB OTG cable would "fix" it since it will force the phone to be shown as mass storage.. (its a guessing anyway)

And you have guessed correctly. The USB otg cable works fine.....except it added ringtones et al when you select root folder. Worked ok if I navigated to the music folder (assuming your vehicle has that option).

Well, for me it does not work.
As I said before I can attach a USB drive to my phone and I can accomplish this by using a micro-usb to usb adapter.
When attaching the drive my phone complains it cannot charge and that I need the standard charger.
But when using a file explorer I can see (read and write) the contents of my usb drive in the storage/usb folder.
I thought this was enough to decide that the converter was OTG but now I'm not so certain about this anymore.
Is every usb to micro usb an OTG or what are the extra requirements?
Anyway I tried again to connect to my car audio and the message I got on the car was
that he could not charge the phone but the phone was as well not recognized as media input.
Because OTG adapters are very cheap I ordered one which explicitly says it is OTG,
I'll see what happens when I can try that one out but in the meantime all comments are welcome.

Yes, the cable I had explicitly said "OTG".
I only experimented with this for fun, my Elantra also supports built in bluetooth (phone controls are on the steering wheel, mic in the roof) so I mainly put my One in my car kit, launch car mode and away I go.
The OTG cable worked well for me when I tried it though. It did NOT work with my Son's Nexus 4 so these things can be finicky.

[Q] how to connect usb hdd 500gb to z1

hi i have external sata hdd i want to connect this to my z1 is it possible if yes please tell me how can i do this ?

Do you have a SATA HDD or an HDD with an eSATA Port?
If you have a SATA HDD you could try using an external USB Case and connect it over USB-OTG. If you have the latter it won't work without additional hardware (e.g. a Notebook with eSATA Port)

i have sata hdd with external usb case which i try to connect with my data cable but nothing happen any suggestions or any way to do that ?

It should work...
One questions first:
What Filesystem is present on that HDD? Preferable would be ExFAT. NTFS _could_ work, but i don't know that for sure.
Second:
After you've connected the HDD to your device via USB-OTG cable you should go to Settings --> Storage. Down at the bottom should be a point wich let's you mount your external USB device. After that, it should be available for r/w.

actually i tried with our data cable which we use for connect mobile to lappy not usb otg if it must usb otg i will buy new and try :good:

how'd you manage to do that? should'nt be possible through different genders on the connectors...
The only way i can imagine to connect those two devices without messing with the connector is a NAS-Storage. Those are Harddisks available from IP Networks (e.g. Western Digital MyBook).
Those devices have the proper port to connect your smartphone with itself. Well atleast physically.
Those ports on NASes are for output only (mainly). You can connect a printer to make the printer capable of networking. But connecting a smartphone on that port won't work since it isn't designed for such things. All you could do is mount your internal Storage as Mass Storage over USB (not MTP) and use your smartphone as network share. But browsing through the files on the HDD will still not work because of a lack of connection between the real harddisk and the usb port.

You must also connect an external.power source, the USB otg doesn't give enough cureemt to power ir up.

how to do that any idea ? please help

There are splitted USB cables one you can connect to power line like a computer or adaquate USB charger andthe other to the phone...

Free option is flashing doom kernel with boosted power output of the USB port. That COULD work, but it doesn't have to. Make sure you're using passive USB connectors that you're using. Ergo - it's just a regular USB cable and no additional software needs to be installed.
Try the USB otg helper from Google play too. It might also fix it.

Anyway to play music thru usb port on car radio?

I'm wondering if it's possible to play music on a car radio (or any usb input) thru the usb port on the note 4?
Any app, mod, hack, tweak to mount a certain folder (music) as a thumb drive?
I have several usb input audio devices, but I can't access anything when I attach the note.

I feel you, I tried to do the same with no success ended up buying a 3.5mm headphone jack to rca for my car stereo ?

Yeah that sucks

So you're trying to MOUNT a USB DRIVE filled with music and play it to your car stereo? You using a 3.5mm cable or Bluetooth here?
I have some USB OTG cables (really cheap, ebay) and play the music from my SD card using PowerAmp (FLAC Playback, also allows folder choosing; your USB drive?) through the OTG cable, to my Fiio E07k, then to my headphones/speakers. Works FLAWLESSLY, and if I plug anything to the headphone jack simultaneously, it will re-route the audio.
Hope this helps.

I want to use a usb cable from my phone into my car radio usb port and play the music that is in my phone thru the car radio using the usb cable and not the 3.5mm head phone jack.

i believe this is a feature in lollipop to enable audio through usb. gonna have to wait
"Android 5.0 has added official support for USB audio devices (both input and output) along with lower-latency audio input and the ability to mix up to eight audio channels. All of which means one, amazing, thing: "

I want my phone to act like a usb thumb drive when I connect it to my car radio thru the usb port.

I can't remember, I set it up a long time ago. It's a 64gb uhs1 card. I remember I had to format it with a pc app to get it to be recognized in my (then) Galaxy S3, and I simply moved it in to my note 4.

OK, with that being said, what stereo you using? Display style or single din?
Is it linix based or android?
Brand and model number?

I've got a pioneer single din in the wife's car (can't remember the #) and I've got a Kenwood dnx5120 double din, which has a usb port that will read a usb thumb drive or a hdd (or iPod / iPhone) but will not "see" my phone when connected usb.
I figure if it can read a usb thumb drive or even a hdd, why can't the note 4 mount itself as a thumb drive (external sd card) and allow my radio to read it's content and play it's mp3's?

Ever found a way?
Im in the same situation.
Ive tried the apps that enable usb mass storage mode on my sgh-1337m galaxy s4 and while it works and my computer recognizes my sd card as an usb drive, my car stereo still does not.
Any other way or USM enabler that works?

I have never found a way ? sad to say. If anyone can point us in the right direction if that direction even exists, that would be great.

I just bought a Kenwood KDC x701 and I had a very unusual set of circumstances. When I plug in my HTC 10 to either USB cable one or two nothing happens other than charging the phone. The Kenwood radio does not recognize the HTC 10 at all. I thought this was completely normal as I was not trying to mount the HTC 10 internal storage to play music files as I have no music files on my phone except audio recordings I make myself a phone calls and such. I am able to stream music via Bluetooth from the phone to the radio just fine and that's what I've been doing this entire time. The only thing I listen to is tidal music streaming service. So the other day I went to plug in my lgv10 to charge while I was driving and a funny thing happened. The radio display indicated it was reading and then went into a hand mode, it is literally called hand mode LOL. The next thing that happened was a message popped up on my phone asking me if I wanted to download a Kenwood app from the Play Store I hit cancel. Then all of the sudden it started playing music from the Tidal music streaming app. Although no information was displayed on the radio I was able to use the buttons to skip forward and Skip ahead of the different tracks but I am not sure I am able to pause or play music on the radio controls. I am not sure how it is possible to stream digital audio through the USB cable directly into the radio. I have no audio files stored on my phone on either phone and I'm not even sure how to mount internal or external storage on the phone if I wanted to use the head unit to access any audio files. So I called Kenwood and they said what I described is not possible with any of their head units. They did say that I should be able to mount my internal or external storage on my phone and use the Kenwood app two act as a music player and play the files on the phone and have them information sent to the radio. What it sounds to me like is I have a USB OTG situation with the LG V10 and no one knows why. Also of note I am unable to stream music from the lgv10 to the Kenwood stereo and no one knows why Kenwood does not know why. All of the track information is displayed on the radio I can control the songs going backwards and forwards the timer countdown xcetera but there's just no music. I will say streaming music from Tidal music service streaming app sounds much much better through the USB cable versus Bluetooth. I can't believe how much better it sounds over the USB cable it's like adding an amplifier to your system. I will try to make some videos and if this helps anyone that's going to be awesome. Also of note when I select source to USB when I have my lgv10 plugged in it calls the source Android1. This totally sounds to me like USB OTG. What do you all think and has anything like this happened to anyone else? And this does not work with my HTC 10.

I don't believe that this is possible any longer. It was possible under older versions of android (pre kit kat i believe) where the "internal sd" was seen as a physically separate storage device instead of being mounted under /data/media. Once they made this change, they had to swap from USB Mass Storage mode to the annoying Media Transfer Protocol. The reason Mass Storage had to be dropped is because of how it functioned. When you allowed access to your "internal sd" it would have to dismount it from the OS to give the host device plugged into the USB port exclusive access to the file system. Since they made the move to mounting it as /data/media there is no way to give that exclusive access any longer. Trying to dismount that /data/media to give that exclusive control would yank away all of the writable media away from the OS. Android would likely crash, or at least nothing would function any longer.
