[Q] Does anyone use in-car USB? - myTouch 4G Q&A, Help & Troubleshooting

I just upgraded to this phone from an LG Optimus. Got er all rooted with true s-off thx to the guide on this forum.
My car, a 2010 Kia Optima, has a USB port in the factory radio to browse and play mp3 directly off USB mass storage devices. This worked perfectly with the old phone. The notification on the phone would come up just like PC connect to enable mass storage then stereo could see sdcard etc. With this phone, all I'm getting is charging regardless of the PC connect settings.
Old phone running cm7. New phone Sense 3.5 Mikrunny. I did try my wife's phone which is stock Gingerbread and no joy also. I know it's probably the way HTC does their drivers but was wondering if someone here has accomplished the same thing in their car and might have some insight. Thanks for reading.

Just happened to check it today. It won't work, because USB device enumerates as composite device with one of the functions being mass storage, rather than just mass storage device. Your car system USB host isn't advanced enough to recognize mass storage behind composite device, it seems.

It worked fine on my after market had unit... I just changed the mounting, not sure about on a kia though

I have a 2011 Chevrolet Cruze which also has a usb slot to play music and it runs flawlessly on my myTouch 4G running miui. I guess it might have something to do with your partition type.

Since car systems don't have any standard for USB host firmware, and each write their own, the support level will vary widely between different systems. Some will support composite devices with mass storage, some will only support simple mass storage devices. Some will support FAT32, some older might only support FAT16. etc etc. ROMs shouldn't have any impact on it, because they mount the SD card externally in the same way.

I know it's not a perfect solution, but I use one of these.

USB Mount

Not sure what fixed it, but the CM on G1 allowed me to mount my SD using my car stereo's USB (JVC KW-AVX820). Native G1 and none of the 3 USB modes on the Vibrant work. Any idea what file system feature did that?
Reuven
Same here. My Genesis Coupe keeps showing either 'Media Connection Error' or 'No Media Connected'. It even rebooted my nav/stereo this morning and then froze it on the FM screen with no audio. Had to turn the car off, then back on for it to be fine. Not sure why the Vibrant would have issues like that.
Actually, with my G1, I hadn't got USB Mount notifications for awhile. Other rom's however worked fine. My wife's MyTouch works no problem, so I know it shouldn't be the car.
I don't know anything about car computer usb, but I'll share one experience I had working with a copier at work: USB running in a mode that simulates a USB thumb drive works. USB running in a mode that shows a micro SD card READER (as opposed to a single solid-state unremoveable drive) does not. That discrepancy could be responsible for what you are experiencing.
Make sure after you select mass storage you then mount the usb (its a two step process)
But also, it still might fail as I've noticed when you do this the device is actually mounted as well (oh that glorious 16gb of onboard space!) so the stereo might not have any idea of where it should be looking.
You need to go into settings and enable USB debugging
I think it's under settings application development
that didn't do it
Try disabling USB tethering

Generic USB

Is it possible to develop a compatible generic USB driver for our beloved SSGS? It would be cool to just plug in your SSGS to any PC or car stereo and get recognized without downloading the driver first. SSGS is incompatible with everything...
mass storage doesn't work for you?
Yeah was gonna say that too....
The only time I've loaded drivers was to use odin other than that I've just plugged it in??
It does'nt work with car stereo ;(
Most MP3 audio system thingy uses generic driver so... it doesn't work. Sorry, I guess it works on other PCs with the mass storage switched on but not the car radio systems or similar systems. I have a Honda Jazz/Fit - debug mode, mass storage, media player mode... don't work. It says "unsupport".
Moto Milestone is compatible with most MP3 audio system. Is there a way to extract that driver?
I'm pretty sure that is not a driver problem but something that relates to the USB-Controller in the SGS. It is a different one than the one in the Milestone/Droid and thus the driver's won't work. It also means that a "native" mass storage mode is most likely impossible
I do think the mass storage on sgs is generic mass storage like every commercial USB drive. None of my Windows machine requires special drivers to mount the partitions on PC.
Anyway, drivers are supposedly to be loaded on host, not the phone. Even if you wrote a driver which works, you will have to find ways to load into your audio system, which is likely not possible.
P.s. Upon selecting mass storage when prompted, did you pull down the notification bar and click on mount? Otherwise it would be just an unloaded drive to the host.

Cannot connevt to any media device via usb

Hello..i find it impossible to connect/mount my galaxy s as removable device to any of my dvd players,car ,stereos as removable device..it works on pc..i do not understand why..my desire,desire z, couldd be mounted and read just fine on all of those devices..i have on usb settings set for mass storage instead of kies and tried with debugging both on/off..no idea why..very very frustrated...this could be reason enough for me to give up the device.i use this feature alot..

Is there any way to ONLY mount the external SD card when mounting as mass storage?That would solve all of my problems..
Well, I think no known solution till date. A composite usb device, not plain mass stroage device!
Well maybe this can help to solve this, once i conected it to my car stereo, i was triying to conect it when i got an error end process of the usb conector it got stick on the display bar and when i reconected it worked, i never could make it again..... But ís posible i did it....

Connecting to MAC via USB ???

Well it's official, I'm at my wits end trying to figure out just how to connect my Note 10.1 to my Macbook Air connecting via USB cable. Every time I connect the two, I can't find it ANYWHERE on my laptop !!!
Anyone else experience this all too frustrating conundrum???

Android file transfert works fine. Do NOT install the Samsung USB driver from kies this Is complete ****. airdroid is **** too you can't even copy a folder. ah don't forget to disable USB debbug otherwise aft won't detect your device.
I've never been able to see any of my Android devices on my Mac without using Android File Transfer & I believev that's the way things just are.
The problem is that Android only presents itself over USB as either a media device using MTP (Media Transfer Protocol) or PTP (PrinterTransfer Protocol) standards - settable in settings. It does not support USB Mass Storage protocol.
Windows supports MTP out of the box for Media Player, so when you connect your Android to it - it shows up as what looks like, for all intents and purposes, a hard drive. In the Note's case - you get two: one for the internal simulated 'SD' card - and one for the actual SD card reader. This is why when you copy files to and from the Note, the experience is a little weird - it will offer to convert files for you, for example.
Unfortunately, MacOS X doesn't support MTP because, I suspect, Apple wants everyone using iDevices and their proprietary iTunes protocols which aren't compabtible with MTP.
Now, while it's dumb of Google not to support USB Mass Storage in Android, it's equally dumb of Apple not to support MTP in their OS.
Fortunately, there are addons you can get to fix this (as noted above).
Windows users (and I suspect, Linux ones as well) don't have a problem.

It's not across the board android, just the tablets. All my phones up to the note 2 would connect as mass storage even with exchange installed. Even the og note
I've just found an app called ES file explorer. Set up your Mac as a smb server and you can access your files via wifi. Much faster than blue tooth.
A video file transfer from my macbook to my note 10.1 took 4 hours, similar file via wifi took about 5 mins.
Still testing the app, but quite pleased so far.

Kinda. I don't think my Galaxy Nexus phone shows up in MacOS either (it's been a while since I checked so I could be wrong).
To complicate matters, each vendor adds bits to the OS. For example, Asus Transformer Primes can read NTFS drives out of the box - but most Androids can't. They've added something to the kernel to add the capability.
AFAIK, the base Android doesn't support USB Mass Storage on the host port.
Did u try to mount the drives in recovery? I'm assuming your rooted

Music in car through usb

Does anyone know how I would be able to play music in my car through usb? I am currently using tune link which uses Bluetooth and 3.5 jack. The issue I have, is that I have to change the song using my phone rather than the control buttons on my steering wheel. Sounds dumb, but I hate having to pick up my phone and navigate to screen to change the song.

Try using an OTG, it enables the phone to be used as a typical computer usb port.
I will try that.

Have 100% the same problem. Did anybody find the solution? My old Xperia Acr connected like a common flash card and worked fine. Now I have to use AUX and this is not so comfortable =/
Why do you use a cable AND Bluetooth ? Does you car have AD2P ? If it has you should be able to play music through your phones BT and have the steerring controls . I have a Kenwood head unit DNX 9140 and when i pair my phone to it, i can play music and still keep steering controls over BT
The music out via USB was removed on the s5...was present on the s4.

Not true. There is a lot of misinformation promulgated on the subject. Music out on USB works fine on my S5 just as it did on the S4, S3, S2 and S1..
But that isn't to say that Samsung, Google or (especially) the automotive audio equipment cartel make much effort towards standardized interoperability. It's frankly a mess, a hodge podge of half ass implementations and proprietary protocols that usually don't play nicely together. It can be made to work with carefully chosen components or creative approaches. But randomly connecting components from two different vendors typically fails.
While Samsung and Google could be characterized as only having made a minimal effort to provide standardized USB support.. that is still leagues ahead of what most automotive audio vendors have done. Not to mention that it's routine to find inaccurate details, if not outright lies of what automotive component X will supposedly interconnect with. I sometimes wonder if their marketing departments even bother to collate real facts on the subject before they write their copy.
It's not too hard to find decent DACs and headphone amps that will accept USB audio out from the S5, but I frankly gave up trying to figure out what would or wouldn't work on the automotive end. I ended up going with a brute force approach and installed a SBC (miniature PC) in my car. Having a full PC as a middleman, means that there is a vast array of powerful software (and hardware) that can slice, dice and format the control stream to whatever is needed by the auto head unit. But it's hardly a simple or off the shelf solution.
The OP can probably find a working solution if he searches hard enough. The S5 has USB audio out, although making it work with some car decks requires a combination of root, custom kernels (proper USB host support) and audio apps. An app like USB Audio Player, in conjunction with a kernel that has proper USB host support will satisfy many auto decks.
Hopefully Android L will give us better USB support. But it also depends on how sane your automotive equipment vendor was when they designed your car deck too.

The problem is that since 4.1.2,USB Mass Storage was removed.
Most, if not all, radios, media players, etc don't support the MTP protocol. They require a mass storage device, and do not support a media device.

MTP is a newer and much more capable protocol. The problem in your example is that radio, etc vendors are stuck in the past and not adopting newer standards.
MSC (mass storage) has many serious drawbacks that are overcome by the newer transactional protocol. MTP was standardized six years ago, which is just short of forever in consumer electronics. So one has to wonder why the radio vendors continue to drag their heels and can't get with the program.
It's like blaming Android for having moved to flash memory.. and refusing to go along. Expecting everyone to continue using cassette tapes instead. Yes that would be one way to maintain compatibity. But it doesn't make a lot of objective sense.

Yes, and for activation Mass Storage root is required ...
Guys, but what about using USB analog audio input? I remember I did something like that with Galaxy S II - from 5 mini USB pins one was used to sense what phone is connecting to - for ex if it is a car dock, desk dock or... should it enable analog audio output on USB data pins.
Unfortunately I no longer have dock I made back then, anyone knows if that might work with S5?

EDIT2: Oh it seems I completely missed the point, you want to use it as mass storage to connect to car USB port.
