I tried on incredible forum and got someone asking if I've tried the obvious. PPCgeeks hasn't had any replies yet, and google searches only return me to my own threads! So....I'm trying my luck with you guys.
I've got an incredible, and was running the stock 2.1, rooted, and I had the phone set to automount the storage as a disk drive whenever connected to USB. Due to a bug in 2.1, whenever you set it up to mount automatically like this, ONLY the SD card was seen as a drive, and the phone storage portion was not available. You could make them both available, but not automatically.
This was PERFECT for me, because I have a car stereo that accepts USB disk drives, and all my music was on the SD card. The one limitation of the stereo is that it only reads the first available partition. Nothing I can do to change it. So, with that setup, it mounted only the SD, the stereo saw only the SD, and I was in music heaven.
So I got virtuous 3.01 loaded on there, and I love froyo.....except....they fixed the mounting bug, and now the phone properly presents BOTH the SD card and "phone storage" when it's plugged into USB. And of course, phone storage is the first presented partition. End result is my car stereo now CANNOT see ANY music stored on the phone. Worse yet, since it takes the phone some time to do this, the stereo doesn't always recognize that a usb drive is even plugged in, where the timing was absolutely perfect before and it picked it up every time.
This seems like it should be extremely simple, like there should be some setting in the phone to mount only one single partition when plugged into a usb port. But for some reason, after days of searching, I can't find this anywhere - everyone always has the opposite problem and wants to make it mount everything.
Can someone please point me in the direction of a setting (most preferable - since I know it worked under 2.1, I know the phone must be capable of this at the OS layer), an app, or SOMETHING, that just straight up automounts ONLY the SD card when plugged into USB?
Under 2.1, with the "bug", it worked FLAWLESSLY. Every time I got into the car, plugged it in, and bang, music. I don't wanna give up froyo because of this, but it's pretty frustrating. I hope maybe someone can show me what I've missed!

Hopefully someone can help... When I plug my Evo into my (off brand) car charger, it makes the SD Card unavailable (like it was plugged into a PC). At first, I thought it might be the charger, but my wife's EVO works fine. Any ideas???
Here are the things I have tried...
- Restarted the phone
- Moved all apps back from SD card to phone memory
- Disabled USB debugging
- Restarted phone again
Update...
When I unmount my SD card, plug in the charger, and then re-mount the card, it works. Pain in the rump though... and in case anyone was wondering, no my phone is not rooted or modified in any way. My wife's EVO works fine with the same charger.
Anyone have any ideas??? I would really like to be able to access my music while the charger is plugged in without having to unmount/re-mount.
Go into settings and change the default USB Connection action from USB Mass Storage to Charging. You must've changed that a while ago and forgotten about it.
Are you using DoubleTwist? It has a feature that automatically mounts the SD card to be used from a PC over the USB cable. For some reason it thinks a car charger is a PC.
This probably holds true for other programs that can auto mount SD to USB.

Already thought of that... That wasn't it. Thanks for the help though.

DoubleTwist was it! I went into the settings and disabled that option. Thank you! This is why I love forums!
THANK YOU!
The same issue was driving me nuts.
DoubleTwist is great; but the xda forum is even better ...
I have a weird problem, When I plug my phone into charge, be it via PC or even the wall connection, it acts like "disk drive" mode is set, even though charge only is set.
If I reset it to charge only it then says "preparing SD Card" and is fine again.
I know of one other person with the same problem, any fixes?
I have this problem when i use my HTC cable but nt while i use my Dodgy cable from hong kong,
work around : Change the mode to HTC Sync from Charge only and it charges perfectly fine...
You can reselect charge only mode and it works fine, just dont understand why it acts like a disk drive in the first place
quite wierd i agree, the hong kong cable working, makes me think its the cable, but why could a cable change it to disk drive mode automatically(i have seen my htc cable change it to car mode automatically, which is understandable)
Do you have any apps such as Double twist, winamp etc? These apps have an auto mount sd function that you need to disable. Then magically it will no longer do this.
Check your apps people.

WINAMP!
thank you, I didnt realise it had an automount function.
I knew someone on here would know!
BOOM. This place has the answer to almost everything Android.

same here!!! it's since i permarooted with visionary_r12 and flashed hboot as well as an oc'd zimage and the adb-boot.img (before kernel)!
the strange thing is: even after a wipe and a clean flash of a stock rom i now have this problem...
must have something to to either with visionary, hboot or boot.img i think!
EDIT: shame on me, and big thx to ephumuris! indeed winamp was the cause... the strange thing is: i installed winamp about two weeks or so, and the automount started when i flashed hboot etc. ok, perhaps it has something to do with root rights etc.: winamp automount was active since i installed it, but started working after permaroot! anyway, big thx again!
A friend of mine also tried plugging in his HTC G2 (with Cyanogenmod), which also did not work. And I've been looking for a solution all around the place, and it seems to be a problem with Android phones in general; however, I know it's possible to get it working somehow because not everyone has the issue.
Basically, no matter if I have the USB connected via charge only or mass storage, the car display flashes "UNSUPPORTED". I've tried it with and without USB debugging enabled. And with all those combinations, I've tried having a music application open/no music apps running.
I also tried a solution here, which also did not do anything different.
I've also seen a few responses saying to just use Bluetooth instead. My car does not have Bluetooth capabilities. Using an AUX cable is a possibility, though I'd rather have the USB working.
Thanks!
Seems like the system wants to recognize your phone, but USB mode takes a few seconds to enable and therefore the system just rejects it. Disk mode will DEFINITELY have to be activated at some point, but the question is when. Try these steps:
1. With the car on, turn on the radio but don't have it in USB mode yet. Use radio, aux, cd, whatever. This will likely power the USB port at least.
2. Plug in your phone, make sure to select disk/mass storage mode.
3. Wait like 10-15 seconds for it to settle in, THEN select USB mode.
If that doesn't work, try different combinations. Like start with the radio completely off or something. If you have more than one USB port, try a different one. Other than that... I'm stumped. I got it working in a rental Ford Fiesta, but I don't remember the exact method. But it was something like this.
Try the radio with a USB stick drive to see if the radio even works that way

Sorry thegregbradley, I tried it but it didn't work.
I tried doing a couple of different things similar to that too, and it didn't work either.
As far as using a regular USB drive with some music files on it, it works fine! My friend used her iPod and that worked fine too. I don't see why it has such a problem with Android though...
In doing some reading, I have discovered information that says you need to turn USB debugging OFF for this to work...
Info comes from this thread:
http://www.hondacivicforum.com/foru...nics-10/2012-usb-android-support-88695/page2/
If not that, then I wonder if it's a problem of file management on your SD card? Just as a test, try putting your songs directly in your root folder. Or at most, one folder deep. The Fiesta I rented had bluetooth functionality, so I ended up doing it that way, as it was faster and less problematic. But I definitely would rather just plug it in if it just worked that way.
Iv found that running a rooted rom with debugging off and in mounted mode works great in my car.... No other combo has worked for me
@pwncloud, did you ever get this to work with USB debugging off? Just curious
I have debugging off in my car too and no mods to my android, it's a G2 and I get the same error on my 2012 Civic LX.
To update, no I never got it to work. I've settled with an aux cable.
I have been using an OTG cable (which was not specifically purchased for the N7 - I had one from another device) and Stickmount to mount an SD card reader w/ SD card loaded with videos to view. This, generally, has been working fine, but yesterday I encountered a situation where, while trying to watch something, I was continually interrupted for several minutes at a time. Of course the N7 went into sleep. When I woke it up, I noticed that the SD reader (which has a power./activity light on it) did not get repowered. To restore it I had to unmount it, pull the OTG cable, then reconnect it.
While not THAT big of a hassle, since I was continually getting interrupted yesterday, I was wondering if this is normal behavior for N7/OTG/Stickmout.
Ok, this is a bit strange. I replaced all the hardware components (excepting the N7 itself, of course) -- new OTG cable, new portable SDHX/SDHX Micro reader and the card and it is doing the same thing. The reader has a power light on it, that remains on when it is in use. When the N7 times out (I have it set for 2 minutes), the light on the reader extinguishes as well. When I wake up the N7, the power light on the reader does NOT come back on. Stickmount reports it is still mounted and I can traverse the tree to get to it with a file manager. However, when I try to access anything on the card, it errors out.
I repeated the test with a standard USB drive (a rather small one that would not do for what I am trying to accomplish -- media storage/play to save on space on the internal "SD" card). When the N7 timed out, the light on this unit remained on. I was able to wake the unit and continue on accessing the flash drive without issue.
What the heck is the difference between a portable reader with an SD card in it and a flash drive. And, is there anyway to get the reader to behave like the flash drive.
If anyone has any insights into this, I would appreciate it!

At the point where the light does not come on, I would test removing and replacing the media in the reader. Curious if it then works.

Nope, light doesn't come on, card is not readable. Thanks for the suggestion, though...

Interesting. This sounds like the software loading the drivers for the reader are not working. Each version (over the years) of Linux has different ways to mount USB. I am not sure which method Android uses, so I am not much help. Probably someone on XDA knows the details if they will contribute. Or, you might get support from one of the popular Android OTG media sharing app makers to help explain it.
Have you tried a powered (and/or) non powered USB hub in the middle? Curious if your results would be the same.
Unfortunately I don't have one. I NEED to get one, but not yet.
Yea, I noticed the same problem when I was using android vlc to play videos from OTG mounted stick. If I paused and went away for a while, it couldn't resume when I came back. MXPlayer works better, but only because you can start playing the same video again and it will ask if it should resume where it left off, so at least there is a way to get back to where you were after remounting the stick.
If I copy the video file to the local /sdcard storage, none of these problem with sleep crop up, so it is definitely OTG that goes funny in the head.
Hello:
I have owned a XPeria Play R800i for about 2 years by now. After the first week using it, I installed the Gin2JellyBean ROM, and updated it to version 1.8.1 - And have sticked with it since. Everything worked fine, until yesterday.
While I was charging my phone (it always gets a bit hot when doing so), I had to disconnect it and use the flashlight for about 30 minutes. I could felt the temperature rising, but after such a long time using it, I thought it wasn't anything to care about. Suddenly, the phone rebooted by itself, and as it was very hot, I decided to leave it near an electric fan so that it would cool down.
An hour later, I checked the phone and everything looked alright - I could browse the web, and use some apps. But when I tried to use the gallery, an error appeared: SD Card can't be found. Then, I noticed that all the apps that I had moved to the SD appeared as grey icons, and when I tried to open them, another error message.
I thought that something bad had happened to the card, so I removed it and put it on my PC. And it worked! I backed up all the files, reformatted it and tried again, to no avail. In Settings/Storage, the options Mount SD Card and Format SD Card appear greyed out.
Tried mounting it using the console, and no luck.
Can you help me? Do you think it might be a hardware error? Is it fixable?
