USB Problems Since Upgrade to 2.2.1

Since upgrading the Galaxy S to 2.2.1 which I absolutely love - must faster than anything previous, sleek, really well done, I've just noticed for the first time that my USB doesn't seem to work.
The computer sometimes sees it but just says the device is malfunctioning, the phone sometimes sees the PC and gives a menu for "ask on connection", but Windows just does not know what this device is at all.
Suspect I may have to reinstall the drivers fully in Windows, remove it completely and try again, if it actually showed up as an unknown device in Device Manager.
I do need to try another PC and cable just in case, but this is what Im having at the moment in Windows:
USB Device Not Recognized
One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it.

And the Phone is currently not detecting any connection.
Any thoughts?

I would go with a windows problem and remove the usb drivers/Kies .
Followed by fresh install .

You can find a link to the usb drivers in my signature.

I think its a little more problematic.
I've tried another computer, another OS and another cable no joy.
I've installed aLogCat and Im getting:
Intent Action android.intent.action.ACTION_POWER_CONNECTED
Battery charging.plugType = 1
AC Charge
In MtpReceiverandroid.intent.action.ACTION_POWER_CONNECTED
Battery charging.plugType = 1
Not of USB charging. Dont lauch MTP APP

I've done a quick search on this. Hopefully this is as simple as doing a factory reset and format the internal sd.
If not, then Im off to a samsung service centre I think.
Any further thoughts?

:-(
Factory reset the phone, but the USB port still is not working. Charges fine, but don't connect over USB to the PC.

Can it be in debugging mode. Try to switch between mass storage and kies.
Probably you have checked that already..

the same problem from me i tried all but the usb is not working at all. I flashed kernel , i flashed rom but nothing .
Now i am looking to install untouched rom in order to give it to service but when i am trying to flash from recovery i get an error . Any suggestions?

This may sound dumb, but it could be the USB port acting up (loose connection). Try wriggling the cable around or use a different port.

I test the usb in all the modes (recovery and download also). I used different computers but the same thing

Right, I've tried all available USB ports, two different computers, two different OS's. The phone just does not register a USB data connection. It only recognises AC charging according to the logs.
I think I have a broken USB port on the phone as if I jam the connector in at an angle on the phone, it sometimes registers the data connection but its far too unreliable.
Development mode don't work, Kies, Mass Storage etc... anything. Nothing works.
Factory reset doesn't make it work.
I can't even flash a new ROM as the phone is not detected in download mode.
I've got the phone booked in at a Samsung Service Centre now. I've seen a few webpages referencing corrosion. I tell you what though, this phone has been protected way way more than my old N97. I've had so many phones and not one has suffered from "corrosion". So let them just try and say it's my fault. Im ready for em.

Try cleaning your phone usb port. A guy named omersak had the same problem, and he had solved it. Search for the thread started by him, and how he has solved it.
I hope you can solve it without going to the service centre. And good luck.

Definitely trying that first - thank you to all the people that have been doing the investigation.
It sounds to me like Samsung have got a bad batch of USB connectors that should be replaced under a factory recall.
I don't use mine in a shower, or sauna, or anything like that, I don't even use it in the rain.
The closest it gets to any humidity is being in my shirt pocket from time to time.
Im going to get some meths or something like that and some thin paper and see what I can do with that. Im just off to Homebase!

there are similar problems on the galaxy 3 series where usb suddenly stops working. the following solutions seem to work there:
1. dial *#7284# to open "PhoneUtil"
2. in USB section, switch to modem, and then switch back to PDA
if that doesn't work: reboot into recovery and select "wipe cache partition"
*hth*

I've tried both of those before I start splashing the methylated spirit around. Still no joy.
Wipe Cache don't work, as well as wipe data/format sd/restore factory defaults etc.
I think I've got a 100% hardware fault.

@OP,
I am terribly sorry about your case. Looks like you need to make that trip to the service centre.
At least you have tried out every possible means known.

Also tried the meths. No good. :-(

The USB just started working yesterday. Still a bit intermittent, but when it gets a connection, it maintains a connection.
I've just ordered some isopropyl and a gold plated USB connector to be on the safe side

Hi everyone,
To sdjean: maybe you could read the post I sent a few minutes ago:
forum.xda-developers.com/showthread.php?p=12593413#post12593413
It might explain why your usb data connection does not always work ...
Regards.

I have a Samsung GT-I9000B and I cant use it using USB.
I have 2 usb cables, I am able to find my friends phones.
Now I cant change rom cause odin cant find it too.
Alog cat shows:
E/MTPRx ( 4020 ) Battery charging. plugType = 1
E/MTPRx ( 4020 ) Not of USB charging. DOnt launch MTP APP
Any suggestion?

I'm not an Expert but 2 hints from me:
1. If you have'nt tried yet: Install usb-drivers on pc new and then connect your phone and wait until drivers are installed to your phone.
One times this way worked on my i9000.
2. Look for a zipped rom on xda which you can directly download and install from sd-card.
Sorry, I know my English is bad.

Cadillac CTS USB

Hi guys,
I know it sounds a little strange posting something like this in here but anyways her is my problem...
I just got my new cadillac cts and i am trying to use the usb feature which u can plug ur harddisk and usb flash and it will read all the mp3 files and u can play them directly from car.
So whenever i plug my xperia play it will say unrecognized device i tried both mass storage option and media with no luck. So my bro has nexus one connected it worked without problem ;/
So if you have any idea whats going on please help me out.
I am thinking it may be because the xperia connectivity settings which is different than other android devices so is there away to disable the auto mount from the settings and try a usb app from the market.
Thanks 4 ur time.

I couldn't get my Atrix to work in the CTS either. Did you ever get it to work?

Use bluetooth
Sent from my R800a using XDA Premium App

Remember that there is a certain lag between connecting it in Mass Media Storage and it being recognized. You'd do well in disabling the PC Companion prompt as well.

Anyone have any luck getting an android phone to work with the CTS?

so I have to restart every time I want to access a usb drive ?
I thought they might have automounted etc.
I have'nt tried a digital camera yet , but , if I connect my usb drive then unplug it , i have to restart to be able to connect my digital cam ? , does'nt sound good ...

I am having similar issues. I can plug a drive/ stick in 3 times at the most. Then I HAVE to reboot for the xoom to see anything else. I hope someone fixes the issue. Friend of mine is having the same issues. Use brd method of updating and rooting. 3g model
P.s. USB mice and keyboards are not affected. Just drives/ sticks with data.

[Q] Audi Music Interface AMI compatible?

Hi, I've just had a new Audi A4 with the AMI, I was hoping I could plug my Hero in and have it read it like it does for iPhone/iPod, but it doesn't seem to.
Is there any way of making the phone compatible with the AMI?
thanks

I don't know anything about AMI. Does it have Bluetooth A2DP? My BMW has this and I can pretty much stream any audio from my phone to my car's sound system.

it's got bluetooth and it downloaded my phonebook to use, but the AMI is a cable that plugs in to the phone

Turned off usb debugging. Also I found directories on my bmw cannot be too deep on sdcard

USB debugging helped me

I assume the USB debugging as I've not changed the directories and before I switched it off I was getting an error in the car saying not a compatible device

USB Mass Storage for Car Stereo

Just picked up the G2 a couple days ago. I've owned an Android before but never got into the rooting and rom flashing process. My problem is mostly that I used my iPhone in my car (a Kenwood head unit) for the stereo. I was able to control the music and sounds via the phone. However, the G2 doesn't work this way. Most I can get so far is the ability to select and play songs via the headunit, which with 1000+ songs is extremely inconvenient. I owned a Samsung Infuse years ago and that was able to work, but it was done by selecting USB Mass Storage I believe. I've done some research but I can't seem to find a straight answer on how to go about enabling that. Is there any way around this? It be awesome to be able to use my phone in the car.

What's the model of your car stereo? Maybe you can connect it with an AUX cable or Bluetooth, if your stereo supports it.

It's a Kenwood MP345-U. It does have an aux cable, however there is sound quality loss with that. Bluetooth I'm honestly not sure whether or not it has, I've read somewhere I can purchase a Bluetooth USB that the phone can connect to. My main concern was I was able to charge my phone before along with it pausing the music during a phone call, etc.

Since the phone can function only in media player mode (MTP), I don't think you can play it any other way than through the AUX cable. CWM recovery has the option of mounting internal storage as USB storage, but that's a highly, highly impractical solution.

You CAN do this but it is specific to CM ROMs. Probably 10.3. I don't know if its working on CM11 KitKat yet.
Its called USB Audio or something.
I'd also check out a Bluetooth solution if it would work. Then you could just plug in audio and use an NFC sticker to turn on BT and launch a music player. If you have a Verizon, you can also do wireless charging, so you can just drop your phone down on a mat and have everything just start working automatically.

There is only quality loss with anything OTHER than AUX. The AUX and only the AUX on this phone is capable of delivering 24bit audio. The downside is, well, 2 cords.

Problem Using Bluetooth
The problem with using Bluetooth is that you can't use voice commands to pick tracks to play.

I did that. I enabled MTP fix rebooted and plugged in,what I did notice is that it seems to mount for a second or 2 sometimes and then it unmounts right away. I tried it on 2 work computers also and under my computer, the LG pops up as a drive for a quick second and then it un mounts. What the heck is going on.,I have screen shots of what is happening.It always pops up on the top of the screen with SD Card Unmounted when I tap the widget to mount. Something is causing it to Unmount it appears, any ideas?Since I Rooted the phone, when i hookup the usb cable it says that i am connected as installer, could that have anything to do with it?
