Usb Device Not Recognized Using Samsung Galaxy S2


Ok so my samsung galaxy s2 was working fine, i had if for about 4 months and i had connectivity with my laptop running windows vista home premium. However last week i updated the software and was trying to update the firmware via kies when i got the error - usb device not recognized. One of the usb devices attached to this computer has malfunctioned, and windows does not recognize it.

On the phone the mtp initialization appears then shortly says connected afterwards. However windows cant see the phone. I believe i have tried everything to resolve this, i have;

A) done a factory reset on the phone.
B) re-installed the latest version of kies and drivers ensuring everything , including drivers and associated files were wiped from my computer
C)tried different usb cables including the oem cable and various aftermarket ones.
D)tried all the usb ports on my laptop.
E)tried other laptops and desktops.
F) tried de-bugging mode.

I'm sure there is a g) and an h) but can't think at the min. So does anyone have and ideas? I'm starting to think the phone is faulty and send it back. Many thanks in advance for any suggestions.

Micro Usb To Hdmi - Samsung Galaxy Nexus

Does anyone know if the gnex can utilize a micro usb to hdmi cable? Or do you have to use a micro usb to hdmi mhl adapter? I really hate the bulkiness of the adapter, but i'm not sure which i can use, or which will support 1080p output. Anyone think they can shed light on this? Also, recommendations are very welcome

Update: after purchasing an mhl adapter from monoprice and getting a replacement that had the same problems, as well as doing a bit of research online - there seems to be an issue with either monoprice mhl adapters for our phones or all mhl adapters in general and i don't know why. If you have an mhl adapter whether monoprice, samsung, or any other brand - please post your experiences.

Kies / Usb Mode Issue - Samsung Galaxy S2

Basically for the last month or so when i try to connect my sgs2 to the computer to use kies i get the message. "Unsupported connection mode alert reconnect the device in samsung kies (pc studio) mode. Current connection mode not supported by kies. "

I wouldn't really care as kies is rubbish in my opinion, and it is a lot easier and better to use the phone as a mass storage device, but i have been waiting patiently for the official ics update and now it is finally landing i am unable to update without kies. I have checked the usb debugging is not enabled, i have tried all solutions i can find (turn usb debugging on connect and let load drivers, unplug and turn usb debugging back off and try again), (uninstall and reinstall kies), etc etc. There are a lot of things i have tried but nothing is working. Also i assume it is something to do with it, but i know i used to have 2 or 3 options when i go to settingswireless & networksusb utilities. But now there is only one, "usb mass storage".

Cannot Encrypt Device - Samsung Galaxy Nexus

I just restored to stock 4. 0. 2 and locked my phone (it was repaired and sent back unlocked). I'm going through the regular setup routine and when i try to encrypt the phone, it just reboots and nothing happens. I go to the encryption settings, select "encrypt this phone" and then enter my pin. I confirm again once it sees that i'm plugged in and have enough battery, but then the reboot happens and i'm back to the home screen. Anyone seen this? I'm on gsm. I had no issues encrypting on 4. 0. 1.

Usb Port Problem - Phone Going Into Car Mode Randomly - Samsung Galaxy S2

Ok, i'm not sure how this hasn't blown up yet but this is a huge issue and in my opinion it should be getting way more coverage. If you're having these problems:

1. With your phone going into car mode randomly
2. Always having speaker phone activated
3. Randomly connecting to kies when it's not plugged in
4. Randomly saying it's charging when it's not plugged in
5. Freezing, getting really hot, then loosing about 25% charge

Then you have a problem with your mini usb port. It is not a software problem. I've seen this happen to 3 sg2's including my own. I have been able to fix all of them by cleaning the port with rubbing alcohol. 2 of them unfortunately relapsed. I have no idea why or how this problem is so prevalent but it appears to be affecting a lot of people. What can be done about this? It seems like it is faulty hardware and not an issue with people just being careless with the port. I hope this clears up some confusion that people have.

Bluetooth Device Crashing Phone After 2.3.5 Update For Samsung Galaxy S2

I never had issues with my phone until i updated to 2. 3. 5 and one day i accidentally turned on bluetooth got a notification about bluetooth devices and it just crashed. After that it would reload to lock screen within several seconds but the bluetooth will automatically turn on again and proceed to crash my phone.

The only way i have stopped the crashing, is to put it on flight mode. Which is no good as i can't use 3g and cannot receive calls or call. Really frustrated that i cannot use a phone to call! Any help would be appreciated, thanks.

Adding A Usb Wifi Adpater To A Dead Android Device

How to "activate" a usb wifi adapter on an android device (2. 3. 5) that otherwise does not have internet access. I need to add a realtek rtl8188su wireless lan 802. 11n usb 2. 0 network adapter. (That claims to be linux compatible). I just don't understand the driver install process for android. The device i speak of is a mobile media station made to replace a car navigation unit. So it's not a phone with cellular access so finding the driver in the market-place is not an option. The mms has 2 usb ports and 2 sd ports. It runs with windows ce by default with an option to 'goto' android. Which of course was my reason for the purchase. When simply pluggin in the realtek (and other adapters) i get the word "error" instead of a list of networks. Any light you can shed on how to "active" the wifi adapter will be gold. I've been at this for a week now with no luck.

Motorola Droid - Not Recognized As An Internal External Command

I just rooted my droid using this guide, installed busybox then made a custom recovery. I know how to use the change directory properly cause i did it enough times doing those things, so i'm pretty sure it's not that.

http://androidforums.com/all-things-root-droid/45764-guide-s-everything-root-related.html

After that my command prompt stopped working for me when i wanted to start doing stuff. It gives me that error; "not recognized as an internal external command, operable program or batch file"
I'm not sure why it's not working for me, not a tech savy guy really, just know how to follow tutorials.
I'm thinking it may be my path variable needs to be fixed some how, but i don't know much else about it, so i haven't touched it.

Htc Evo 4g - Wav Format Not Recognized After Froyo (2.2) Update / Get It To Work

So i have read online that with the 2. 2 update, the music file format ". Wav" is no longer recognized. In 2. 1 this worked just fine since i can confirm. People who get email notifications with wav file attachments or open small wave on the web are unable to listen to them if they have froyo 2. 2 ota update. Does anyone know if this is a bug that is being addressed by android team?

I don't want to download 3rd party apps just to listen to wave files. I want to use the exiting music app on the evo.

Samsung Behold 2 - Sunkist And Usb Debugging

A couple of weeks ago my daughter (3 years old) turned her mommy's sunkist over on the coffee table which happened to be where my phone was sitting since the night before. Needless to say i freaked out a little bit. Luckily the battery had died and there was no power to the phone at the time. After pulling everything out of it and laying it on a dehumidifier rack (one you put in your basement not the one you make jerky in) for about 2 days so it would dry out. When i turned the phone on it worked and i was happy. I did notice that i had some issues with charging but for the most part it worked. The usb debugging notification would come on when it was hooked only to a charger which is wrong. This went on for a day or so and then stopped.

3 days ago i had the phone on the towel rack in the bathroom while taking a shower. When i got to work the phone would not shut up. It is constantly in and out of usb debugging. Any time i touch it it goes nuts. This primarily happens here at work. Very seldom does it happen at home. I disassembled the phone, removed the back cover, the battery, sim, sd, took the screws out of the back, pulled the boards apart at the top and cleaned them all with pipe cleaners and alcohol really well and reassembled the phone. It is still doing the same freakin thing.

My question is. How is usb debugging initiated hardware wise? I know you go to apps>development and all that jazz to enable it. My question is what exactly happens within the phone to signal that it is time to initiate a connection. The phone doesn't think it is charging when this happens but it does reset the "time since unplugged" counter whenever this happens.

Any clues? Also, what else can i use to clean the internals of this phone that will remove any type of soda drink syrup. I have a feeling that there is a connection happening somewhere that is based on localized moisture content of surrounding air. Sunkist contains a fair amount of citric acid which when allowed to dry creates more resistance in a circuit. When exposed to even small amounts of moisture can open a path for current to flow.

Samsung Epic 4g - Micro Usb Chargers Are Not Alike

I was under the distinct impression that the micro usb chargers and cords are being made today on a universal standard and all new build phones starting in 2011 will have that port as standard. I have some micro usb chargers that won't charge the epic when turned off only "on". In fact if my phone is off and i plug in the charger the phone turns on by itself. Now this is not a samsung charger but why do you suppose the phone wont charge with some of these chargers turned off?

Samsung Epic 4g - 2010 Prius Usb And Bt Not Working Well

First post. Just got epic last week. My car is a 2010 prius with navigation (bt audio capable along with usb connection). Two issues:

1. My samsung epic suffers from horrible bt audio streaming sound quality! My itouch (from apple) bt audio was perfect!

2. And for the life of me, i cannot get the prius navi/audio to recognize any music files on my epic via usb connection. I never had this issue with the itouch. (And yes, my music is on the microsd card. ) I have tried everything that i can think of. It just won't see any music files! I tried copying music with doubletwist or just straight to music folder. All no go.

Sprint/samsung is damn lucky that the epic gets good signal and call reception/clarity is the best that i have heard. Because otherwise, i would dump this android phone like yesterday's news! So, now, i have my epic on my waist for phone calls and my itouch doing bt audio streaming in my car. Hmmm, i thought that my whole point of going to a smartphone was to have just one device for everything.

Samsung Captivate - Usb Mounting Issue On Both Windows And Linux

I'm having issues having any pc recognize the storage media areas of my brand-new samsung captivate s. When i first got my phone last week, it had no issues in my linux system in mounting both the internal and external drives on my phone. I don't know what i did, but now it no longer works.

On the windows side of my machine, i did install kies. It has installed the device drivers for my phone and the phone did get recognized in kies desktop.

Now whenever i plug in the usb cable and mount the drives via the pull-down menu, nothing happens! On the very very rare occasion it does find the device, the drives stay mounted for about 15 seconds or so before it completely disappears!

I've tried both in and out of debug mode.

I don't know what else to do. In my research, it seems like others are also having problems mounting the drive(s) via usb cable.

I've reset my device to factory defaults, and have formatted my internal card. Still no change in behaviour. I know my microsd card works fine. I've pulled it out and plugged it into my sd adapter and my computer reads it with no problems.

I'm running ubuntu linux 10. 10 and xp sp2 32-bit edition.

Samsung Behold 2 - Device Management Not 40mb Any More

I have noticed in 1. 6 that when i manage applications, the previously huge device management data is no longer 40mb, so i don't have to delete it any more. It's more like 40k. So it has freed up a bunch of additional space on my phone now for apps, which is most certainly welcome.
