[Q] USB device not recognized

Hi all, Ive had my captivate for about a week now and have been playing with it, I've been all over the web trying to figure out why I can't sync it with my pc Ive tried both my laptop with windows 7 and my desktop running XP. Nothing will work ive downloaded the drivers from Samsung's site and kies and kies mini with no luck. No matter what i do it says device not recognized windows has stopped the device and nothing shows up on the phones screen it just shows its charging, I'm guessing its something I'm doing but i just don't know what. Once I had so much trouble I connected a Samsung flight to my PC that's running XP and it worked just fine. Can anyone help me out i want to root the captivate so i can get take off all this att crap!!!

Did you mount the phone after plugging it into your computer? You should pull down the notification bar and it should give you the option to copy files to/from computer.
Also, set you usb settings to mass storage. It's in settings...can't remember where on stock.

Yes I have put the phone in all the different usb settings debugging,media player, mass storage, ask on connection, kies. When I plug it in the only thing that changes on the phone screen is its showing its charging it doesn't give me any option to mount. The same cable will connect my old Flight phone and that phone transfers files just fine. This really has me stumped.

You downloaded and installed drivers from this site? http://www.samsung.com/us/support/downloads/SGH-I897ZKAATT
This may sound random and stupid but are you plugging into a USB that is directly connected to the motherboard (back of the computer)? If you're on a laptop there is no way to test this...basically, there was some issues before of people not having their computer recognize their phone and the issue was too low of power from the USB.
Hopefully someone else can chime in as well. I'm pretty new to this too so I can only think of fairly basic things.

Windows 8 Support

Is anyone else having trouble getting their Samsung Galaxy S III (Verizon) to be recognized in their Windows 8 PC as a media device? I have explorer functionality when the phone is in camera mode but in media mode it does not appear in Computer.
I tried the phone on a Windows 7 PC and it works just fine, plug in play. I have downloaded the driver available on Samsung's website, but doesn't have mention of Windows 8 compatibility and during installation also prompts many messages of compatibility issues.
Thanks for your time and any help.
Also, the although I have file explorer functionality in USB camera mode, I am not able to transfer songs to the phone and a message is displayed by Windows that while in camera mode this type of transfer (music) is not compatible.

Did you try Kies air or try to somehow put the phone in compatibility mode to windows 7/vista?

For me MTP doesn't work well at all.

mine works fine.....I can see both internal and external sd cards and all the files on both of them.

Worked fine for me out of the box. Plugged it in and windows downloaded the driver, wanted a reboot and was fine since.

Works for me

works perfectly for me

Mine shows up but if I send over to many files at once it crashes the explorer.

Thanks for your replies guys.. I tried connecting the phone again to the computer this time into a different USB port and walah.. it shows up as a Portable Media Device. I'm back in business.

[Q] Cannot "Fastboot USB", cannot ADB...

Hi all. I have a unique problem here... not sure if it's a software of hardware issuse. Maybe you can help me out.
My phone can read all storage space while I am in the operating system. Internal storage reports as 2.34GB, SD card (also internal) reports as 9.92GB. I have no problems copying, reading, and deleting files using "es explorer" or transfering files via various wifi file tansfer programs back and forth with my desktop.
The problem lies with the fact that I cannot use the USB port at all except to charge. Even in HBOOT the computer doesn't read it! For example, if I connect the phone to the computer while it is in HBOOT and select FASTBOOT, I do not see "FASTBOOT USB", it just remains as FASTBOOT. ADB from my computer cannot detect the phone either. I have tried all my USB ports, installed HTC USB drivers, Android SDK (and associated USB driver package), tried a different computer, tried 4 different USB cables, but none of this works.
What is strange is that yesterday the phone suddenly worked via USB! I was amazed that after 2 months of it not working it just randomly started again, but figured I did something random to make it work. Then I unplugged it and then re-plugged it and now it doesn't work again... Absolutely awkward, I hope someone can help me at least identify what the problem is!
I'm currently using the latest Cyanogen 10.1 mod (March 12th), have it unlocked, and am using CWM 5.3.6. I would really appreciate any insight or help, thanks so much in advance.

OMG now it's working again. A constant factor seems to be the use of "AirDroid"... Whenever it is open and transfering the SDCard becomes recognizable and the computer can connect... Very awkward... any ideas as to the issue?
I'm scared to touch anything on it. It's transferring some music via USB.

Now I unplugged it from my computer and the re-plugged it back in and it no longer recognizes my SDCard at all... What is going on? It seems like a software issue but what could it be?

Well now it works. I plugged it in and nothing happened so I walked away. When I came back it was asking to turn on USB mode! I wasn't using any wireless wifi transfer programs, it was just in regular home screen mode and that's all... it just decided to work... huh. This appears to be random but it can't be... there must be some reason.

Well it's still working, but I haven`t unplugged it yet. The phone rebooted itself mid-transfer for some reason, but it still can be used as a USB drive. It seems that after I had begun using the internal SDCard to store stuff on (first via wifi transfer) it has become more "recognizable" through the USB connection... Could there be something wrong with the internal SDCard itself and not the USB connection? Can I reformat it to start with a clean slate?
Like right now my card is using 90% of it's storage... and it's been more recognizable now than ever before... I used to keep it at about 10-15% usage...

Okay, now after I have transferred a bunch of songs and movies to the SDCard, I rebooted the device with the USB cable still in and now it isn't recognized at all. I changed absolutely nothing; the phone was in USB mode being able to transfer files back and forth, then I rebooted and all of a sudden the USB mode doesn't work again... Not even recognized... no ADB recognition... no Windows recognition... nothing. So strange! What could be the problem?

Well it looks like it was my actual computer. I am connecting flawlessy in USB mode to the phone with my Dads computer. I guess I have to get a new motherboard as Ive always suspected mine was on its way out.

SOLVED
Looks like the issue has been solved. After having tried many different computers, it seems as if certain computers have success with reading and recognizing the HTC than others. For example,
My personal computer: Works rarely
My Dads: Works flawlessly everytime.
My Garndmas: Works intermittently (better than my personal one)
My Moms: Works flawlessly
Now I just wonder why some USB ports work and others dont! Any ideas?

[Q] adb slimbean 1/2 connected

I put slimbean on my buddy's infuse. (kickasp rom and phone btw) i used odin and had no problems.everything works and cwm, all works. problem is when connected to my computer (windows xp) it shows up as mass storage and i can view both the internal and external sd cards. but, when i plug it in i get the sound that you get when not connected properly (hope you understand that) and adb doesn't see the phone at all. i don't get the prompt on the phone to allow the computer to connect. (i may have got it once and don't remember though, but i would have accepted)
i have reinstalled the drivers multiple times and from multiple different sources. all other phones i plug in adb connects just fine. he assures me that he bought the cord that is specific to that phone although i never had any problems with my skn6380a cord.none of the parts are damaged.
im sure the answer is here somewhere but i have been through about 200+ pages so far in different areas here and haven't found what i'm looking for. he wants me to unlock it and i have a tool that will do that and i have a hex editor and a plan b too! also tried an adb over wireless app.

Umm well I build slimbean and use adb constantly so I don't believe its a problem with the ROM. I'd suggest trying a different cord if possible and different USB ports. Try adb kill-server then adb start-server then adb devices and see if it shows up.

G2 won't allow MTP on Mac

So this is very strange. When i use to plug my G2 into my mac and use Android File Transfer everything worked fine. Recently, I went to transfer some files over and I plugged my G2 into my macbook and it automatically chose the "PC Software" option and says "Installing PC Programs, check your computer." I go to select Media Sync (MTP) and it just automatically goes back to the PC software option. When i click Android file transfer it just tells me to plug in my USB. I have my drivers installed for my Mac and i've even tried it on my virtual terminal and the same thing keeps coming up. It's so annoying bc it use to work just fine.
Someone please help me

Have you tried a different USB cable?

Ya and same thing keeps happening. I am using the cable that came with the G2 when I got it. The same cable that I used when I use to be able to send stuff back and forth between android file transfer. It's very very strange
