For those having driver install issues

The first thing I tried to do when getting my Vibrant 2 days ago was to try to install drivers, wasting hours and hours and getting nowhere (all I wanted to do was to copy the rooting zip to root the phone). Yesterday, I tried turning off my USB Debugging, and then mounted the SD Card(s), and they both worked as they should. Great, so I can get my computer (Windows 7 32bit, FYI) to recognize the drives and copy files (by then, I had already just copied the file I needed to via just taking the SD card out, phone has already been rooted, but now I was thinking about tethering).
So today, after having done a lot of searching the past 2 days, and having come across a post I found on another forum (sorry, I'll have to go do more searching to find it again) where someone suggested that one of the issues might be the USB plug on the computer not being a powered one (this was front USB port on a Gateway computer), I plugged the cord into a powered USB hub I have, turned USB Debugging back on, plugged the phone in, and the driver install went a bit further than it did before, at least recognizing the device, but not installing the drivers. I went into device manager on my computer, pointed the 2 unknown devices to where the Samsung Drivers I downloaded off of Samsung's website were and everything installed perfectly. Phone is now recognized when plugged in, and the SD Card(s) mount just fine.
Since that was a major reason to keep/return the phone, I'm happy to have discovered the solution to 2 days of research. I thought I'd share this in case anyone else might be having issues with installing drivers for the phone.
Now to see about the battery drain and some other potentially "minor" issues and see about it really becoming a keeper (coming from a MT3G, it is a major upgrade, so it's just getting used to the differences).

I had an issue with USB Debugging on too.... so I thought, then I realized I was using the Nexus One cable and not the Vibrant cable. I turned off USB debugging and used the proper cable and everything was automatic.
Interesting read, thanks for the post. Perhaps I need to tweak the sticky some.
edit: added this thread to the sticky. Thanks man.

Interesting note about the different cable options, I had read that some cables were "better than others" - I had to use the micro USB cable that came with the Vibrant, so I knew that wasn't an issue, figured I'd tried everything else, so what the heck (thought I swapped the USB plug last night, but turned out I swapped the wrong cable, lol).
I did order a bunch of generic micro USB cables from ebay (2 different sellers), but I just need those for charging (like for the car, for my travel back, etc), I'll stick to the Samsung cable for data needs and likely test the others in case I need a backup.
Your main thread was definitely helpful, and I just wanted to share a potential solution to an issue I had seen others post about without any resolution (actually, the person in the other thread had a slightly different problem than me, and never claimed solving it by changing to a powered USB plug).

Please Help! PC won't detect HD2

Hello
I've got an HTC HD2 tmo US...
When I plug in the sync cable from the phone to the PC, simply nothing happens.
The phone charges but Mobile Device Center shows not connecting and nothing about detecting hardware or anything, when I set the phone to ask what to do (ie. Disk Drive or Activesync) It also doesn't ask anything when plugging in.
Any ideas?

First check the phone with another cable. Are you using the supplied USB to micro or another cable - like a retractable? I made the mistake of buying a retractable that wasn't fully wired to handle data.
Uninstall Activesync and reinstall with the phone disconnected - they once the install is done reattach.

Hey
Yup, I tried another cable, both are official HD2 cables or OEM...
I have also tried another PC (32bit WinXP) - still no detection.
When I press volume down and power for 3 seconds, it gives me that tricolor dislay, i tap it and changes to USB, my PC then sees the phone (but of course not usable).
So I think it's software related, I'm trying to flash with the SD card, but so far it's just stuck on Loading....
Any other suggestion you might have perhaps?

I've managed to figure out it seems to go into car kit mode everytime I plug in the sync cable, and NaviPanel pops up some times. Looks like it's a tad buggy though cause it won't go away and then it goes away and comes back, etc.
Any ideas?

stuck in car kit mode is indicative of a faulty usb port. some people have had success by cleaning out the port with various means,,, compressed air, wd40, toothbrush, one aguy even spat in it.
mostly, though, it requires a warranty repair.
theres a thread "stuck in car kit mode" in the regular hd2 general section.

That fixed the issue! Toothbrush, yes I failed a few times, just kept watching the screen and got really in there hard and dirty on the top small gap, and wala- the light came on while it was locked and it worked.
Is this a permenant solution though? Is it really only dirt and something that is just for maintenance sake or should I be worried the hardware is faulty or on its way out?

Sorry, couldnt say. Sent mine away for repair and they swapped out teh whole board. Plus minewas deffinately clean as a whistle. It seems some people have dirty slots, some have hardware faults.

Have you tried messing with the USB to PC settings?
Settings > Menu > All Settings > Connections > USB to PC > Either pick Activesync or Disk Drive.
Sometimes my computer doesn't do anything when I plug in my phone using Activesync. I would have to open up Windws Mobile Device Center and detect it manually.

[FIX] For those that haven't been able to get to Download Mode

If you are having problems getting to download mode, Use the Stock Captivate Cable Only when trying to access Download mode!
Story:
I have struggled with 2 captivates now to get into download mode. I have read tons of arguments back and forth from people that say it is easy to get into download mode, and people who say that it is impossible with their phones.
Well, for some history...On my first captivate, I bricked it and it refused to go into download mode...PERIOD. I proceeded to exchange it(I was within my 30 days), and didn't think much more about it. Well, I installed Cognition 2.2 recently and in the process realized that my new phone would go into download mode just fine by doing the standard process of:
1)remove battery, sim, microsim
2)reinserting battery only
3)holding down both volume buttons
4)inserting usb cable
No problems right? Well, I ended up "bricking" my phone by accidentally deleting my framework-res.apk file(don't ask) and lo and behold, I suddenly could not get it to go back into download mode. I was really pissed at this point and spent all night trying everything all over again.
Well, I decided to give up for the night and go to bed. As I was laying in bed a thought crossed my mind. I had purchased a second usb cable(from ATT) to use with the captivate, and the one time that download mode had worked, I was using the standard captivate cable that came in the box. However, every time it wasn't working I was using my second USB cable. So I got up out of bed to try the stock cable and, lo and behold, it works flawlessly every time.
I would venture to guess that this is what the problem is with most everyone else that can not get their captivates to go into download mode. So, if you haven't tried it give it a shot. And certainly tell everyone you know to use the stock cable only.
I just want to reiterate that the spare cable that would NOT work was purchased from ATT and is the cable that they recommend you purchase as a spare. It wasn't like I got it from ebay or something.

Using a usb cable I got from ebay, monoprice, htc, motorola, and stock samsung cable, I was able to get into download mode everytime...
... also, shouldn't this be in general and not in development?

No USB Hubs or Extenders
RECOMMENDED: Use your stock USB cable that came with the phone.
IMPORTANT: Plug the USB cable into your computers native motherboard USB port (the back of your computer). Plugging the cable into USB switches, extenders or external ports, does not allow the phone to enter download mode correctly.

I can confirm, although i found this out a whilllllle ago, just didnt think much of it lol

Just so you know. I found that in some cases certain USB cables just will not work with some devices. This has to do with the quality of the cable. I would avoid overly thin or flat cables because they tend to be cheaply made and won't be able to provide a stable power flow. The shorter the cable the better.

The cable he/I bought from AT&T is shorter the the cable that comes in the box, and doesnt work, so im not sure if shorter is better

I can recreate this over and over again. The reason I put this here and not in general is because I, like many others, have struggled over and over with odin, and people had the attitude of "it works every time, you're just doing something wrong." The reality is that you're trying to prove that I'm just "doing something wrong" because all your cables work. I can recreate this over and over again. What do you want me to do, make a video of it in order for you to believe that there is an actual issue?
I think it's important for people to see this when trying all the roms and mods that are in the development section. In fact, I think it would be REALLY helpful if designgears would add this to the "how to get to download mode" section on the Odin thread. I can't tell you the amount of hours I have spent trying to get into download mode. It is incredibly frustrating to do everything right, and have others telling you that you are not doing it right.
I searched google endlessly looking for a solution to get into download mode, and no where did I see this as a possible solution. Also, as an FYI, when I plug in the other cable, it just goes straight to the battery screen no matter what I press. I can hold down the power and volume buttons to go into recovery mode, but it's impossible to get to download mode.

I have plugged mine into a usb port in the front of my computer as well as in my monitor. I have never had a problem with download mode or anything else.

While this is good to know...It is quite possible you got a faulty second cable, and some of the cables that do come in the box are faulty as well..
It's always a good reminder to try changing out cables if your having an issues. Same for downloading different things that work for a-lot of people and not for you/me..same too for hooking into the back of the computer and bypassing the external hub....Sometimes you get lucky and find the problem right away..sometimes you don't....It's called a process of elimination...
FWIW..I've never trusted cheap ass cables..in anything. Never have..Never will..but..JSYK..expensive cables go bad from time to time too
Thanks for the reminder

I've also noticed that, on my PC at least, my front case USB ports don't always reliably work with this procedure. I've been plugging the USB cable since into the USB ports on the motherboard.

The thing that throws me off is that this cable works for EVERYTHING else. Data transfer, media syncing, recovery mode, charging, etc... There was never anything that would indicate any issue with the cable. I just want to make sure everyone knows this, because when I was struggling to get into download mode, I didn't see anyone suggest that it could be the cable, even though the cable worked for everything else.

OP - thanks for posting this! It is at least another thing to keep in mind when troubleshooting. I was actually considering getting another cable to keep at work.....
P.S. would we get in trouble for quoting Michael Scott's favorite joke in response to post #6? Yea, I know. Little too obvious right. I'll restrain. Already made myself chuckle anyways

Um.. not true - Although I did use the stock USB Cable - I was flashing the night away (trying to recover my bricked phone) on my Win7 box using a USB hub that had a few other devices hooked into it.
Never had an issue getting to D/L mode.. and it found the phone again and again and again and again.... (go on for infinity).
I think it has more to do with the hardware your connecting it to and how the USB drivers loaded (i.e. XP=****e) and what type of OS your running more than anything. I had terrible luck with my work's XP rig... but my Win7 x64 rig found the device while in d/l mode - found the drivers?!?! and I was good to go.
Although - it is always a good rule of thumb IF you can't get the device to recognize on your computer to use the original cable and hook to the best source of power for your USB which is the back of your computer.
So.. this isn't a [FIX] - just a good tip. If you can't get into D/L mode by holding the volume button and jamming in the USB or using ADB -> Reboot Download command.. your pretty much fux0red.

I need original USB cable
I just wanted to throw in my $0.02 I needed to use the original USB cable and a port directly on my motherboard. The usb cable I bought from newegg does not work with my MSI X58 motherboard and my capitavate. The original cable does not work if I use a front usb port on my Antec P183 case. Strangly an identical usb cable from newegg that I ordered at the same time does work with my work computer, Dell X38 motherboard.

Ive had the same problem... only way i get it to download mode is via Terminal:
su
reboot download
I really cant get it to work no other way :s

I appreciate all your hard work on everything. I read through that post and tried to search it several times... Believe me, I spent hours pouring through the pages looking for something that would work.
No where did I see anyone say to make sure you were using the stock cable because other cables might not work? Feel free to correct me if I'm wrong...there are a lot of pages after all.
Furthermore...I'm sorry to be new to Android and to flashing roms, but we are all new at some point. No one is born an expert.
edit: I'm guessing you misunderstood the post? I wasn't posting about the method...just about the fact that many usb cables, including the micro usb cable that ATT sells, do not work for getting to download mode. If I'm wrong about what you were posting, feel free to correct me. If i'm correct, your post is quite ironic

The first captivate I had WOULD NOT GO INTO DOWNLOAD mode regardless of cable or usb port. I tried every port and every cable including the stock one that came with the phone.
The replacement captivate ALWAYS goes into download mode regardless of cable or port.
It's a tip and thank you for the. But if your phone is one of those that does not have 3 button recovery then it will likely not work with the 2 button download trick either.

Nexus S USB connection issue.

Last week when I plugged my USB cable into my phone, it acted normal. The screen where it asks me if I want to connect USB came up, and I said yes. Everything was normal. It was baller.
Today, that doesn't happen. The screen doesn't come up and all the USB cable does is charge my phone, much like the wall plug does.
I've tried to install USB drivers, but they always require me to find "Android" in Device Manager, and it's never in there. The USB cable is doing nothing but charging my phone.
I managed to add a few mp3s over wifi, just to make sure that was actually working.
The phone is not rooted, (I was actually just going to try to do that) and everything is stock aside from a few apps.

I would really like some insight on this, please.
Do I need to get the phone replaced? Am I doing something wrong?

OK, I new to this, but thought I'd comment. If USB debugging is turned on, my seems to do that.
Settings -> Applications -> Developement -> USB Debugging

sorry to hi-jack your thread!
mine does exactly the same, but all i've done is manually update to 2.3.4 and my usb hasn't worked since, like you i've tried installing the drivers and that's done nothing and its also in usb debugging.
i don't know what to do or how to get it to work again, all my searching on here and via Google don't bring up much

Try another usb cord, and especially if you're using the samsung cord.

Wow, you're right. My HTC cord worked. Thanks a lot.

I have had this happen on to me and have determined that a) the long cable that came with the NS4G is unreliable when used for USB connectivity with my PC. Shorter cables (even the shorter Samsung cable that came with my Epic) work consistently. I am guessing that this is a USB Bus power issue and some people will have better mileage than others using the stock cable, depending on their PC.
b) on a few occasions, it seems I've somehow borked the PC's USB controller and the PC wouldn't recongnize anything until I rebooted it.

Was your phone rooted at any point before the issue? Not sure if they would fix it under warranty for me. I will call Samsung and see.

Thanks, I tried that but no luck. Still need to tried other cords. Also.

My phone developed this problem a couple days ago. I haven't done much to troubleshoot it...figured the port must be damaged.
(Not using the Samsung cable, btw)

It might be the port. I will have to get a samsung cable and try it, but i doubt it will help. Plus i can tell Samsung I tried everything. (I looked a ticket, but they said get a samsung cord, they don't trust the Palm Pre cord i am using).
I had to downgrade to the HTC Hero until i get the phone fixed.

I think I cooked my USB functionality.

Hey gang. Wondering if you can help me with a strange issue I've got. I can't seem to connect my phone to my computer via USB. Wondering if anyone could help determine if there's a possibility of repair or not.
==Possibly relevant info==
Samsung Vibrant
Android 2.2 Froyo
Kernel version: 2.6.32.9
Build number: FROYO.UVKB5
==End relevant info==
So, my USB is acting up. Has been for the last few months, where although it charges when I plug into a computer, it's not connecting to allow data transfer. I haven't been too terribly worried, this happened before then cured itself when I did a factory reset. The thing that usually triggered it was when I tried connecting to my linux box in media player mode. The phone would just kinda lock up, I'd have to restart it and then USB wouldn't connect. But after doing the factory reset it was fine the first time. THIS time however, since I'd just left it stock now I'm itching to flash a custom rom but even though I've wiped the whole stupid phone totally clean, it still won't connect. I'm trying to follow a method on an article on dkszone.net called "Bypass E - Signature Verification Fail Issue On Vibrant Android 2.2".
So it seems I need USB for the debug mode.
What I think my main problem is, and where I need some help, is that I had purchased a super cheapwad USB car charger off of amazon for like 35 cents. Every time I connected to it, my phone would ask me if I wanted to connect using kies, media player mode, or data storage mode. I thought it was annoying but didn't really think it would harm anything. But now that I'm thinking about it, it's probably been pumping 5v into each pin on the USB port, whereas the USB functionality uses probably 3.3v, and I'm afraid I cooked something.
The random part here though is that about 5% of the time it does (sortof) connect. It brings up the USB options when I want to connect, brings up the icon saying it's using debug mode, etc. But my machine just reports that it didn't recognize the USB device. So, I'm thinking it's on the fritz, but figured I'd check here to see if I could possibly find a ray of hope.

You can use ADB over tcpip. There's many a free widget to enable it on google play or Do it manually

Thanks for that, I had been wondering if there wasn't a way to do that over wifi. My issue is that sadly I haven't even rooted the phone. ADB over WiFi requires root, whether I do it manually or use one of those super sweet apps.

So anyways, guess what?
My brother in law has the same phone I do, and I grabbed his phone one day and plugged it into my computers and had the same problem as with my own, and I know he hadn't plugged into the same charger I had, hadn't tried the media mode on Linux like I had (which were what I thought were the big contributing factors). SO, I kept digging, found that I hadn't quite yet cleaned it properly. I'd tried my best to clean it but until I swabbed it well with some rubbing alcohol it wasn't as clean as it should've been.
Long story short, I'm backing everything up so I can start flashing roms.
Moral: just clean the dang thing really well
