Hey, I was just wondering if it's possible that the stock charging cable is able to charge my phone, but has malfunctioned somehow to not let it be recognized by my computer?
Basically I've been trying to get my computer to recognize my phone for a week now.
I'm no expert with this stuff but I'm certainly not a noob. I've been rooted and have been flashing ROMs for months now and have odin'd many times before. Just one day none of my USB drives would work. I formatted my computer, reinstalled my drivers and i know the USB ports are functioning because they recognize other devices.
But when i plug my phone in i get "unknown device" where it used to recognize it once i had the samsung drivers installed. I've tested on a brand new computer, with samsung mobile drivers installed and same result, "unknown device"
Is Heimdall a viable option at this point? I've never tried that program but I have nothing to lose i guess, but someone can save me some precious time if they know it's not going to work, please let me know
P.S. this isn't an issue of not having debugging on or my computer seeing it as a cd-rom, the computer won't recognize the device with samsung drivers installed.
Have you not tried another cable?

unfortunately, i don't have any other microUSB - usb cable to test out. I was just going to buy a new charger since the Verizon store is down the street from me, but I figured I'd ask since I won't be able to go until tomorrow morning
From DroidXcon at AC:
"uninstall the drivers, reboot your computer, reinstall drivers, pull out the battery of your phone connect it, put your phone into download mode and let the composite drivers install...then unplug pop your battery back in , turn on the phone, throw it in debugging mode. and connect and see if it configures"
Thanks Kevin, I've actually been tracking that thread since yesterday and the issue for me is that the composite drivers won't install on its own which is really strange to me as i've not had this problem in the past. I also tried doing everything from scratch on a new computer and got the same results... anyway, i didn't get around to it but will try heimdall tonight and see if anything changes

Mine didn't install on there own either. Win 7 64 bit. Just download them. I just Googler the drivers and found them in a couple minutes no high deal at all.

Thanks for the suggestion. I got it figured out. Turned out to be my charging cable. It charges my phone but won't let my pc recognize it as a device. I tested it out with a coworker's captivate charger and it worked
Some micro USB cables are manufactured only to charge. The rocketfish brand cables from Best Buy, for example. It seems to me the manufactures simply leave out a connecter on one or both ends of the cable, or leave out one of the lines all together. Try another cable.
I just saw your using a stock cable... I'll post anyway in case this helps someone else. Good luck!

So, I just got a HTC HD2 and am trying to connect it to the PC. By the way, did the TMOUSA HD2 ever come with a cd?
I have a vista and tried to download the Activesync 4.5 but it won't allow as I am suppose to download Windows Mobile Device Center. So, I download WMDC and installed it. I plug in the phone and all I get is "USB Device Not Recognized" . PC doesn't detect it.
I have searched everywhere and tried everything but can't seem to get it going. I haven't anything solid to get it to work.
I tried:
-reinstalling the WMDC
-check and uncheck "Enable faster data sync"
Anybody have any idea? TIA
Is the phone charging LED lighting up when connected?
Have you tried another USB cable and/or another computer?
Then you could boot the phone up in Bootloader Mode. It will say 'serial' at the bottom of the screen. Then plug in the USB cable. The 'serial' should change to 'USB'. Then this might indicate that your computer is viewing the device as a unknown device. This device can be removed and your phone, in normal mode, replugged in.
This may not help, but it's worth a try. Vista has a known issue where it just stops recognising USB devices, even basic ones. Plug your phone in via USB and then restart the computer. When it comes back on it may recognise the phone. If this works then it will be okay for a while at least, but you may have to do this again every now and then.
Vista's basically a bug-ridden bag of gash. If you can, upgrade to Windows 7.
Hope this helps mate.

I tried with a laptop with vista (WMDC) and a laptop with xp (activesync 4.5). The led charging light is on, so it is charging but for some reason device not recognized.
I tried the bootloader (not sure what that does) and it says serial and then I plugged in the usb and it still says serial.
Still not working

I think I tried that already but I'll give it a shot again. At this point, I'll do anything lol. I was so stoked in putting android in this too
does any one think a hard reset might help?
It sounds as though the USB controller in the phone is damaged. I had this problem with my HTC Diamond, and searched for ages trying to find a solution. I manged to flash it with a couple of times with different ROMs (from the internal memory via WiFi) - this did not solve the problem.
I am sure that a power surge from a car charger was the cause of the fault.

it couldn't hurt. i would - see what happens.
try checking cabling first or change the cable
Same problem
I am having the exact same problem. My phone can charge on the computer but I cant sync of even access it via the "Disk Drive" setting. I have tried both AcrtiveSync and the Disk Drive option, unchecking fast data synchronization, reseting the phone, and reinstalling WMDC. I have Windows 7 with the latest updates. I have also tried connecting it to two other Win7 machine with identical "device not recognized" results. The phone and cable and practically brand new. Any help would be greatly appreciated. I'm at my wits end with this phone and it has been beyond frustrating.

Try another pc... buddy wid wmdc in it... go for win 7
Sent from my HTC HD2 using XDA App
I am having same problems have tried on a vista pc, my mac and mac running parallels, nothing works. Reckon it is as fred_up says, damaged usb controller which means no NAND Android for me.
Been having similar problems, but seems to have been less likely to occur if I click "Safely remove hardware" in Vista or W7, and remove the device - yes even Activesync (doesn't seem to be available in XP)
Mark
did anybody find a soulution?
hi
did anybody get solution for this? i m having the same problem.
phone doesnt sync with wmdc, nor connect as disk, only charges itself.
message appears "usb device not recognised"
i have done everything, changed cables, pcs, re installed wmdc, even flashed new roms using micro sd....nothing happened.
is this a hardware issue? why can it be charged but not synchronised?
pls help anybody.
Try another Cable. In my case, changing the cable works. Now i m using my HD mini cable with HD2 and it is working well.

thanks,
but i have already tried all that.
today i called a phone repair shop and they told me that
this could be due to two reasons.
1. usb port problem.-in which case it is replaceable for about 15 usd.
2. problem with an IC (?) of the circuit (guess the motherboard) - in which case
it is either not repairable or very expensive.
i ll keep posting as i go and visit the shop.
if there's another solution pls share here.
Some possible solutions to non-USB
Having come here via a search, I'll resurrect the thread with a brief comment. I'm having the same problem, haven't tried them yet but found several promising suggestions:

HTH
solution...
oops...had forgotten all about this thread, until today till i received the notice about new reply.
thanks for resurrecting the thread.
actually i went to that phone repair shop i mentioned earlier and they fixed it by replacing the usb port. still it didnt work with win 7 laptops. but was fine with xp laptops. dont know why...anyway i have said good bye to my hd2 long ago & using android now
guess lots of people are.
good luck to you all.
I've had this awesome tablet for just a day and loving it so far. Only issue I have right now is when I connect it to my Windows 7 PC, it is not detected at all. I have installed the PC suite (EeePAD_PC_Suite_v1_0_37.rar) which is suppose to install the requisite USB driver, but no luck.
It charges fine when I plug it into the wall so the wire is okay. Any ideas what maybe happening?

Most phones come with the drivers on them to install most functions when plugged in via PnP. I would test and see if uninstalling what you installed and then trying does. I could be wrong though. This is my first tablet and I don't have it in hand yet
i noticed that mine doesn't charge yet it does connect...make sure you restart too
I was told it will charge just at a much slower rate.
Problem solved. I did a bunch of things so I'm not exactly sure which one really fixed it. But rebooting the tablet seems to have done the trick. Also, the front USB ports on my PC have gotten a little strange. If I plug the USB connector all the way it wont work. I have to pull it out ever so slightly to get a successful connection.
Thanks for the quick response guys
No Matter what I install It still shows as an MTP device and that's it. Can not see it in any version of Windows.. any one have this issue. thanks
I got mine to work by using another cable.
Just ordered a used Fascinate from Cowboom, and I've had nothing but trouble. It didn't come with the standard oem cable, so I've been trying to use old BB cables, to no avail! When I try to access mass storage, I hit enable on my phone, but the computer says USB not recognizes, or something along those lines. It charges fine with the cable, but can't access mass storage. How do I fix this?
Edit- tried with windows 7, 32/64.
I'm having the same prob with my husband fascinate (the pc recognizes mine with no prob)...I'm thinking there's something wrong with the micro port in the phone (it also got soaked in water overnight) but are you sure you have all of the right Samsung drivers installed on the PC? I know you can get them on droidstyles guide to rooting...that would be the easy solution...if you've tried that you may want to try different cables...although none of this worked for me it may for you...I'm now onto trying to replace the plug on the phone itself being i can see the corrosion in it...

Get this Samsung cord for $1.67: http://www.amazon.com/gp/offer-listing/B001XXUOQI/ref=dp_olp_new?ie=UTF8&condition=new
Then use that cord and tell us if it works. [Or you can try another micro USB that you have]
If it still doesn't work, and if it was originally purchased less than a year ago, Samsung will RMA it for free. Mine I got 11 months old, and would only charge, and not connect to the PC.
I had it sent back, they "fixed" it but it kept freezing every morning when I woke up [after sitting for a long time] so I sent it in again and they replaced the BGA or something and also the main board, and after that it worked fine.
First, i apologize if there is already a thread regarding this, but everything ive came across searching on google/xda has come to no avail.
i just got the i777, plugged it into my computer and nothing happens. on my phone it says "mtd connected" and charges.
ive turned on usb debugging, installed samsung kies, installed the drivers, tried the "dial *#7248#(or whatever it is), ive tried 3 different usb cables, all the usb ports on my laptop (brand new alienware), and also 2 other laptops. nothing works
my computer also makes the sound that its been connected. if i go into device manager it shows as Other devices > 7 CDC's with the yellow exclamation mark
if someone .could PLEASE help me it would be much obliged, all i want to do is start flashing again

Probably a bad usb connector on your phone. What rom are you currently on?
I was fearing this. Its all stock, not even rooted.
IF i have to get a new usb port, do i have to do any soldering?
When I had this problem I downloaded multiple different drivers and eventually found ones that worked . Try Google searching i777 usb drivers. I downloaded ones that worked from softpedia actually.

No soldering required. It's just a ribbon cable that connects to the main chip. Took me about an hour from start to finish, but i was being really careful.

He has said his computer recognizes the device, albeit it sees it as an unknown device. And it makes a sound when plugging it in. This tells me it's not a usb port problem but a driver problem. I have had this same problem. As I stated above. Even after installing kies it still didn't recognize it. I had to install the android sdk package, open the program and update, and then it still wouldn't recognize it. I had to download separate usb drivers for the phone as well. Who knows why, some computers or operating systems just have a harder time with the drivers. That's the problem in my opinion. Here's hoping it's not a usb port problem. Also this would prevent charging if it were a faulty usb port on the phone wouldn't it?

I wonder if the OP tried this on a computer with Windows XP. I've noticed Vista and 7 seem to have a hard time discovering/installing some usb devices. As for it not charging also..I think the pins inside the port are used separately for charging and connecting to pc.
My computer recognized my phone fine back when it was the Captivate, but it has a really hard time with my GS2. It often will say "invalid hardware id" or not show up at all. Usually it's fixed by swapping ports.
My i777 will not connect to my pc through usb, the pc doesnt even charge it!! The usb cord will charge when its plugged into a wall charger though. I know its not my cord because ive used different usb cords and they dont work. And its not my computer because I can connect other devices to it via usb. My phone is rooted and on stock Samsung jellybean firmware. Can some one please help me !
Did you even try to search? Plug your first sentence into the search all forums bar and see what comes up. There are so many threads on here about that problem. Give the search bar a try before creating a thread. That is on of the rules here.

Yes I did, I searched for a couple hours looking through threads even went to different websites. None of the solutions worked so I created a thread hoping someone could give me an answer as to what is going on with my phone
By your PC not charging your phone it is very hard to tell. Lets start with the basics. You have tried different usb ports on the computer. You have turned on USB debugging on your phone. You have tried different USB cables. You have uninstalled and re-installed kies on you computer. You have done what you could to clean the usb port on your phone. You have tried to connect your phone to the pc in download mode. That about exhausts my limited knowledge. Sounds like you have been pretty busy over the past couple of hours to get all that done. I am not sure what to tell you besides it sounds to me like your phones usb port is toast. Maybe you can do some searching and see if you can find some one that can repair that bad boy for you.

Alright so I know what caused this problem, I used framaroot to root my phone then unistalled the app. When I uninstalled the app thats when I started having this problem. So im going to see if the dev of framaroot can help me out
