I can't get my phone detected via usb from any device or computer. Weather in android, recovery or bootloader. The phone still charges fine however. The phone also will think there is a USB cable plugged into it when there isn't.
I don't know what to do to fix this, or if its even fixable. I've tried four computers and 3 different cables, along with removing and installing the drivers multiple times. Changing roms/kernels doesn't fix it, obviously its an issue beyond that since fastboot won't detect USB either.
Any help would be appreciated!
Get some canned air and blow it into the slot for a while. It sounds like there may be something conductive stuck in there. Maybe get a magnifying glass and look in there to see if you can see anything.
Tried blowing with compressed air and got my eyes all up inside there and nothing
Any luck with this issue? I'm experiencing the same problem
sounds like a piece got loose inside the phone and only the power parts of the usb slot are still attached which is weird im guessing just hardware failure.

Is the phone showing up in device manager on the computer?

No it's not..
Yeah that sound like hardware issue for sure.

Damn, was hoping i bricked the USB like I've read about the HTC Desire, was hoping to somehow reload/reinstall the driver.. I guess off to HTC to see what they can do.

how do i fix the "Usb not recognize"
Did you install the Samsung drivers?
nope, but i know this is a problem with rom? cause yesterday it's fine but when i reinstall bionix usb can't recognize now... what should i do?

FIXED.
But CD ROM on Vibrant?? how to remove this?
USB not recognized - how I fixed my problem
I've been beating my head over this for about a week. I've installed/uninstalled drivers a dozen times, cleaned the registry, deleted application data, etc.
The puzzling thing for me was that it had worked reliably for me at one time, and I had gotten it to work on a couple of other occasions through all of the gyrations above. The phone also works fine on another computer. WTF?
After a fair amount of googling I pieced together enough to start questioning the integrity of the USB connection. Some people said using a different cable worked, others said plugging into a different USB port worked.
What worked for me was moving the USB cable from the front panel connector on the computer to a back panel connector (soldered directly to the mother board). As I said before, others have said changing cables worked for them.
I suspect that the phone's USB signal integrity is marginal (possibly bad impedance matching). Add to that questionable quality control on cabling inside and outside the computer.
Anyway, try connecting to a different port on the computer and/or changing your usb cable.

Fix USB Device Not Recognized
I went through the biggest search to try and fix this issue. Connected my Vibrant on different computers(different OS's) and found not a single solution along with drivers. Tried different usb cables and nothing but the same error. Look inside the usb port of the phone.....ah ha!!! small amount of lint managed its way in there and stuck to the pins. I was able to charge so it never occurred to me up until last night when I wanted to put in a new ROM. I used a thumb tack and carefully cleaned the port( REMOVE THE BATTERY FROM THE PHONE BEFORE DOING THIS!!!)
Also make sure the cable didn't suck up some of the lint too. this happened to me too.
Good luck
So, I'm having an issue where my PC can't see my phone with PC Companion open or closed, Phone on, off, or in recovery, with 2 different cables, and with USB debugging on or off.
Does anyone have any suggestions? Or do I just have broken pins on my USB port? cause I can still charge via USB.
Also, I'm on the wrong kernel so I can't access ClockWorkMod and update the ROM
I'm using an old version of this ROM (last updated mid-October, 2011)
tl;dr: PC can't see phone when plugged in, tried common sense options, what do?
More info: I did some research and found others saying they got a message saying "Unrecognized hardware" I don't even get that, nothing happens at all when I plug it in, although the phone does charge.
I have also tried 2 different PC's (both W7) and all the USB ports on both.
I would guess that the pins are busted in your phone. There are a few people with this hardware issue from my reading of the forums so this is not uncommon.
I'm in the same spot, I haven't been able to USB connect my X10 for months. The repair guy told me it wasn't fixable, so I'm stuck with locked bootloader and xRecovery flashing only.
Sent from my X10 using XDA App
That's about what I found too. Someone said to try rubbing alcohol and a q-tip or blow in it (a-la NES style) but I doubt that will work. At least you can flash with xRecovery though, I screwed something up and can't access it anymore.

Try that.. hope it helps.
My SGS2 keeps disconnecting and reconnecting the usb with my computer. This is hapenning for quite a long time now.
I keep hearing the windows connect/disconnect usb sound when my phone is plugged in, making it unable to recognize the device.
Today, it finally didn't had this problem for a while, so I took my chance to get back to stock ROM (because I need to send my phone to Samsung for camera problems). So I flashed stock ROM with ODIN, but I encoutered a problem: it didn't get further than the boot animation.
When I tried to reflash, ODIN didn't recognize my phone anymore, just like before. When I plug in my SGS2 to my computer while on download mode, it just keeps reconecting the USB, so the device can't be installed.
Tried a different computer. It kept being connected, but that comp sucks and it couldn't recognize my phone at all. My own computer also has problems recognizing the SGS2, but also has the problem that it can't stay connected.
Things to know:
- Other usb devices do stay connected, it's just for my sgs2
- I've tried different USB hubs etc., reinstalling Kies, uninstalling drivers.
- It does keep charging the phone, even when the computer makes the disconnect sound. That makes it even weirder!
Basically I'm seriously out of clues how to revive my phone
I don't want to send it to Samsung, scared of losing warranty.
You guys are my last hope!
to start the ball rolling, YOU SHOULDNT BE connecting sgs2 to a HUB, thats probably the fault, second, have you tried a different usb lead or a different computer with the same lead to either verify if its the phone or lead at fault??
No one on here can answer your question because it sounds like a hardware issue, wire or hub or charger port, but it is an elimination process and only you can do that.
If you try everything and still get no joy, restore your pc to an earlier point, uninstall the samsung drivers and re-install them etc etc.
I very much doubt its a software problem tho, looking at what you tried already, lots of people use hubs, if youre flashing roms and your connected to a hub then ya play a dangerous game and risk soft bricking your phone, most of the time odin wont recognise your phone through a hub, same if ya usb lead is too long, itll charge but no data. always connect it directly to the pc usb 2 port.

Ow, I think I used the wrong word. I meant to say port instead of hub.. Translation fail there. So that's not the problem, I've put the cable directly into the USB port.
I think you are right about the hardware problem. I'm just not sure where the problem is. I only have one cable, so I can't test that atm. But like I said, the connection problem does NOT occur on another computer. It keeps the device connected (as an unknown device though).
So it's weird: it looks like a SGS2 hardware problem, but on the same time it has a different problem on a different computer. It's really confusing...
Thanks for the quick reply by the way

Then please explain me how I could ever do that when there is no working ROM on my phone. I'm stuck on the 'restore with Kies' screen, like I told in my post (yes, still). And how it will ever work with ODIN? It won't...
Now not any computer is connecting with my sgs2. It just doesn't show anything (not even unknown device). I'm going to try to buy a new cable. Is it needed to buy a Samsung cable? Because it's harder to find than just a regular usb to micro usb cable (and more expensive ). This is my last hope. When it's not working, I need to send it to Samsung.

You need to replace your usb board within your phone. New part can be found on ebay for around $10. It's a really simple task replacing it. No soldering or anything.
It's been well documented on these boards.

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.
So I was just going to change ROMs, and I realized that my DNA won't connect to a PC over USB anymore. I always plug it in at work via USB to a laptop to charge, and it would normally open the autostart/autorun window, which I would always notice because I'll switch computers often. Last week the autostart dialog stopped opening, but I was distracted with work being busy and it just went to the back of my mind.
Until now.
I've checked all the normal trivial stuff... trying different cables, using different USB ports, and obviously different PCs. It also won't be detected by ADB. Yes, developer options are enabled, yes USB debugging is enabled. It sounds to me like its the port on the phone, so then I'm screwed, but I was just wondering if anyone knows any tricks I can try.
Are you running a custom rom? Go to settings>storage>storage settings>USB computer connection and make sure the connect as Media device (MTP) is checked. Same thing happened to me and some how this setting was unchecked

You going to laugh at me but download PDAnet and it will redownload the correct drivers.

Have you found a solution for this? I am in the exact same situation with no solutions working for me. I tried PDAnet and many other things. The device is unrecognized by my computer completely not even showing up in the device manager. This likely is a hardware issue, but I'm rooted with no way to return to stock because I can't connect to my computer which makes me unable to use my warranty for repair. This is a really unfortunate pickle as I'm not sure if I can even do anything at this point. I have found online that people with a hardware issue with connecting to their computers also had the slow charge notification when charging either through the computer or the power adapter. Mine does not display slow charge which gives me some hope that it is somehow a driver issue. Do you get the slow charge notification at all?
EDIT: It's a hardware issue for me. Noticed my charger is sticking slightly more out than usual, and it just can't get the right connection

Hey guys, just figured I'd follow up. Sorry for the delay, XDA email notifications somehow ended up in my spam folder.
Anyway, for me it just turned out to be that all the cables I tried were bad. Pretty low odds, I'm actually surprised both my cable at home and the one at work were all bad. Sure enough I tried it with a coworker's cable and it worked fine.
