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.

Ok.
So at some point I soft bricked my phone and I got the Phone -- ! -- Computer screen.
Managed to get it back into download mode, and then unbricked it by getting it flashed to EB01 as instructed in this thread
http://forum.xda-developers.com/showthread.php?t=1026746
So now I have EB01, which is working, however there is a new problem.
When I try to plug the phone into a computer, it is not recognized (Says the device has malfunctioned).
I have tried 3 different computers. I made sure I used the cable that came with the phone.
I brought it into the Verizon store, and they were unable to get any of their computers to recognize the phone either (we tried a few other cables there as well)
This is both in download mode and within the OS itself.
They told me to try downloading Vcast however that didn't work either.
So now I'm wondering if there is something I can do to get it to recognize it properly again.
Has anyone run into this situation before and managed to fix it?
I did twice have the phone plugged in via usb to my car, and walked out the car (was talking on the phone), and the USB yanked out, so that could have potentially damaged it (though it still charges, so I don't know)
Yanking it out could have very well done it. Only thing I would suggest is reformatting the drivers and attempting again this time leaving it plugged in and rebooting the computer. If that doesn't work, replacement time.
Do you have "usb debugging" turned on?
Did you activate the connection from the phone after connecting to computer? (mine shows a green screen with a button to activate the connection for mass storage)
beyond that... idk.
redownload the samsung drivers
based on the fact that so many PC's have been unable to connect and the info on yanking the USB charger in the car (I think we have all likely done that - though for me it has happened at work with the laptop<->network cable...) you may have damaged the plug/receptor (not sure what would be proper...).
I would do a visual inspection for kicks, though I am sure there could be damage you cannot see.
I believe that these USB connections are a minimum of 4 conductors (some devices are more proprietary and use more pins to ensure you are using an official cable so they can get you to buy more of their stuff - though some of those pins are not actually wired through the cable, but rather short to each other...). If you damaged only one, that could likely be the reason that you can get a charge but no data comm - and since it seems likely that one of the two data pins would be tx and the other rx, then I could see why teh PC would report the device had malfunctioned...
I am guessing here - logic, please don't fail me...
when i plug my phone into my computer, nothing. the phone pops up the notification to allow mass storage, but when i enable it the computer never shows the phone. i've messed back and forth with usb debugging, still nothing. is this sometihgn stupid i'm doing or what? I've even flashed a couple roms andstill nothing. help please?
its most likely the usb cable try a differnt one
that's what i thought, i tried two different cables (all i have are 2) and neither will work. Note, that when i use these two cables with the wall jack to charge they work.
do you have another computer? try it with another computer
or try a different usb port! or try installing mini kies that sometimes fixes the problems
Try rebooting and turning usb debugging off. Then plug up to pc (see if it installs drivers) then unplug, turn usb debugging back on and then plug up again. Should work after that.
OP-
A few days ago I posted regarding my similar issue (2-3 pages back).
I have still not resolved my problem, but that thread may give you an idea about troubleshooting.
Let me know if you figure it out.
For me, its most likely a phone issue & not a cpu problem.
I'm going to try cleaning my port with isopropyl alcohol later this afternoon.
You also might want to look at Callip's advice in the "PLEASE HELP" thread on this page.
wow, thanks for all the responses guys, i'll get to all this tomorrow some time and i will post my results.
The other day I plugged my x10 mini pro, (u20i) into my laptop to transfer some pictures over and the "USB Connected" flashed on and off in the notification bar, since then, the mini usb on the u20i has not worked for anything other than charging, I'm assuming it's a hardware failure but am hoping theres an easy fix for this as I now have no access to flashmode, adb, or data transfer, charging still works fine, I've tried wiping data and doing a factory reset and a complete reinstalltion of the rom but the problem persists, I'm running minicm7 2.2.0 rom using naa 11 kernel, PC companion also doesn't detect it and windows itself says that the usb device has malfunctioned and can't be detected, I'm gonna try accessing the bootloader through terminal emulator and flashing the kernel again incase something somehow got corrupted and will post the results, but I'm guessing it won't get detected anyways.
Anyone who has experienced this, or has any ideas are welcome, as without adb and flashmode I'm kinda stuck, thanks in advance.
Edit: Tried accessing flashmode (bootloader) through the terminal emulator and the phone realizes the usb is in and stays in flashmode (screen off, Green led lit) like it should but the pc still doesn't recognize it. Everything else I plug in to the pc's usb ports work so it's not the pc either.
Also I restored a backup where I know the usb was working and stil get the same results
Tried lots of different cables including the one that came with the phone, still no luck
I had something similar with my X10 Mini Pro. The USB connection would only work if I had the cable in just the right angle.
Unfortunately, it's a common issue with the design of USB ports. Repeated plugging and unplugging can lead to bits being bent. I had a company laptop that eventually only had one of the four USB ports working.
What I ended up doing with the phone was getting a very short cable (about two inches) and hanging the phone from it. I've got a tower PC and this ensured a connection every time.

my mini has a similar issue, holding the cable does the trick
for charging, i need to place the phone at the border of a table, the cable being in the air...
only way left to charge everyday

Thanks for the replies guys, I have the same problem with charging, cable needs to be at the right angle to work, but it won't work with the data connection.
again, thanks for the replies
Typed on my mimmi using naa kernel and rom
Yes, Finally got it working, after hours of fiddling,prodding and poking I finally got the pc to detect it, just had to get the cable in at the right angle, I though I'd shorted something on the main board and could never use it again, cm9 here I come
My problem is that I cannot connect my Galaxy S II to computer. When I try to connect it only says "unknown device". I have tried with newest Kies and without Kies. With multiple computers with Vista and Windows 7 32bit. Also downloaded Samsung Galaxy S drivers manually from web but with no avail. And I have tried with Usb-debugging on and without it. I also tested USB-mass storage setting but it does nothing. Computer also says "unknown device" when I try to connect phone while in download mode.
The charging works btw.
When I connect the cable my phone just makes the normal sound but the mass storage android man newer appears to top tray. I have also made factory reset and cache delete from recovery but with no luck.
I would like to flash different rom with Odin but I cannot do that when the connection is not working. My current rom is official XXLPQ ics. The usb cable isn't the problem because I have tried with different cables which work normally with other phones.
Is the warranty repair only solution? Really wouldn't want to be without my Galaxy during the repair time.
Sounds like it's going to need a check over, if it wasn't for the fact you have tried multiple computers AND leads, as I had a similar problem but found it was down to my PC needing a fresh install.
Unless others with similar experiences have advice it doesn't sound good, as though pins 2, 3, or 4 have problems maybe, or that the board within the phone has bent up or down through rough handling/tug on the cable.
When did it start happening? I had a fright by tripping over the phone while plugged in, and ripped the plug out while launching the phone across the room. It broke the charger and thought I'd killed the port on the phone, but found if I propped the plug up and put weight on the phone it would connect, like this...

Might work if the board has got a whack like mine did.

As I mentioned earlier I have tried all that.
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

Android Sync manager Wifi is the answer you're looking for ^^
no more plugging in this... mounting that...
NB, has a pc side component

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.
