Try to reboot it with ADB 'adb reboot' if even that doesn't work there might be somethink broken on your USB connection (PC, kabel or USB connector of your OB).
If you don't have ADB get it from here: forum.xda-developers.com/showthread.php?t=2105931
This is just a very basic test but the connection with ADB often works even if anything else doesn't.

****. now the phone wont start. not charging... and power button not working

found out that it was hardware issue. when i press at the back of the usb port it charges and the phone connects. how to fix this?

Please help...big problem....

Big problem. Suddenly my phone will not turn on. Sits at the white Galaxy S GT-I9000 screen and does not boot. When I put it into download mode and plug it into computer, its suddenly saying "USB Device Not Recognized".
What do I do? PC won't recognize it, it wont boot. can't flash it.....I'm freaking out here...
Did you flash anything to it or root it?

Hi Rick. Try to re-install samsung usb drivers. during this time, take out the battery from the phone. once finished installing the drivers, put back the battery into the phone. Go into downloading mode. Fire up odin, put in the necessary firmwares + pit files. Once done, then CONNECT your phone to the usb port of your computer.
Hope it's okay.
Edit: Let's hope that it is the computer usb drivers are corrupted. Alterntively, if you still can't do it, try it on another pc.
Nope. I was rebooting it to flash XXJPC to it, but couldnt do so because it was saying that USB message and wouldnt detect it. So I went into recovery, did a factory reset, and now it wont boot.
Another computer does the same thing *tears*
*BUMP*
Lets try a different route. I will pay a generous sum of money to anyone who offers to and does manage to fix this for me?
rick, looking at this, if your usb is not recognised, it is either the pc or the phone usb port might be damaged.
if it is a hardware issue, then use the bounty to get it fix.
I was at that same point with my vibrant. After failed attempts of getting into download mode using buttons, here's what I did.
Download and install samsung usb drivers and android sdk.
Plug into the computer and use adb to get into download mode (adb reboot download).
Then flash with odin.
Doing that worked for me when nothing else would. Try it ?

I can get into download mode just fine.....my pc just doesnt recognize the usb device. tried 3 differente pc's, 2 running win7 and one running xp.
Did you install usb drivers on each of the machines?

I installed the samsung USB driver executable. and I also tried to use those drivers that it installs to manually update the "unknown USB device" in device manager, but they won't take.
Try uninstalling all drivers, then stick a MicroSD in your phone before plugging it into the usb.
Assuming you have Samsung Kies in your PC, try to upgrade it at 1.5.1.10074_45.
How long do you wait the boot?? The first boot after flash is very long, wait at least 5 minutes with flashing "S".
I did not just flash anything. My phone got really hot and laggy (as I was using it while charging it via USB port) and so I rebooted phone in an attempt to resolve the lag. when I did, it would not go past the WHITE Samsung Galaxy S I9000 screen, does not get to the flashing S screen.

if i understood you correctly, you have two separate problems:
a) your phone does not boot up
b) your phone is not recognized by any computer when plugged in
could be a coincidence, but probably is not. i'm guessing your bootloader got screwed up somehow. if it is a coincidence, it could be that your usb port on the phone is effed, or your usb cable is dead. try first using a different cable and see if your phone can be recognized by any computer. perhaps then you can go into download mode and reflash.
also, have a look at this post, might help you (although, if your usb is effed, there's not much point in trying any solution that involves your phone being connected to a computer): http://androidforums.com/780720-post3.html
EDIT: also, have your tried the obvious stuff, like pulling battery?
I ve seen many threads with the white screen problem ... it has in most cases been the drivers ... you desinstall all drivers from pc using Kies option for resinstall the drivers ... then you pull the battery off few sec (give it a min or two) then you get to download mode and you flash the beast ... dont connect your phone before launching odin or else it will not be recognized ...
for the few other people who didn't manage to fix it ... it was a hardware failure
That post you linked, is worth a try. But its for a motorola.....Where do I get my SGS bootloader to use instead?
ohh you were implying to try to use the motorola usb drivers?

I never said anything about a white screen. and I am not uneducated on flashing SGS, or using Odin. Far from it. My phone was first showing USB symbol when it wasnt plugged into USB port, then phone started running really hot while charging and got really bloated like it was overheating. So I rebooted and its now force closing at the first boot animation. I can get into download mode and recovery, but will not recognize in any of the 3 computers all running different versions of windows on them, with either of my USB cables that I tried.

Make sure the cable is properly connected. Check for dust that might prevent it going in properly. Try a different cable. What OS are you using? I found where bootloader is dmg or incomplete Windows fails to detect it. Linux on the other hand detects it. Can't use it but you can detect it.
Can you connect to SW Update Mode? Battery out and plug into PC while holding vol up button.
If nothing works try taking it into the shop.

You can root your phone from there. If you have SW Update. I recommend taking it into the shop if you are still under warranty, If you don't have warranty then you can go ahead and root. Just install a patched bin and fls with Smart Flash Tool. It's one of the stickies (How to unbrick, I think)
hi
new to Android nation
I have the same issue when connecting to USB...
And I managed to flash with custom firmware (latest ZEUS version) and I rooted but the issue with USB connection is still there...
Anyway, I wiil try connecting it to Linux to check if that would work with USB connecting
UPDATE:
OK after some digging, I managed to (at least temporally) solve the issue... After fresh installing official 2.3.4 firmware I booted to recovery and from there formatted the system folder and then installed Zeus v7 firmware... anyway, USB connection and charging indicator work fine at first booting to system... As soon as I reboot the OS USB connection (and charging) get unstable, and after third reboot it completely goes away and the device does not recognize anything: if I connect USB cable it does not show any sing (charging indicator does not show battery charging, nor the device offers me to connect in mass storage, windows recognizes only modem but not the USB storage) and when I connect charger, battery indicator does not flash as charging... Battery monitor tool shows that "battery is discharging" even though the battery capacity seems to increase (according to growing percentage of battery capacity)... Is there a some kind of USB server... I am a total noob to Androiid OS (used to be Symibian from its beggining )so I hope you won`t mind if I used wrong terms in my explanation/comment...
I hope my explanation is not confusing
Cheers
UPDATE 2:
After installing Zeus v7.01 update, battery charging recognition got fixed using both USB cable and wall charger...
Anyway, USB recognition by PC problem still exists... But when in recovery mode I can successfully mount SD card to PC in Mass storage mode...
Will keep you updated... :victory:

Any help of terminal command in TWRP?
yes you can try pulling the files if you can go to TWRP...

Is it really? Well the odds of only data transfer terminals and not charging terminal being damaged is very low. Does your computer make notification sound when you plug in your switched off phone to PC USB port. If it does then I think it's drivers problem instead. Try Universal Adb Driver. If the port is really damaged then get it replaced or replace yourself(if you can) and then try..

The USB port is the hub. If it's damaged then there's no way. I am sorry to say this but it seems like the damage is in the circuit board and only service centers are able to recover this.

Device unconnectable to any PC

Hi,
my problem is, that my P9 canĀ“t connect to any PC via USB. I tried 3 PCs and 3 USB cables. Nothing works, my device also not listed in the Device-Manager. No PC is recognizing a new device but the phone is charging.
I changed the USB-Mode via *#*#2846579#*#* but none of them gives me a connection. Also in TWRP or Fastboot no connection.
Do you have any Ideas? Maybe the connection to the Mainboard is dead?
Regards,
Kaese

Not this tool but ADB commands and nothing works because the PC can't detect the phone.
I had this with a P6. The USB connection was stuffed. It would let me charge the phone but nothing else. Send it in for repair.

Cannot connect One Plus 3t to PC, not showing up on device manager

So basically I searched everywhere and found many people with this issue.
I tried everything everyone said.
From installing the drivers, to turning on developer mode.
Also fastboot mode is not working.
I hope my is not a hardware issue. I tried a new cable with the same results.
Anything else I can try?
I have been using FTP to transfer files but I want to root my phone and I can't.

The last time I read about someone having a similar problem it was resolved by using an original cable. But I can't find the thread where this was discussed.

Just to rule it out, after you connect your cable are you seeing the Notification with USB options and have you selected 'Data Transfer', (or whatever it's called)?
If you are seeing the Notification and the PC still can't see the device, uninstall whatever Drivers and ADB packages you currently have installed. Download the ADB package from Google and, when prompted, say 'yes' to installing the Drivers.
Make sure you try all your available USB ports.
Are there any Yellow exclaimation marks in Device Manager? Do you have the most recent Motherboard drivers from your Manufacturers website?

No the notification doesn't show up and my device doesn't show up on device manager.

If you have a can of compressed air, try blowing out the USB port. There may be debris up there. It does sound like a Hardware problem. You really need to try it on another PC to know for sure.
You don't have any issues when charging?

The phones charges perfectly, I already cleaned out the port.
So, I still have this issue and I wasn't able to solve it. Pretty much the phone only charges, doesn't get recognized by any computer. I also tried my laptop and same thing happens. How do I find out if it's a hardware issue?
Is there any way to save the phone?

You can connect your PC to your phone without cables using ADB over wifi provided your phone is rooted and on the same wifi network as your PC.
I know this won't solve your hardware problem but it does allow you to move files between your PC and your phone using ADB.
Note that this doesn't work in recovery or fastboot modes.
Here's how:
On the phone using Terminal
su
setprop service.adb.tcp.port 5555
stop adbd
start adbd
On the PC in a command terminal
adb connect xxx.xxx.xxx.xxx:5555
...
adb disconnect xxx.xxx.xxx.xxx:5555
where xxx.xxx.xxx.xxx is the phone's IP address
To set the phone back to normal (optional)
On the phone
su
setprop service.adb.tcp.port -1
stop adbd
start adbd

You could also try using flash drive via OTG. This won't help you connect to PC/Laptop in any way, but could at least progress a bit that the phone hardware is okay for data part.
This problem start again , fortunelly im in nougat so if i go to dev options and change the usb charging to mtp his comes to charging again . I think this is the problem , the phone dont comes to mtp so dont "have" a device in windows to connect , with this im unable to make root and do anything in fastboot because my phone lock to usb only for charge
