This happens today as i am debugging a little program of mine. Suddenly, the device stops from being recognized on both macs and Windows. At first i thought the mini usb connector was faulty however, i connected the cable and it shows that it's charging. However, when i do ADB devices.. still no devices found.
Can anyone provide a solution to this?
Tried enabling usb mode on and off, restart PC and mac. nothing works.
Thanks.
What rom use....? Stock or dev. ????
If your dev. rom ....you should off the debugging

Have the usb drivers in windows and it was working. Now it won't turn USB debugging on. I tried on Linux Ubuntu also but no luck. Any idea? I am on custom recovery with stock rom if that helps.
edit: so it appears that that the debugging does work when using adb. adb devices recognizes my s3. But nothing noted in the notification bar when attached via usb, only connected as media device. When I switch to CM10 from stock, the debugging notification appears. Is this a samsung thing? Any thought would be appreciated.
Bump - Had this same issue. Wasted about 2 hours last night trying to figure out how to get USB debugging to turn on so I could start the root/unlock process. Turns out, debugging was on, but the phone never notified me. I'm on a new rom now and it does correctly notify me with debugging on.
Ics says nothing. JB says it charging lol.
With my usb data. It was connected succefully before. So i am clue less
Are you trying to connect to transfer files, sync outlook or issue ADB or APX commands?
Does your computer play the new hardware sound?
What OS is your computer running?
Do you have USB Debugging checked?
Have you tried another USB port on your computer?
Also, many of the JB ROMs show a charging indicator via USB even if it is not really charging.

Done that but not luck
purely software problem try and same with another usb port
I recently rooted my s8+. Now when I connect it to my PC (or even my wife's PC), I get the following on my phone, "Attention: the connected device is unable to access data on this device. Please disconnect the USB cable and try again". I'm using the USB cable that came with my phone and the issue is happeing on 2 different PC's. I have USB debugging checked and set to MTP.
in settings, Switch on Developers options in configuratien. Then there is a USB modus setting. Set it to Charging rather then MTP Transfer.
try another USB cable and update the drivers in device manager.

Ok, I've tried your suggestions but the problem still persists. What's worse, I unrooted the phone and did a factory reset and it STILL is unable to access the data on the device.
Need help. I was using Miracle Box to flash stock ROM, I don't know how but the phone (Micromax E453) is bricked now. I tried to start phone in Meta Mode (swiched off phone connected to PC by holding volume up button), it worked once, then following some tutorials I uninstalled (and checked, Delete the driver software for this device) MTK USB COM driver under port. Since then phone is not turning on and PC is not recognizing the device. Tired changing the USB cable and even tried it on another laptop, but no go. Kindly share what else I can try. PC has Windows 10 64 bit and MTK preloader vcom driver always has yellow exclamation mark (always installs with error code 10). I have disabled driver signature verificiation.

Did you have USB debugging enabled in the device's system settings before it got bricked? If not, you might not get it to connect via USB and be recognized.

Thank you for your response. Yes, USB debugging was enabled before it got bricked. I was able to successfully see my device when I ran adb -devices command. I was also able to run fastboot commands. Now its completely dead.
