HELP: USB Debug Mode not working Anymore

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

since you have w8 you will face connectivity issues
search on how to set up adb/fastboot on w8 here in xda
also check in youtube

Did you enable usb debugging from the phone settings? And is your fastboot folder complete with all the utilities?

The problem for me was unknown device under Win8.1

USB debugging shouldn't affect fastboot status. Only ADB.
Happy to help.

USB Debbuging should be enabled, I had the same issue with Win8.1 and use USB2.0 ports only, not USB3.0 and better not even a USB2.0 external Hub device.

Dear Friends,
My Le1s now facing a problem with the USB connection. It does not showing USB connected notification. And PC shows that USB device is malfunctioning.
I'm planning to flash a new rom. But due to this problem I can't do anything. Please help.

Is it charging while connected to pc ??
If answer is yes..
Then ur usb type C cable is problem
Buy another one to make sure the problem...
If answer is no..
Then try the services of local authorised serivce center..
Or flash same rom..

Question fastboot and adb doesn't recognize devicer

i already updated both adb devices and qualcom,
i downloaded most updated fastboot
it doesn't show more than charging - like i can't access the storage.
oem unlocking it ticked, usb debugging is ticked.
only one thing could be the cable but i've it a week ago..

you approved the usb authorization prompt on the phone when you connected your device to the pc?

Device is stuck in EDB mode
Fastboot will pickup
ADB & charge mode fail
fix
Removing the back cover disconnecting the battery and reconnecting it
