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.

Thanks.

Hi, i have the same problem here.
I cant connect to PC but charging phone is normal.
I have checked USB drivers everithing seems to be ok.
I have instaled MiPhoneAssistant.
Maybe reseting usb hubs will help??? Sometimes after pc goes to sleep windows forget usb device.
MIUI global 9.6 stable 9.6.2.0
I have solved an issue.
Go on your phone Developer option and change to PTP (pcture transfer)
Connect to PC
Drivers should be instaled corectly
After that, everithyng works fine with every USB mod selected
