Uninstall the USB whilethe PC is in normal mode. (from the control panel-Device manager). This I was able to do.
Remove the stick
Reboot the PC into safe mode
Insert USB stick
It was detected fine. I was able to open the stick and use it as intended.
Eject the stick (still in safe mode)
Restart PC in normal
Put in stick.
Now its fixed.
thanks for help… it will help me this way…
