(there was a failure while reading analog voltage from a pin board is shut down and pluged out the ST-link connection.10s of secs it wouldnt boot and after a waiting and plug the power it booted and i can program it without any problem but). when i connect the usb user/micro usb(other usb/Debug port is offcource connected to power the board), it doesnt appear in the device manager so i cant see in the port and no usb connection sound is heard, but usb LD5 led is on.
PS: While failure was occured, usb user port wasn't connected to the pc only debug port was connected.
Thank you.
