I have a stm32 board which have stlink with it. I installed the stlink and all the necessary udev rules are there. If enumerated properly it will create a serial device /dev/ttyACMx and will also show a fat partition.
When the board is connected and i restart the computer it works fine, serial port is there. But when the computer is running, i remove and insert again the usb cable it is not recognised. I get the following error in dmesg

I got it working. Actually the cable was faulty. I tried with other cable and it worked fine. But strange thing is that after usb reset old cable works fine.
