Answer : my laptop refuse connecting to my flash card

What do you mean by "flash card"?
- USB stick
- EEPROM programmer
- Remote cable to digital camera to blink flash

Post error messages from "dmesg" - impossible to sort out without them.
Update your CentOS and post output of uname -a afterwards.
