Here we can see the /lib/modules/2.6.32-431.el6.i686/kernel/drivers/net/wireless/

a directory is installed under the 8192cu.ko the kernel module

load the module to drive the hardware, you can use the command Insmod "full path, cannot resolve dependencies"

                                                                  modprobe 

Here we use modprobe , and use Lsmod after filtering, we found 8192CU
