Hi,

I just encounter a problem following the instruction in the above link:

aging:/myspace/workspace/ch341/CH341SER_LINUX$ sudo make load
modprobe usbserial
insmod ch34x.ko
insmod: ERROR: could not insert module ch34x.ko: Required key not available
Makefile:9: recipe for target 'load' failed
make: *** [load] Error 1

After make, I will fails to load the module.

Please suggest how to fix
