ioctl hangs #40

Hi, Daniel! I am trying to use your driver. I've changed nothing in your code and configs. I run

_$ LD_LIBRARYPATH=pwd/user user/mcp2210-util set config 32

But it hangs in mcp2210_ioctl(). I even have to reboot in the end. Have you ever faced this problem? Could you help me to find a reason?

UPD: The case is changed. The reason of hanging was I messed up MOSI and MISO. But now I get ioctl failed: Operation not permitted
