Subject: pr_info in driver question

Hi everyone,
My name is Andrew.
Recently, I went through the Linux Foundations intro to kernel development course. As part of the course, it gets us to put a print statement inside of the uvcvideo driver, recompile the kernel and then load the module and check dmesg for the print statement.
After several attempts, I was unable to find this print statement inside of dmesg. I know that the modified drier was compiling successfully and my custom kernel was indeed installed but no idea about this pr_info statement.
I tried this in Ubuntu and Fedora inside of virtualbox. Not sure if that would make any difference.
Thanks,
Andrew.
