I'm unaware of any tablet vendor that has drivers for a chromebook. Not unless there is a no name vendor out there.
Most only have drivers for Windows/Mac. Linux (thankfully) has them built into the kernel on most distros and while ChromeOS is using the Linux kernel, it doesn't have that in there as far as I know.
I guess you could open up the terminal and do
and see if anything shows up.
Typically, if the driver is installed, that command would display a manual of usage of the cli version of the driver.
At one time Wacom was looking at a solution, but I don't know how far that's come or if it's no longer viable.
