Are CP210x devices supported in my version of Linux?
CP210x drivers are bundled with kernels v2.6 and later. To see specifically if your kernel has support for CP210x devices, you can use the command 'sudo lsmod' to see a list of installed modules. CP210x should be in this list, if it is supported.
Starting in kernel v4.10, a GPIO API was added to support GPIO reads and writes.
Latest version of the driver included in the kernel can be found here:
