Newer MacOS USB driver

[vostok92]

Links to USB driver(SiLabs CP2104 Driver) for MacOS is too old (v4.x.14 - Nov. 3, 2016).

There is newer version of the driver (v6.0 - Dec, 18, 2020) on SiLabs site, and it supports macOS Big Sur.

Hi, Thanks for your concern.
We want to change the version of the new driver but we still need to do some testing to figure out whenever the new driver damage legacy support in older systems. Once we confirm it works on all older systems, we will update the driver.**
