The ideal is for both the host and the device at either end of a USB 
cable to be "standards compliant":

https://www.usb.org/


This implies a complete and correct USB hardware/ firmware/ software 
protocol stack on both of them.


I try to buy computers, motherboards, add-on cards, etc., with Intel 
chips because Intel releases open-source reference device driver source 
code for some portion of their products.  Linux, Debian, FreeBSD, and 
other FOSS projects use and include this code (in source and/or binary 
form).  This gives me the best chance of a positive OOTB experience with 
those FOSS operating systems/ distributions:

https://software.intel.com/en-us/open-source


AFAIK there are no commercial off the shelf (COTS) USB-SATA docks with 
FOSS hardware (device), firmware (device), or software (device or host). 
  (If somebody knows of any examples, please post the URL's.)


But, it might be possible to build your own using a FOSS operating 
system/ distribution and a single-board computer with a USB device port 
and a SATA host port:
