It is extremely unlikely that a single device support would have been 
removed within a single major branch like 7.x. It has never happened 
before. If it works for you in 7.0 it will continue to do so at least as 
good in 7.2.

But there is a tiny possibility, with esoteric hardware, that a bug that 
was not fatal in a previous version becomes fatal in the new one. This 
is very rare but if you are very concerned you can check this by 
downloading a live cd (e.g., 
booting it and testing a little.
