That is a really usefull addition to be able to use GPIB with Linux. Thank you! Unfortunately the pyVISA community did not manage to add this GPIB adapter to its library. There is an open issue since more than 3 years, so I guess it makes sence to add it to BASIL.
After a quick look over your code I think it can be slightly simplified.

As I see it the only difference to the already existing VISA implementation is the query command. So one could simplify this module to:
class PrologixVisa(Visa):
def query(self, data):
self._resource.write("++auto 0")
self._resource.write(data)
return self._resource.query("++read eoi")and it would do the same, no?
I am not sure if the write and read commands also need changes. Did you check?

The identifier does not have to be fully matched. So sometimes it is better to not specify minor firmware versions for compatibility. I guess HEWLETT-PACKARD,E3632A could be enough here?
