If anyone needs the Cree device (Sic?C4D20120A) I've put an updated .rect file in the Files/support_uploads folder.
To install it, you need to download to the area where PSUD2 stores rectifier files. On English language machines this will be:
[Windows]? ?C:\Users\<user name>\AppData\Roaming\psud\rectifiers
[MacOS Finder]? ?Documents -> psud -> rectifiers
[MacOS Terminal]? ?~/Documents/psud/rectifiers
