I could be wrong but I don't believe this is necessary unless the OP has
actually manually configured each of these to be enabled after they are
installed with 'setup.exe'. Although both have a "preremove" script to
remove the enabled drivers on uninstall via 'setup.exe', neither has a
postinstall script which would introduce the drivers to Windows. So AFAICT,
Windows doesn't know about these drivers unless the user manually tells
WIndows about them after they are installed with 'setup.exe'. If the OP
didn't do that, then there's no need to undo it. Of course, if the OP
doesn't care about using these packages, there's no harm in uninstalling
them via 'setup.exe'. If the OP did actually run '/usr/sbin/libusb-install'
and/or 'ioperm -i', then uninstalling them, as you suggest, is a worthwhile
exercise in tracking this issue.
