-minfo may give the same results even while you use completely different media.
The media manufacturer and media sub-types are displayed by cdrecord -atip

In this case (-atip), your problem is not related to the media but to
the USB drivers.

This is a Solaris USB kernel driver bug that I reported a year ago and that
