Yes, if the "protocol" of message passing is in the
public domain.
Most of the vendors form an implementor's forum, where
they prepare a closed/open standard for
interfaces/protocols. USB-IF is an open standard:
http://www.usb.org. All the IETF RFCs are open
standards.
How each vendor implements the standard could be
different and is proprietary. As long as they adhere
to the standard, their product should be compliant and
they can market it to customers. So, you can use Logic
Analysers, snoopers to capture the packets and analyze
what is being transmitted, by comparing the outputs
*with* the open standard protocol.
But, some forums are closed, so you will never know
what protocols are used. Secure Digital, for example.
You will need to pay heavy licensing fees, which
individuals cannot afford to pay. Only companies can
afford such pricing.

Yet, SD is supported in the Linux kernel, thanks to
feedback from developers in the community.
These days, lot of R&D companies use GNU/Linux, have
support for it, and contribute to it. Its just that
few players are yet to comply.
