Basically it's just following the USBTMC specifications and make sure you have the descriptors and USBTMC requests correctly implemented.</P><P></P><P>We don't provide with such a class in Kinetis USB stack, but it is possible, for further information please refer to <A href="http://www.usb.org/developers/docs/devclass_docs/">USB Test &amp; Measurements class specification </A></P><P></P><P>Best Regards</P><P>Jorge Alcala</P></BODY></HTML> Fri, 24 Feb 2017 04:52:31 GMT https://community.nxp.com/t5/Kinetis-Microcontrollers/new-usb-class/m-p/633132#M38134 jorge_a_vazquez 2017-02-24T04:52:31Z
