Do you have any measurement instruments which have a USB Female Type B connector?
If you said yes, Great! You most likely have USBTMC devices!
I made USBTMC Host driver for USB Host Shield 2.0.
USBTMC (USB Test and Measurement Class) is a set of standard device class specifications, built on top of the USB standard.
This driver allows you to communicate with Measurement Instruments.
I wrote a simple example using this driver.
You can communicate with your measurement instruments like below.
I also made a demonstration on Youtube.
I have USBTMC Host driver repository on GitHub.
If you have any questions, please feel free to make issues.
I hope this will help others.
