The USBTMC protocol is part of the "VISA Library" that is used by many popular T&M applications. Initial implementations for Linux based on libusb has been created. However using one common USBTMC driver results in more benefits: - Multiple applications can share access to the same instruments. - The driver handles SRQ conflicts. - Simplifies definition of udev rules for USBTMC devices. - Simplifies development of applications using T&M instruments. The following collaborative patches meet the requirements of the IVI Foundation to implement the library based on the usbtmc driver. Improvements in the data transfer rate of over 130 MByte/s for usb 3.x connections have been measured.
