I'm hoping some USB knowledgeable persons can help with this USBTMC (Test & Measurement Class) question...
USBTMC prescribes two descriptors that are supported under 2.0 but not1.1. They are the device qualifier and other-speed configuration descriptors. Neither have anything to do with USBTMC. Instead they seem to exist for 2.0 high-speed support.
Does anyone know if it's a violation of the the USBTMC standard to implement USBTMC under the 1.1 standard thus forgoing the two extra 2.0 descriptors?
