  • Fixed regression that broke CMSIS-DAPv2 support.
  • Better testing of USB device interfaces to detect CMSIS-DAPv2. It now properly selects the v2 interface on a device with multiple interfaces with "CMSIS-DAP" in the name.
  • Further cleanup of libusb error log messages. Logging of some errors was removed. The log messages about permissions issues on Linux are restricted to one message per VID/PID pair per process lifetime. These changes stop all log spewage that happened on Windows or Linux when pyOCD waits for a probe to be connected.
