Description

I'm connecting to my target via a SEGGER J-Link.
I get the following warning about STLink and CMSIS-DAPv2 probes not being supported.
[ WARNING] STLink and CMSIS-DAPv2 probes are not supported because no libusb library was found

Is there a way to prevent this warning when using a J-Link?

Thanks

Research direction

Start by tracing how pyOCD detects the J-Link connection and emits the libusb warning about unsupported STLink and CMSIS-DAPv2 probes. Determine where that warning is produced and verify the behavior with a J-Link connection; done means using a J-Link no longer emits this irrelevant warning.
