Description

Some probes running DAPLink are not detected on Windows with pyOCD.

Our tests have determined that this is down to the DAPLink version with 0240 and above working fine, but 0226 not being found (on Windows only). Our testing has been limited by the hardware we can locate.

The older device is found, can be flashed and debugged on a Mac, so this is purely a Windows issue.
Also, we have found that mbedls correctly finds all boards on mac and Windows no matter the DAPLink version.

Research direction

No source files or tests are named. Start by reproducing Windows detection with a DAPLink 0226 probe and compare pyOCD's behavior with mbedls, which reportedly finds the board. Done means older DAPLink devices are detected on Windows while existing flashing and debugging behavior remains intact.
