OSError: exception: access violation writing 0x00000014

I get this exception consistently, but it doesn't seem to affect that actual functionality.

Platform: CY8CKIT_062_WIFI_BT
pyOCD version: 0.23.0a2.dev28
python version: 3.7 32 bit
OS: Windows 10

Per the Readme, I've tried downloading and placing libusb v1.0.21 files (.dll, .lib, & .pdb) from M32/dll folder within libusb-1.0.21.7z) alongside python.exe, but this doesn't seem to help.

Reproduce pyocd commander on the CY8CKIT_062_WIFI_BT with Python 3.7 32-bit on Windows 10, then inspect usb/backend/libusb1.py, especially _finalize_object, and the reported libusb files. Done means the command no longer emits the access-violation traceback while retaining the reported device connection and functionality.
