MSP430F5529: MSP430 USB Firmware Upgrade Example for Python 3

Hi,

Did anyone tried to port the MSP430 USB Firmware Upgrade Example 3.1 to Python3?

I got the following:

Opening HID device HID device (vID=0x2047, pID=0x0200, v=0x0109); Unknown manufacturer; @input.inf,%hid_device_vendor_defined_range%;HID-compliant vendor-defined device, Path: \\?\hid#vid_2047&pid_0200#8&69096a7&0&0000#{4d1e55b2-f16f-11cf-88cb-001111000030}

Any ideas?

Thanks,
