| On Windows, hidapi's hid_device_info |
|
|
| carries a product_string field (wchar_t*). |
|
|
| Enumerate all Logitech devices and find |
|

| the one whose path matches `path`. |

|
| Caveat: Windows hidapi typically returns the |
|
|
| parent product string on every (interface, |
|
|
| usage_page, usage) entry that maps to the same |
|
|
| USB device, so Centurion sub-devices may share a |
|
|
| name with the parent dongle. That's a less |
|
|
| specific name than Linux's HID_NAME, but still |
|
|
| better than "Logitech Centurion Device". |
