There is no option to specify a "port" number. USB works by walking through all attached devices, and look for the VID/PID combination you're seeing in the message. The first one found is then used.

(For some other programmers, an additional serial# could be provided, to disambiguate multiple attached programmers. USBasp doesn't offer a serial number feature though.)

In your case, there's simply no matchinng device found.

Since you're using Windows: make sure you have been setting up libusb correctly. Unlike non-Windows systems (where all devices with appropriate permissions are always found), on Windows, you explicitly have to assign any desired device for libusb usage.

I tested any possibilities. My port on desktop (z640) and win10 is Port_#0011.Hub_#0003 How to translate in -P usb:???
