You can't. USB does not work like that. Neither the device, nor the device driver know how many hubs there are in the chain, nor what the path is through the hubs, nor do they care. Perhaps you need to state the actual problem you are trying to solve, rather than spend a lot of time trying to solve the wrong problem.

Perl is Huffman encoded by design.
