Device changes vendor:product in negotiation

[lelcuk]

Hi
not sure if this classifies as issue, probably more like an enquiry or feature request.... anyway
Some usb devices when plugged-in enumerates as vendor:product, however as some points they will reset connection and switch to a different vendor:product...
Is there a way to follow a device throughout those changes? i.e. modify the proxy vendor:product as indicated from the data exchange between the devices?
Alternatively, would it be possible to proxy a physical usb port and not a specific vendor:product?

TIA
Alon
