I have a situation where I need to be able to determine the drive letter
assigned to a USB thumbdrive in a specific port in a specific USB hub. My
system has two hubs connected to the root hub. Each hub has 4 thumbdrives.
Users will be removing the thumbdrives and replacing them and I need to
determine the drive letter associated with each of the 8 ports. Does anyone
know a way to do this?

Determine as in ‘predict’ or determine as in ‘query’? The query is easy:
just query the mountpoints, one of which will be the drive letter. The
sdk has apis for volume mountpoint enumeration.
