I've uploaded the usbmon traces here: https://www.dropbox.com/sh/0gldb4r4g6p4p5w/AAAdmHP_Slya3f440v9oe1qka?dl=0 One run tracing every bus (0u), one run tracing only the sandisk stick (2u). Each trace is from starting to copy the files to the point it hangs up, at which I attempt to cd into the mount point.
