"I took your advise, and copied/moved the contents of folder [1] into [UF] & [UV] and edited the masstorage.ini to reflect these changes. However; i was greeted with another BSOD, this time STOP $7E in WDFLDR.SYS."
Actually, the error was a STOP $0000007E {0xC0000005,0xF6D61211,0xF78DA4D4,0xF78DA1D0}.
I wonder if combining the main controller device HWid's with those of the Hub Controller may have caused this issue.
