Brother Printer exists & works, but won't "Install" - Why?

Check whether I understood you well.
First try: Add new printer, Windows finds printer and loads its own drivers/programme automatically. It wprks but not with the Brother drivers.
Second try: Brother package: failed
I suggest a third try: Add new printer; the printer that I wanted is not listed; continue and see of your model is listed. in the list of printers.
I had difficulties with setting up another Brother printer, and the third try solved it.

help. USB drive isn't assigned a drive letter.

Any usb flash drive I plug into my computer isn't assigned a drive letter. The physical drive shows in the "safely remove hardware" but it doesnt show up in disk management. I have tried to populate the volume thru the safely remove hardware properties window and it does pop up in the list but it doesn't stay there. This isn't a format or assign a letter problem. It's more complicated then that. Maybe one of the services needed for usb drive management was disabled? Suggestions needed. btw external usb harddrives work fine.
