Hey all, I've been encountering a problem with my MBP. It seems that when in Windows 7 Ultimate, (I'm using bootcamp to do so), my MBP is only able to use a thumbdrive once irregardless of whether it is new or a used one. However with external HDD or with other peripheral USB devices, it's alright. What seems to be the problem actually? Is it hardware related problem, or OS problem? This problem sometimes occurs on my Mac OS Lion too.
