Boot my plan9 today with my usb connected, it worked! Now i could access
my files using my usb. on my system, if it can detect my usb during fresh
boot why it can't detect while the system is already running?

The introduction on operating system abstraction by Mr. Francisco
Ballesteros is nice, very well explained that even a beginner like me could
easily understand.

thanks
