Boot Loader...?

[gopher2011]

I just have a question and it is how come i can connect my phone through usb but when i try to plug it in after i set it up in boot loader where it says "serial" then plug it in to the usb and it say "usb", it becomes disconnected with activesync? Im doing this for the Radio 1.41 upgrade, unless there is a easier way.

And also how do you turn off the phone without pulling out the battery? Havent figured that out yet and i have had this thing for a month and a half now!
Thanks
