[dorkbotpdx-blabber] How does the AT90USB162 bootloader know of which method

[Transistor Toaster]

I think I might have emailed this to myself but not the mailing list, so
pardon me if this is a double post.

Hello,
I was just wondering how does the AT90USB162 know which particular
programming method is to be used? If I hold nHWB low and pulse the RESET
line, how does it know it is supposed to talk to the PC with the USB
port and not JTAG or ICSP?
