It's become apparent as machines get faster that the emagic kernel firmware
loaders (based on the ezusb loader) have a reset race. a 400MHz TiBook
never tripped it, but a 2GHz Pentium M seems to hit it about 30% of the
time. The bug is seen as a hung USB box and the kernel error:
drivers/usb/misc/emi62.c: emi62_load_firmware - error loading firmware:
error = -110
The patch below inserts a delay after deasserting reset to allow the box to
settle before a new command is issued. This affects only device startup.
