Modified files:
sys/dev/usb umass.c
Log:
Postpone I/O to the device until attach has finished. This fixes
attachment after boot in some cases where the device gets confused if
spoken to over two different pipes simultaneously (resulting in TIMEOUT
errors on requesting INQUIRY data).
This solution is far from perfect, as after umass_attach has returned
the USB stack fetches the string descriptors in order for creating the
event that is sent to userland. It just makes the chances of collisions
less likely.
