XO-1.5 no longer uses any USB devices internally. We used
SDIO instead. This not only provides lower power operation
to start with, it also should allow us to suspend/resume much faster.
The peak bus throughput is much lower than USB 2.0's potential,
but still reasonable for 802.11b/g. When we move to 802.11n
(probably in a year), the SDIO interface will be more of an issue.
