This is what I was trying to get at last night, but people kept confusing the issue. We have not verified that EHCI is correctly routed. There are two easy ways to check that. Don't load EHCI at boot time, and see if the device gets enumerated (per USB requirements, the device must talk at 1.1 speeds, even if it would prefer not to). If it does, then we've found our culprit. On the other hand, since we know that OHCI is good, if it doesn't enumerate without EHCI, then obviously something else is wrong. Like I just said, I doubt that Insyde went out of their way to make wireless work - so we need to stop looking for secret sauce that only affects the wireless and start looking at issues on the fundamental busses at play here. Step one is to get rid of EHCI.
