populated. Apparently, if you use an ehci controller, it's not. Use usbd_device2interface_handle() to retrieve the interface handle. NOTE: uaa->iface is populated in the probe routine, so I suspect the fact that it's NULL in the attach routine is a bug in the ehci driver. Also, don't depend on the PHY addresses returned by the AXE_CMD_READ_PHYID command. The address is correct for my LinkSys NIC, but a user has reported that with a D-Link NIC, the PHYID command returns address 4 while the attached Broadcom PHY is in fact strapped for address 0. Instead, latch onto the first PHY address that returns valid data during a readreg operation.
