I've had success in working around the ehci-hcd error by recompiling the kernel WITH power management (CONFIG_PM=y) but WITHOUT ACPI support (CONFIG_ACPI not set). With this done, EHCI seems to be behaving... at the very least, it's not flooding my syslogs with "new high-speed USB device" messages and isn't squawking over a couple of large file transfers I'm doing right now.
That won't help those of you who depend on ACPI for power management, but...
