You can recompile your kernel and add "device ehci" to the kernel config, or it might be possible for testing to just do a "kldload ehci". In 5.3R it is definitely described as "not finished and is quite buggy" on the man page. I tried it on my 5.4R laptop, and it locked up. Then again, the card I was using it with also seems unstable with the USB 1 driver, so I don't try to conclude much about the EHCI driver from that. "man ehci" will tell you a little more. - Bob
