The USB 2 driver is not installed in the generic kernel in 5.3 and 5.4 Release (I haven't checked 5.4 stable or 6.0), so by default you get only USB 1 speeds. 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 _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
