4.10 USB problems

[Gregor Mosheh]

I've been using 4.10 and the EHCI driver, for an
external hard drive, for several months and just
recently a USB-related problem has started.

When the drive is plugged in it is properly recognized
by umass, etc. However, attempting to mount the drive
results in "/kernel: umass0: BBB reset failed,
TIMEOUT" being logged to dmesg, and "mount:
/dev/da0s1e: Device not configured"


Someone suggested that perhaps the problem is having
both ehci and uhci in the kernel. This seemed
unlikely, since they've both been there all along and
it worked. But I was wondering about the need for both
the UHCI driver and the EHCI driver.

(see dmesg output below) On my system, the startup
shows usb0 through usb3 as being uhci, and usb4 as
uhci. I think it also shows usb0-3 being grabbed be
EHCI, am I reading that right? Still, I have had to
run usbd with "-f /dev/usb4" for it to notice the hard
drives when they're attached.

FWIW, The usbd.conf is the standard-issue one.

Is it possible that some USB ports are being grabbed
by UHCI and some are being grabbed by EHCI? Would
rebuilding the kernel without UHCI cause all of the
ports to be EHCI? The ports and harddrives are all
USB2 anyway, so USB1 compatibility is not necessary.
