Hi,
The USB stack performs the same EHCI/OHCI/UHCI/XHCI reset which is does
during power on, when it resumes. Ensure the ports are powered. +5V.
Might be a BIOS/PCI/ACPI issue.
--HPS
Is there something in the output of usbconfig that I can poke at to see
if the hardware *thinks* it is powered on?
sean
Yes, there is the port status.

It is probed regularly by the UHUB driver and the port status is printed
in dmesg.
Turn on like this:
sysctl hw.usb.uhub.debug=16
By resetting the root HUB, you can write new power on bits:
usbconfig -d X.1 set_config 255
usbconfig -d X.1 set_config 0
--HPS
Well, that's problematic. The USB tree looks like this normally:
ugen0.1: at usbus0, cfg=0 md=HOST spd=FULL
(12Mbps) pwr=SAVE (0mA)
ugen1.1: at usbus1, cfg=0 md=HOST spd=FULL
(12Mbps) pwr=SAVE (0mA)

ugen4.1: at usbus4, cfg=0 md=HOST spd=FULL
(12Mbps) pwr=SAVE (0mA)
ugen5.1: at usbus5, cfg=0 md=HOST spd=FULL
(12Mbps) pwr=SAVE (0mA)
ugen6.1: at usbus6, cfg=0 md=HOST spd=HIGH
(480Mbps) pwr=SAVE (0mA)
ugen0.2: at usbus0, cfg=0
md=HOST spd=FULL (12Mbps) pwr=ON (100mA)
But, on resume ... sometimes ... ugen0.1 is just flatout gone (along
with the ugen0.2 device, obviously). This only seems to happen with
various USB device plugged in (tried about 4 different make/model usb
sticks and ext drives).
So, resetting doesn't work as the device is literally gone. Thoughts?
sean
Setting hw.usb.debug=15 should give you some hints. Are you sure the PCI
device is still there after resume?
--HPS
I did a pre/post resume pciconf -lv and I see no difference between the
two.
On initial resume, ugen0.1 appears to be there in usbconfig output, but
trying to set_config on it, causes it to dissapear and causes usbconfig
to hang:

Hi,
What kind of USB devices are attached? Are any of these USB devices
preventing detach? Could you check the USB threads using kgdb?

Well, that's problematic. The USB tree looks like this normally:
ugen0.1: at usbus0, cfg=0 md=HOST spd=FULL
(12Mbps) pwr=SAVE (0mA)
ugen1.1: at usbus1, cfg=0 md=HOST spd=FULL
(12Mbps) pwr=SAVE (0mA)
ugen2.1: at usbus2, cfg=0 md=HOST spd=HIGH
(480Mbps) pwr=SAVE (0mA)
ugen3.1: at usbus3, cfg=0 md=HOST spd=FULL
(12Mbps) pwr=SAVE (0mA)
ugen4.1: at usbus4, cfg=0 md=HOST spd=FULL
(12Mbps) pwr=SAVE (0mA)
ugen5.1: at usbus5, cfg=0 md=HOST spd=FULL
(12Mbps) pwr=SAVE (0mA)
ugen6.1: at usbus6, cfg=0 md=HOST spd=HIGH
(480Mbps) pwr=SAVE (0mA)
ugen0.2: at usbus0, cfg=0
md=HOST spd=FULL (12Mbps) pwr=ON (100mA)
But, on resume ... sometimes ... ugen0.1 is just flatout gone (along
with the ugen0.2 device, obviously). This only seems to happen with
various USB device plugged in (tried about 4 different make/model usb
sticks and ext drives).
So, resetting doesn't work as the device is literally gone. Thoughts?

Hi,
The USB stack performs the same EHCI/OHCI/UHCI/XHCI reset which is does
during power on, when it resumes. Ensure the ports are powered. +5V.
Might be a BIOS/PCI/ACPI issue.

Is there something in the output of usbconfig that I can poke at to see
if the hardware *thinks* it is powered on?
sean
Yes, there is the port status.

It is probed regularly by the UHUB driver and the port status is printed
in dmesg.
Turn on like this:
sysctl hw.usb.uhub.debug=16
By resetting the root HUB, you can write new power on bits:
usbconfig -d X.1 set_config 255
usbconfig -d X.1 set_config 0
