Don't look for da anything. Look for mmcsd something. The sdhci_pci
driver provides disks that are mmcsdX. Looks like card change
interrupts aren't happening, or there's something else making the
driver unhappy with the SDHCI controller though...

Is a device created for the empty reader?  It's worth trying to force a 
retaste of that device with 'true > /dev/daX' after the card is

Whoops, I should send this to freebsd-stable instead of freebsd-usb.
Sorry! -- George

Ah!  It didn't occur to me to run pciconf.  "pciconf -lv" shows this:

sdhci_pci0@pci0:0:20:7: class=0x080501 card=0x08651025 chip=0x78131022
rev=0x01 hdr=0x00
vendor = 'Advanced Micro Devices, Inc. [AMD]'
device = 'FCH SD Flash Controller'
class  = base peripheral
subclass   = SD host controller

So not only is it (apparently) recognized, but the sdhci_pci driver
attached to it!  But inserting or removing a card shows no activity.
What's my next step?  -- George

Clandestine USB SD card slot

[George Mitchell]

FreeBSD 10.3-RELEASE-p7 #0: Thu Aug 11 18:38:15 UTC 2016
Acer Aspire E15
There is a slot on the front of this laptop which sure looks like an
SD card slot, which I hope corresponds to one of these:

ugen1.1:  at usbus1, cfg=0 md=HOST spd=HIGH (480Mbps)
pwr=SAVE (0mA)
ugen0.1:  at usbus0, cfg=0 md=HOST spd=SUPER
(5.0Gbps) pwr=SAVE (0mA)
ugen2.1:  at usbus2, cfg=0 md=HOST spd=HIGH (480Mbps)
pwr=SAVE (0mA)
ugen1.2:  at usbus1, cfg=0 md=HOST
spd=HIGH (480Mbps) pwr=SAVE (100mA)
ugen2.2:  at usbus2, cfg=0 md=HOST
spd=HIGH (480Mbps) pwr=SAVE (100mA)
ugen0.2:  at usbus0, cfg=0 md=HOST
spd=SUPER (5.0Gbps) pwr=ON (224mA)
ugen1.3:  at usbus1, cfg=0 md=HOST spd=FULL
(12Mbps) pwr=SAVE (100mA)
ugen2.3:  at usbus2, cfg=0 md=HOST
spd=FULL (12Mbps) pwr=ON (100mA)
ugen1.4:  at usbus1, cfg=0 md=HOST
spd=LOW (1.5Mbps) pwr=ON (100mA)
ugen1.5:  at usbus1, cfg=0 md=HOST spd=FULL
(12Mbps) pwr=SAVE (100mA)
ugen1.6:  at usbus1, cfg=0 md=HOST
spd=FULL (12Mbps) pwr=ON (100mA)
ugen1.7:  at usbus1, cfg=0 md=HOST
spd=FULL (12Mbps) pwr=ON (100mA)
ugen1.8:  at usbus1, cfg=0 md=HOST
spd=HIGH (480Mbps) pwr=ON (500mA)

But inserting a card into the slot produces no results, even with
sysctl hw.usb.umass.debug=1 hw.usb.ugen.debug=1 hw.usb.dev.debug=1.
(sysctl hw.usb.debug=1 produces way too much output all the time.)
Any suggestions on how I can get this slot to overcome its shyness?
