>Description:

This is an SD micro card in an SD adapter:

umass0 at uhub3 port 2 configuration 1 interface 0
umass0: Generic Mass Storage Device, rev 2.00/1.00, addr 2
umass0: using SCSI over Bulk-Only
scsibus0 at umass0: 2 targets, 1 lun per target
sd0 at scsibus0 target 0 lun 0: <Multiple, Card  Reader, 1.00> disk removable
sd0: drive offline
sd0(umass0:0:0:0):  Check Condition on CDB: 0x00 00 00 00 00 00
    SENSE KEY:  Not Ready
 COMMAND INFO:  11162945 (0xaa5541)
     ASC/ASCQ:  Medium Not Present

sd0: unable to open device, error = 19

Now, you might say the adapter is broke. Tested three or four adapters with
different SD micro cards to be sure. The SD micro cards were for sure working.
Although some of the SD adapters were questionable, some of them were still
known to work.

I thought this may have been a problem with the device itself, which is why i
didn't bother reporting it until i found a normal SD card. The SD card works
fine. sd0 attaches and i can read/write to the drive, so it's not the device.

Dmesg is in PR pkg/46919.

>How-To-Repeat:
Put an SD micro card in an SD adapter. Insert it into SD slot. `dmesg | tail`

 Have actually tried to mount your sd card? I am getting the same
 output like you but I can still to mount it as /dev/sd3d in my card
 reader (SD card readers usually have several slots and it can be that
 your sd card can be attached not to sd0 but to sd1, 2 or 3). Though I
 don't know what this output actually means.

 This is a bit strange - i tried again with another SD micro card in my
 adapter. The first time, it was detected as sd0 with the device not ready
 error. The way the slot works is you insert the adapter, it clicks, then
 retreats about 3mm. I decided to shove the adapter all the way in, not letting
 it retreat. It was detected as sd1 on umass1 (so, i suppose that it was also
 showing up as sd0 - i just saw the tail of dmesg). Then, the machine locked
 hard. I had to power cycle it. When it came back up, the device was being
 detected as sd0, but disklabel showed the MSDOS partition on sd0e, instead of
 a 4.2BSD partition on sd0a. I was able to mount sd0e and browse the file
 system.

 The only thing that changed was how i was inserting the card. Before,
 i just shoved it in the slot. Then, i was making sure that the card was either
 1) as far down the Z axis as it could go and then 2) as far up the Z axis in
 the slot it could go. Neither seemed to make a difference. There doesn't
 appear to be any internal grooves in the adapter that would allow such an
 insertion. After it was deteced as sd0 with the MSDOS partition on sd0e,
 everything just seemed to work fine. So, i suppose this PR can be closed,
 although the whole procedure was rather strange and also that the machine hard
 locked with the adapter shoved all the way in the slot.

 I would suspect the card, or a defective adapter.  MicroSD is the same as f=
 ull size SD apart from the physical size -- the adapter merely connects a b=
 ig connector to a small one.  No protocol conversion or signal level change=
 s are involved.  The adapter merely delivers electrons without processing.
