>Description:
I'm using a generic multi-standard media-card reader.
Its several slots are identified at boot-time as:
da2 at umass-sim0 bus 0 target 0 lun 0
da2: <Generic USB SD Reader 1.00> Removable Direct Access SCSI-0 device
da2: 40.000MB/s transfers
da2: Attempt to query device size failed: NOT READY, Medium not present
da3 at umass-sim0 bus 0 target 0 lun 1
da3: <Generic USB CF Reader 1.01> Removable Direct Access SCSI-0 device
da3: 40.000MB/s transfers
da3: Attempt to query device size failed: NOT READY, Medium not present
da4 at umass-sim0 bus 0 target 0 lun 2
da4: <Generic USB SM Reader 1.02> Removable Direct Access SCSI-0 device
da4: 40.000MB/s transfers
da4: Attempt to query device size failed: NOT READY, Medium not present
da5 at umass-sim0 bus 0 target 0 lun 3
da5: <Generic USB MS Reader 1.03> Removable Direct Access SCSI-0 device
da5: 40.000MB/s transfers
da5: Attempt to query device size failed: NOT READY, Medium not present
Fair enough -- at boot time the slots are all empty.
However, when I then insert a card (SD) into the proper slot
and try to mount /dev/da2s1 -- or even to `fdisk da2', the
command hangs for A LONG time...
Pressing Ctrl-T reveals, that the hang is inside `cbwait'.
During this time, a number of errors are logged on the console:
umass0: BBB reset failed, TIMEOUT
umass0: BBB bulk-in clear stall failed, IOERROR
umass0: BBB bulk-out clear stall failed, IOERROR
umass0: BBB reset failed, IOERROR
umass0: BBB bulk-in clear stall failed, IOERROR
umass0: BBB bulk-out clear stall failed, IOERROR
umass0: BBB reset failed, IOERROR
umass0: BBB bulk-in clear stall failed, IOERROR
umass0: BBB bulk-out clear stall failed, IOERROR
umass0: BBB reset failed, IOERROR
umass0: BBB bulk-in clear stall failed, IOERROR
umass0: BBB bulk-out clear stall failed, IOERROR
umass0: BBB reset failed, IOERROR
umass0: BBB bulk-in clear stall failed, IOERROR
umass0: BBB bulk-out clear stall failed, IOERROR
And the command fails eventually with "can't open device
/dev/da2: Input/output error".
The only way to get to the data, apparently, is to boot
with the card inserted -- unacceptable in most cases :(
I first observed this with the kernel from June 7, 2007.
But I was using an EXTERNAL reader before then...
The problem is still here with 6.2-stable from July 17th.
>How-To-Repeat:
>Fix:
Use an EXTERNAL card-reader, and connect it with the card
already inserted. This _may_ work...
