>Synopsis: rw mount on read-only usb-sticks leads to unusable usb port
>Category: system usb
>Environment:
System : OpenBSD 5.1
Details : OpenBSD 5.1 (GENERIC.MP) #207: Sun Feb 12 09:42:14 MST

[email protected]:/usr/src/sys/arch/amd64/compile/GENERIC.MP
Architecture: OpenBSD.amd64
Machine : amd64
>Description:
With some usb-sticks which have a read-only switch the status is not
correctly detected. When you accidently mount such a stick read-write
it is not possible to use the usb port anymore until you reboot the
system.
>How-To-Repeat:
On the testsystem I have two usb-sticks. Both have a ffs filesystem.
That one with iSerialNumber 1916060078113E00 works as expected and that
one with iSerialNumber 08AD320000003957 not.
The easiest way to verify that the read-only status is correctly
detected is by running fsck:
fsck on iSerialNumbeR 1916060078113E00
# fsck /dev/sd1a
** /dev/rsd1a (NO WRITE)
** File system is clean; not checking
=> Stick is in read-only position and so the no write state is correct
fsck on iSerialNumber 08AD320000003957
# fsck /dev/sd0a
** /dev/rsd0a
** File system is clean; not checking
=> Stick is in read-only position and the no write state is missing
When you try to mount /dev/sd1a you get directly a "Permission denied"
message:
# mount /dev/sd1a /mnt/
mount_ffs: /dev/sd1a on /mnt: Permission denied
=> So everything is ok with this stick
With /dev/sd0a the sticks gets mounted and a error messages appears in
dmesg
# mount /dev/sd0a /mnt/
# dmesg
....
sd0(umass0:1:0): Check Condition (error 0x70) on opcode 0x2a
SENSE KEY: Write Protected
ASC/ASCQ: Write Protected
# df
....
/dev/sd0a 7772668 4 7384032 0% /mnt
When you try to umount the stick you get more error messages:
# umount /dev/sd0a
# dmesg
....
sd0(umass0:1:0): Check Condition (error 0x70) on opcode 0x2a
SENSE KEY: Write Protected
ASC/ASCQ: Write Protected
sd0(umass0:1:0): Check Condition (error 0x70) on opcode 0x2a
SENSE KEY: Write Protected
ASC/ASCQ: Write Protected
# df doesn't how the mount anymore
As of now the stick and the usb port is not usable anymore.
When you try to mount it read-only:
# mount -o ro /dev/sd0a /mnt/
mount_ffs: /dev/sd0a on /mnt: Device busy
Even if you remove the stick and reattache it there are no new dmesg
entries and you can still not use the usb port anymore until you
reboot the system.
On a linux system the read-only state is correctly detected for both
sticks.
If I can do anything else to help with this problem please let me know.
