Hi,
This strikes me as odd. I have a 1GB USB pocketknife that doesn't
give me the right device nodes until after I try to mount it. The
mount attempt seems to create the proper device nodes.
The USB drive shows up on insertion like so:
Apr 14 19:09:41 stretchlimo kernel: umass0: <SWISSBIT Victorinox 2.0, class 0/0, rev 2.00/2.00, addr 2> on uhub4
Apr 14 19:09:41 stretchlimo root: Unknown USB device: vendor 0x1370 product 0x2168 bus uhub4
Apr 14 19:09:41 stretchlimo kernel: da1 at umass-sim0 bus 0 target 0 lun 0
Apr 14 19:09:41 stretchlimo kernel: da1: <SWISSBIT Victorinox 2.0 2.00> Removable Direct Access SCSI-2 device
Apr 14 19:09:41 stretchlimo kernel: da1: 40.000MB/s transfers
Apr 14 19:09:41 stretchlimo kernel: da1: Attempt to query device size failed: UNIT ATTENTION, Not ready to ready change,
Disklabel tells me that it has a single DOS partition on it:
# fdisk /dev/da1
******* Working on device /dev/da1 *******
parameters extracted from in-core disklabel are:
cylinders=998 heads=64 sectors/track=32 (2048 blks/cyl)
parameters to be used for BIOS calculations are:
cylinders=998 heads=64 sectors/track=32 (2048 blks/cyl)
Media sector size is 512
Warning: BIOS sector numbering starts with sector 1
Information from DOS bootblock is:
The data for partition 1 is:
sysid 6 (0x06),(Primary 'big' DOS (>= 32MB))
start 32, size 2043871 (997 Meg), flag 80 (active)
beg: cyl 0/ head 1/ sector 1;
end: cyl 996/ head 63/ sector 32
The data for partition 2 is:
<UNUSED>
The data for partition 3 is:
<UNUSED>
The data for partition 4 is:
<UNUSED>
But the only device node I get upon insertion is:
# ls /dev/da*
/dev/da1
#
I try to mount it, and immediately check the device nodes:
# mount_msdosfs /dev/da1 /media
mount_msdosfs: /dev/da1: : Invalid argument
# ls /dev/da*
/dev/da1 /dev/da1s1
#
Of course, at this point I can mount_msdosfs /dev/da1s1.
Is this behavior normal? I'm trying to configure devd to automount a
USB device, but the lack of a proper device node appearing the first
time around kiboshes that.
This is a 7.x i386 system.
Thanks,
==ml
