Hi all,
I have a bit of a mystery on my hands with mounting an sdcard in my printer. After I turn on the printer, the log says:
Oct 25 22:16:11 zaphod kernel: usb 2-1: new full speed USB device using uhci_hcd and address 7 Oct 25 22:16:11 zaphod kernel: usb 2-1: configuration #1 chosen from 1 choice Oct 25 22:16:11 zaphod kernel: scsi13 : SCSI emulation for USB Mass Storage devices
Then I insert the card. The log now says:
Oct 25 22:16:16 zaphod kernel: scsi 13:0:0:0: Direct-Access HP PSC 2355 1.00 PQ: 0 ANSI: 2 Oct 25 22:16:16 zaphod kernel: sd 13:0:0:0: [sdb] Attached SCSI removable disk
Then, when I do
# ls /dev/sdb*
I only get:
/dev/sdb
So that's the card only, no filesystem. I know it has one partition, formatted as vfat. Then I do this:
# sudo mount -t /dev/sdb /mnt/sdcard
It responds with:
mount: wrong fs type, bad option, bad superblock on /dev/sdb, missing codepage or other error In some cases useful info is found in syslog - try dmesg | tail or so
instead of telling me I should be mounting a filesystem and not the medium itself. At the same time, this is added to the log:

So, trying to mount the card has triggered the kernel into finding the sdb1 file system (I waited a quarter of an hour to make sure my computer wasn't just being slow). Now I can mount and access sdb1 without problems.
Can someone tell me what could be causing this and how I can set things up so that when I turn on my printer and insert a card, its file system is recognized immediately?
Thanks for any help,
diederick

maybe you don't have the vfat compiled in.. or you don't have the module loaded. just a guess. good luck.
