[Alauda] Unable to mount picture cards in openSUSE 10.3 and later

[Karl S. <sch...@gm...>]

Ladies and Gentlemen,

I believe that I may have stumbled upon the reason as to why the alauda driver 
is able to mount picture cards perfectly in openSUSE 10.2, yet is unable to 
mount them in oS 10.3 and later. In oS 10.2, the hard disks were labeled as 
hda, hdb, etc. However, starting in oS 10.3, the labelling has changed to 
sda, sdb, etc. In oS 10.2, as well as in Windows, the Xd and Sd slots of my 
Olympus MAUSB-10 register as sda and sdb, respectively.

Is it possible that there is a conflict here? It seems that the alauda driver 
wants to label these slots as sda and sdb, but is unable to do so, because 
these labels are already taken by the hard disks in oS 10.3 and later. 
Perhaps the driver is unable to assign alternate scsi-device ids, and as 
such, just gives up, thus leaving picture cards unmounted.

Please look into this matter as soon as possible.

[Alauda] How to obtain usuable block number in the card?

[Harsh V. <hj...@gm...>]

Hi,
I am working with 1 GB xD-Picture card and trying to figure out its specs.
I am reading logs from usbsnoop and have find out that it also has 512 as
page size and 32 pages per block.
I am wondering how could you obtain the usable block size and also number of
zones in the card.
I used libusb.
usb_bulk_write ( 0x40, 0xb4, pba_hi, pba_zone, 0, pba_lo + page_offset,
pages, 0, 0) -- I can use this command to write (at least it look like) for
any value of pba_hi, pba_lo and pba_zone. How could I figure out which pages
are safe to write?
TIA
