USB RH7.1 SDDR-31

I want to download some pictures from a compactflash memory card using my Sandisk SDDR-31 compactflash reader. The SanDisk plugs into the USB but I don't know how to mount the thing.

Since this is RH7.1, the kernel already has USB support. Here is the printout from the /proc/bus/usb/devices file:

T:  Bus=01 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#=  1 Spd=12  MxCh= 2
B:  Alloc=  0/900 us ( 0%), #Int=  0, #Iso=  0
D:  Ver= 1.10 Cls=09(hub  ) Sub=00 Prot=00 MxPS= 8 #Cfgs=  1
P:  Vendor=0000 ProdID=0000 Rev= 0.00
S:  Product=USB OHCI Root Hub
S:  SerialNumber=c4861000
C:* #Ifs= 1 Cfg#= 1 Atr=40 MxPwr=  0mA
I:  If#= 0 Alt= 0 #EPs= 1 Cls=09(hub  ) Sub=00 Prot=00 Driver=hub
E:  Ad=81(I) Atr=03(Int.) MxPS=   2 Ivl=255ms
T:  Bus=01 Lev=01 Prnt=01 Port=01 Cnt=01 Dev#=  2 Spd=12  MxCh= 0
D:  Ver= 1.10 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs=  1
P:  Vendor=0781 ProdID=0002 Rev= 0.09
S:  Manufacturer=SanDisk Corporation
S:  Product=ImageMate CompactFlash USB
S:  SerialNumber=000000000002
C:* #Ifs= 1 Cfg#= 1 Atr=40 MxPwr=100mA
I:  If#= 0 Alt= 0 #EPs= 2 Cls=08(stor.) Sub=06 Prot=50 Driver=usb-storage
E:  Ad=82(I) Atr=02(Bulk) MxPS=  64 Ivl=  0ms
E:  Ad=02(O) Atr=02(Bulk) MxPS=  64 Ivl=  0ms

So clearly, my system recognizes the SanDisk reader. Mounting the thing is probably trivial, but I can't find the information on how to do it. Someone know how?

USB mass storage devices are handled under the SCSI subsystem, so you'll need to mount it as if it were a SCSI hard disk.

If you have no other SCSI devices, it's probably going to be something like

insmod usb-storage
mount /dev/sda1 /mnt/<your-mount-point>

Have a look at this link:

Compact flash cards are covered in the PCMCIA HOWTO.

> SDDR-31 USB Compact Flash Image mate  > General
doesn't list any compatibility with the Linux system though.

Sorry it took me a while to get back to this -- I had to actually work for a while. ;-)

vsamtani was correct. I thought I had already tried what you suggested, but I guess not because it worked perfectly.

BTW, this is not a PCMCIA issue. I don't have PCMCIA and I did not even include the PCMCIA protions for the kernel. The connection is USB.

Anyway, thanks for the suggestions and an extra thanks for the link. I searched and searched for something like that and could not find it out there until you posted it here. I'd say that rates an A.

My sincere gratulations to that answer, Vijay.
It sounds so simple when you really know the answer : )
I mean that's what I like with Linux: it (often) allowes you to find
a workable solution for your setup even when the
manufacturer states ' non compatibility ' or ' no Linux driver's ' available '.
Glad you found it !

Sorry 'crouchet' that I only came up with such a weak idea.
Had better days ; |  
Anyway, at least Vijay brought back some
Linux confidence for me too. Thanks.

Wow, I just realized that in my searching I got all the way to the page just before the link you posted above. I just did not click on the "More Info" tag. So close and yet so far...

Once you find the right place to look it is easy but I know the real trick is knowing where to look. For instance, I know that IBM has a nice paper on how to set up a stateful firewall using iptables. But if I did not know that I would probably have a difficult time finding how to set up such a firewall. It is not much good for Linux to have a lot of nifty new features but require an extended search to figure out how to use them. Most users won't bother.

Gee, is that me up on that soap box?

Linux documentation is always a headache, sometimes because it doesn't exist, but more often because it's plain wrong. It's a shame there isn't a pool of talented volunteers whose passion in life is documenting, rather than coding....

Thanks for the kind words from xberry and crouchet :)
