Access to Both SD-Cards via Mass-Storage-Mode ?

[thatgui]

As there are a lot of devices out in the wild that support more than one drive in Mass-Storage- Mode via USB (like a mp3 player providing internal and external memory as two drives) I wonder if it would be possible on/with the Pandora too.

I don't know how android does it, but I have several devices that do this as well, would be neat if we can access internal storeage as well

Could be risky messing with the system while its running.


Nevertheless the question remains, how to do it for both cards ?

Hmmmm. I wonder if you can use:


modprobe g_file_storage file=/media stall=0


My Pandora is packed away atm, but if that works, I could modify the Mass Storage Config Button plugin to include that option


Edit: Hmmm, after reading this (http://www.linux-usb.org/gadget/file_storage.html), I don't think it'll work.


However, it should be doable updating the op_storage.sh, by comma seperating the paths.

If somebody wants to remind me at the weekend, I'll update the Mass Storage plugin for the Config Button to allow you to do this

Hmm, doing it as described in the above link ("sudo modprobe g_file_storage file=/media/mmcblk0p1,/media/mmcblk1p1"


gives me


"FATAL: Error inserting g_file_storage (/lib/modules/3.2.26/kernel/drivers/usb/gadget/g_file_storage.ko): Is a directory"


Obviously I'm doing something wrong here (?)

Sorry, I don't think it's the /media paths you use, I think it's the /dev/mmcblk* ones. I can't remember now, and my Pandora's packed away ATM.


I might get some time later to have a look at this, however, you probably won't hear from me until Sunday, as I probably won't have internet access until then

using the devices works .. at least there is no error message, but what to do afterwards ? (thanks for the help btw.)

You basically need to follow the op_storage.sh script, hence why I said it was probably worth changing a copy of that, because it does a few other things too.


If that's worked, I'll give it a try later, update the plugin, and post it when I'm able
