Unable to see TransFlash card in USB mass storage mode?

[ltd]

Hi, I'm very keen to get linloader going and doing some things with my A780, but I the instructions say to put stuff on my TransFlash card. I have a 512MB card in there that I can see fine on the File Manager but I don't see a second volume when it's in USB mass storage mode, only the internal phone memory. Anyone know why this would be?

Here is a log of what happens when it is plugged in:

usb 1-4.1.3: new full speed USB device using ehci_hcd and address 49

As you can see.. only one device... odd?? Having said that.. is there any other way I can get stuff installed on it or get telnetted into it? I tried installing that USB mode changing application but when I select "Install" on the mpkg, nothing happens at all!

Thanks all

The problem is that the T-Flash is seen as a second LUN, and some Linux distros compile their kernels not to probe this second LUN. As written in http://www.linux-usb.org/FAQ.html#ts9 :

Q: Why do I only see one device from my multipurpose storage device?

A:Some distributions (notably Red Hat) turn off the kernel option CONFIG_SCSI_MULTI_LUN. This prevents usb-storage from automatically detecting all the devices in your removable storage device. You can either recompile your kernel with this option enabled or (if your distribution supports this) add the following line to /etc/modules.conf;

options scsi_mod max_scsi_luns=15

If you do not want to do this for all SCSI devices then you can tell the kernel to scan for a specific device using;

echo >/proc/scsi/scsi "scsi add-single-device 0 0 0 1"

The first zero is the host id (so it is zero if this is your first "SCSI" adapter, check "cat /proc/scsi/scsi" to see which is your USB Storage device), the second the channel (which for usb-storage should always be zero I believe), the third is the target (which again is always 0 for usb-storage) and the last is the LUN. LUN 0 is the only one probed if this kernel option is off, so you'd need to repeat this command as root for every media type your device accepts increasing the LUN number.

Thank you so much, that makes 100% perfect sense. I wouldn't normally compile that in on a desktop because it's unusual I'd see a USB mass storage device with more than one LUN.
