 |
|
I just bought a Sony PRS T1 e-reader and added a 32GB micro SD memory card to it. My laptop is an old MacBook with dual boot into OSX and Gentoo. If I boot into OSX and connect the e-reader by USB, I see two volumes: the e-reader onboard memory and the sd card, and can transfer files between the two. If I boot into gentoo, I see only the e-readers main memory, which appears as /dev/sdb and gets mounted automatically in /media/. I have no access to the SD card at all. Because it works in OSX I know there's no hardware problem with the Sony or the macbook.
lsusb shows:

dmesg gives me this:

A guess:
Do you have SCSI LUN support enabled in your kernel? Some multi devices show up as different LUNs.

You were right - turned on 'Probe all LUNs on each SCSI device' and all is fine. Funny how obvious things are once someone else has told you the answer!
Thank you |
