 |
|
Hello,
Not sure if anyone's come across this, but I have a Motorola Atrix... when I mount it as USB storage, I can only access one of the block devices - i.e. it has ~10GB internal storage and a 16GB microsd card. the expected behaviour is to see both devices as seperate block devices, say sdc/sdd - but I can only see sdc.
I guess I have to suspect udev here...? Does anyone else have this issue (or more interestingly, not have this issue?)
looking at dmesg... I wonder if it's 'giving both' sdc so the second is all ~I see... I need to have a fiddle I think...

Did you solve this issue? I'm about to buy an Atrix, but if this happen I will have a headache (I had the same issue with my last phone, a Motorola Z6).
Googling around, I found that maybe you don't have set CONFIG_SCSI_MULTI_LUN in your kernel config... |

I don't have an Atrix, but I do have several devices that *should* mount their SD cards separately. This didn't work until I went into the kernel and changed the SCSI driver to probe all LUNs.
CONFIG_SCSI_MULTI_LUN=y
Once I set this, that problem went away.
