Go to
"Settings / Xperia / USB Connectivity"
and set "USB conntection mode" to:
"Mass storage mode(MSC)"
Then connect device to PC and see:
lsusb | grep -i sony
Bus 001 Device 009: ID 0fce:e193 Sony Ericsson Mobile Communications AB
Good. Next:
lsscsi | grep -i sony
[5:0:0:0] disk SONY Mass Storage 0100 /dev/sdd
Nice. And finaly:
dmesg -T | tail

Excelent! But:
grep sdd /proc/partitions
No output! And:
ls /dev/sdd*
/dev/sdd
I expected more here, but there are no partitions. So I try to help kernel:
partx -a /dev/sdd
partx: /dev/sdd: open failed: No medium found
And last hope died:
mount /dev/sdd /mnt/usb
mount: no medium found on /dev/sdd
Summary: operating system completely identifies our device and allocates it block device. Though it cannot be mounted or used in any way. What's wrong here? What for this "Mass storage mode(MSC)" exists if we can't use it?
Yes, I still can access device in "Media transfer mode(MTP)" with gmtp, but it hangs on middle of download from device and can not provide functionality of block device with standard utilities.
