Public bug reported:
Since recently, Ubuntu 9.04 has added MTP support for media players that
support it. The problem with this is that it prevents devices from
mounting as mass-storage devices (I've recently tried this on both a
Sony NWZ-S618F and a Sansa m230).
The output of dmesg is:
[ 6395.124091] usb 2-3: new high speed USB device using ehci_hcd and address 9
[ 6395.259094] usb 2-3: configuration #1 chosen from 1 choice
[ 6395.261305] scsi11 : SCSI emulation for USB Mass Storage devices
[ 6395.262326] usb-storage: device found at 9
[ 6395.262330] usb-storage: waiting for device to settle before scanning
The devices never settle, since, I assume, libmtp sets the devices to
MTP mode, in which they are unmountable, and if you want to copy to and
from the devices, you have to use an MTP-capable device to do so. Keep
in mind that the workaround for, for instance the Sansa, is to disable
MTP support on the device, other devices, like the Sony has no such
option, and are either connected in mass-storage mode, or MTP mode, not
both.
What I expect to happen:
- For Ubuntu to just mount the device, or, at the very least ask the user
whether he/she/it wants to use it as a music device or a USB mass-storage
device (or even an automated per-device preference)
What happens:
- Device is unusable. I can no longer copy files/folders to the device. This
involves losing the ability to copy other media files to the device (In
particular video)
The workaround in this case seems to be remove mtp support by removing
libmtp8 - but this has unintended side-effects: It becomes impossible to
use mtp-only devices, and rhythmbox depends on it, and so gets
uninstalled if you attempt.
