Connecting Samsung Rugby II Phone via USB as mass storage?

Postby Argyle on Sun Jan 29, 2012 2:19 am

I have a Samsung Rugby II phone with a micro SD card in the back of it. When I plug it into the USB port it asks me what type of connection I wish to make (Media Player, PC Studio, Mass Storage). On my work computer (Linux Mint 12 64 bit) I can connect as a Mass Storage device, after having changed DisableSwitching=1 to DisableSwitching=0 in the file /etc/usb_modeswitch.conf. However, despite making sure of this same setting on my home computer (Linux Mint 12 32 bit edition), I cannot connect to the storage device. The output of lsusb follows:

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 017: ID 04e8:f000 Samsung Electronics Co., Ltd

I've run "udevadm monitor" to catch the event sequence upon plugging the device in. This is what it looks like:

KERNEL[3168.931113] add /devices/pci0000:00/0000:00:03.3/usb1/1-2 (usb)

The following appears in /var/log/syslog on plugin:
Jan 28 22:10:04 palimpsest kernel: [ 3204.693228] usb 1-2: USB disconnect, device number 18
Jan 28 22:10:08 palimpsest kernel: [ 3208.908041] usb 1-2: new high speed USB device number 19 using ehci_hcd

Jan 28 22:10:09 palimpsest usb_modeswitch: switching 04e8:f000 (Samsung Electronics: SGH-A847)

I did explore some suggestions with regards to removing libmtp-runtime package, but this did not change anything. I also tried editing /lib/udev/rules.d/39-libmtp.rules to both remove the catch-all at the end as suggested somewhere, and to add:

ATTR{idVendor}=="04e8", ATTR{idProduct}=="f000", SYMLINK+="libmtp-%k", MODE="666", GROUP="audio", ENV{ID_MTP_DEVICE}="1", ENV{ID_MEDIA_PLAYER}="1"

which merely eliminated the syslog line:
Jan 28 22:10:09 palimpsest mtp-probe: bus: 1, device: 19 was not an MTP device

None of these things cause my device to show up as a drive or be mounted. "sudo fdisk -l" does not reveal anything other than my known hard-drives.

I'm not sure what to do next. I've run out of options from the google searches. Any help would be appreciated.
Thanks,
Joshua
