I'm trying to get to my phone's filesystem through USB in Wammu, but I'm stuck in the configuration wizard when it asks for a USB device name. After about an hour of Internet searching, here are the failed solutions I've already tried, starting with the relevant information returned by lsusb in terminal.

lsusb
Bus 001 Device 003: ID 12d1:101e Huawei Technologies Co., Ltd.

So I tried opening Wammu through sudo wammu in terminal and inputting "/dev/bus/usb/001/003" as the device name, which returns:

Error opening device
Device /dev/bus/usb/001/003 does not exist!

and then "/dev/bus/usb/001/", which returns:

Failed to connect to phone
Description: Error opening device. Unknown, busy, or no permissions.<br>
Function: Init<br>
Error code: 2

Another proposed solution was to try "tail -f /var/log/messages" in terminal. But that only returned a "No such file or directory" message.

Seemingly relevant dmesg info:

[ 4739.716214] usb 1-1: new high-speed USB device number 8 using ehci_hcd
[ 4739.854137] scsi9 : usb-storage 1-1:1.0
[ 4740.854416] scsi 9:0:0:0: CD-ROM            HUAWEI T Mass Storage     2.31 PQ: 0 ANSI: 2

[ 4740.870464] sr 9:0:0:0: Attached scsi generic sg1 type 5

I don't know why it is coming up as CD-ROM. But there it is.

If you haven't noticed already, I'm an absolute beginner when it comes to Linux and terminal. So speaking to me like I'm a three year old is welcome if you can propose a solution.

I'm running Ubuntu 12.04 LTS, and the phone is a Huawei U1250. My computer is an Acer Aspire One D250/KAV60. Any help is much appreciated.
