Configuration error and Fatal error. Maybe USB mode problems?

[shawninder]

Hello,

I'm trying to install rockbox on my sansa e260 v2 because it's no longer working properly and I thought I might as well try rockbox before chucking it out.

The problem is that I can charge it fully, but then it shuts down after some 10 minutes or so... Then it won't even open at all until I plug it back into the computer. The "low battery" message doesn't even show, it just looks dead.

Anyways, I got Rockbox utility and double clicked. It opens up and I get this message:
Configuration error: Your configuration is invalid. This is most likely due to a changed device path. The configuration dialog will now open to allow you to correct the problem.
I click OK.
I click Autodetect.
I get this message:
Fatal error: Unless you changed this installation will fail!

I don't understand this message at all! What does it mean? I thought maybe it had something to do with the USB mode.. Problem is, I can't find where to change USB mode on my player. I went through all the settings but I still can't find it. I'm not even sure this is really the problem.

So my question is, what do I do next?

BTW: My computer runs Ubuntu 10.04 LTS - the Lucid Lynx
but I have a virtual machine with Windows 7 if that can be any help..

I don't understand this message at all!

This means that your configuration is invalid, as the message says. There are various reasons for an invalid configuration. Since you're using Rockbox Utility for the first time it hasn't been configured. Rockbox Utility opens up the configuration dialog, which shows the device selection. It is mandatory to have the device configuration configured, and when running it for the first time this obviously can't be the case. To make life easier there's a big "autodetect" button at the bottom which in most cases gets things right. If it can't detect your player completely you'll get a message about that and can do the missing configuration manually. Note that autodetection will not select a player you don't have, so it's perfectly safe (and highly recommended!) to use it and only fill in things manually if it tells you about problems.

Ok, so I seem to understand that I need to indicate to Rockbox Utility where my device is in the filesystem by using the browse button, effectively replacing the autodetect function. Is that right? How can I find this information? I looked in the /media and /media/external folders but there's nothing in there. I can transfer songs fine through Rhythmbox, but I don't know where Rhythmbox found it..

edit
I don't know if this can help:

->lsusb
->Bus 003 Device 004: ID 0781:7422 SanDisk Corp. Sansa E200 series v2 (mtp)

Notice it says MTP. I tried changing to MSC on the device, but I never found out how. I'm supposed to have a "USB Mode" option under "Settings", but I don't. Any idea why?
