Rooted Kindle Fire - Mounting Filesystem from Ubuntu

Question

I have a first gen Kindle Fire that has been flashed with Android 4.0.4 (hashcode's of course).

The device was rooted using my thoshiba NB305 netbook running ubuntu 10.04 (Lucid).

While the original OS was still installed, I could mount the kindle's filesystem over a usb connection using

 mount -t ext3 /dev/sdc /mnt/kfire

Now I'm trying perform another rooting operation from the same laptop, to upgrade android to 4.2.2, and cannot get the kindle's file system mounted with this command.

I checked dmesg and the devices is still being detected as SCSI device on /dev/sdc

 sd 11:0:0:0: [sdc] Attached SCSI removable disk

however, a

 ls -l /dev/disk/by-id/

reveals that

 usb-Am_File-CD_Gadget_0123456789ABCDEF-0:0 -> ../../sdc

The thing is, mount isn't even detecting that a device is present at /dev/sdc, I simply get the error

 mount: no medium found on /dev/sdc

I'm not sure how to mount a usb-Am_File-CD_Gadget, or why I'm not at lest getting a "wrong filesystem type" error from mount.

Also, the kindle is not showing up when running

 adb devices

and so figured I needed to mount it in order for adb to be able to see it. However, I just tried my LS970, and its showing up in adb devices, but also cannot be mounted with the above command (or mtpfs -o allow_other /mnt/kfire).

So, I'm looking to get the kindle discovered and communicating with adb first and foremost (I thought mounting was required for this, but apparently isn't).

I found this article to be potentially helpful, but still need to give it a through reading:

Any help is much appreciated, Thank you.

Turns out it was the micro-usb cable I was using to connect the kindle to my laptop.

Once I found my uber quality ASUS cable, progress began...

Now the OS atleast properly detecting the device, and loading it as a mass USB storage device.

dmesg:

[ 5516.756143] usb 1-1: new high speed USB device using ehci_hcd and address 125

[ 5522.433234] sd 4:0:0:0: [sdc] Attached SCSI removable disk

However, adb devices now gave:

List of devices attached 
????????????    no permissions

to get ADB to properly list the device, and be able to connect to it, please see this solution on SO:
