Comment 7 for bug 803694

@Bilal Akhtar: I've just tried it, but without success. Even though doing it indeed changed the behavior of KDE into displaying my tablet as "Portable media device" instead of "Camera", and mtp-detect into detecting the device, although failing to actually connect to it, I cannot really use any means to get into the device's storage. Dolphin only shows directories, and has random errors when doing so. I have no write permissions and cannot even see files that I know that are there in the tablet.

I also noticed that issuing dmesg in terminal has those lines:
[ 2611.574532] cdc_acm 2-1.3:1.1: This device cannot do calls on its own. It is not a modem.
[ 2611.574604] cdc_acm 2-1.3:1.1: ttyACM0: USB ACM device
[ 2611.577736] usb 2-1.3: usbfs: process 2882 (mtp-detect) did not claim interface 0 before use

My tablet is a wifi-only version, so it cannot indeed be a modem. Could this have something to do with the bug I'm facing?

I am not very experienced, but I am willing to do some C hacking if I can help solve the bug by doing that. I just need a pointer to where to begin with it.
