I am trying to connect my android galaxy S2 device using MTP. I have tried all the methods in http://askubuntu.com/a/247046/112042, but I can not access my device file system using MTP.

Here is the message that I get, each time I try to connect my device.

Mar  3 10:17:15 g-e420-45 kernel: [ 3021.224138] usb 2-1.4: new high-speed USB device number 20 using ehci_hcd
Mar  3 10:17:20 g-e420-45 kernel: [ 3026.309361] usb 2-1.4: can't set config #1, error -110

And when I disconnect, I get the following message.

Mar  3 10:18:32 g-e420-45 kernel: [ 3097.981202] usb 2-1.4: USB disconnect, device number 20
Mar  3 10:18:32 g-e420-45 kernel: [ 3098.184342] usb 2-1.4: new high-speed USB device number 21 using ehci_hcd
Mar  3 10:18:32 g-e420-45 mtp-probe: checking bus 2, device 21: "/sys/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.4"
Mar  3 10:18:37 g-e420-45 mtp-probe: bus: 2, device: 21 was not an MTP device
Mar  3 10:18:37 g-e420-45 kernel: [ 3103.273890] usb 2-1.4: can't set config #1, error -110

Could someone help me understand whats going wrong?

UPDATE:

I was using CyanogenMod 10.2 when I noticed the above error, so I updated to the latest nightly ROM available and now I see the following error when I try to connect as MTP,
