iPod Nano 2G, rb 3.10 - USB not working

[fray]

Hey,

I have installed the latest stable version for iPod nano 2G, v. 3.10. Unfortunately, USB still does'nt work for me with this release.
When I plug it in, my syslog shows error similar to this:

Code: [Select]

Jul 11 12:14:55 Laser kernel: [  338.748820] xhci_hcd 0000:00:14.0: Timeout while waiting for address device command
Jul 11 12:14:56 Laser kernel: [  338.952692] xhci_hcd 0000:00:14.0: ERROR: unexpected command completion code 0x18.
Jul 11 12:14:56 Laser kernel: [  339.156532] usb 3-1: device not accepting address 10, error -22
Jul 11 12:14:56 Laser kernel: [  339.268443] usb 3-1: reset high-speed USB device number 10 using xhci_hcd

However, address and error are different. One time it actually worked and I could acces the filesystem.
I have uploaded two syslogs of failed usb connections here: http://pastebin.com/ubRLnbRk and here: http://pastebin.com/uJB6F3Dy.
Don't know if it is relevant, but I am on Linux Mint 15.
Is there anything I can do?

Any hint is gretly appreciated
