I think bcharge from barry is the problem here
Do you use 0.15 from Lucid repos? I had the same problem with this version.
[10732.836712] usb 2-1: usbfs: interface 1 claimed by usb-storage while 'bcharge' sets config #1
[10733.948158] usb 2-1: reset high speed USB device using ehci_hcd and address 5
I removed it
and installed Barry 0.17.1 for Ubuntu 10.04 with libbarry0, barry-util, barrybackup-gui, libbarry-dev and opensync-plugin-barry_0.17-1.
sudo apt-get remove barrybackup-gui opensync-plugin-barry barry-util libbarry0 libbarry-dev
It works like a charme.
