I have just installed libmtp, and did a mtp-detect and got this:
stufkan@stufkan-desktop:~$ mtp-detect
Attempting to connect device(s)
usb_claim_interface(): Device or resource busy
LIBMTP PANIC: Unable to initialize device 1
LIBMTP PANIC: configure_usb_devices() error code: 7 on line 1686
Detect: There has been an error connecting. Exiting
Whats wrong? Its a creative zen micro i am trying to connect to

noone?
