Comment 5 for bug 1813429

The log has that error at 08:06:01, do you remember if that's the time where you saw the problem?

gvfsd[2501]: PTP_ERROR_IO: failed to open session, trying again after resetting USB interface
gvfsd[2501]: LIBMTP libusb: Attempt to reset device
kernel: usb 2-4: USB disconnect, device number 6
gvfsd[2501]: inep: usb_get_endpoint_status(): No such device
gvfsd[2501]: outep: usb_get_endpoint_status(): No such device
gvfsd[2501]: libusb_open() failed!: No such file or directory
gvfsd[2501]: LIBMTP PANIC: Could not init USB on second attempt

The log suggest that the lower level stack kernel/libmtp acted like if the device vanished and got plugged again. Are you confident the cable doesn't have a loose connection? Does copying from the same device/cable works fine from other computer (or ideally from the same computer on another OS)?
