Thanks for all the advice offered recently. The simple method which works is
(1) enable 'fuse-fs' in kernel ; (2) re-merge Kio-extras with USE="mtp" ; (3) wake phone, plug in USB connection at both ends ; (4) on phone, tap 'allow' to access data ; (5) on Gentoo, Dolphin shows 'SAMSUNG_Android' under 'Devices' ; (6) goto 'Internal storage/DCIM/Camera' ; (7) view w Gwenview, which offers to save the photo as your choice. This relies on KDE's internal use of Fuse, which simplifies actions. The device appears as /dev/libmtp... which is a symlink to /dev/bus/003/009 (or similar), which is not a block device & can't be mounted via 'mount'. KDE uses some version of Fuse to access it & offer its contents. HTH others. -- ========================,,============================================ SUPPORT ___________//___, Philip Webb ELECTRIC /] [] [] [] [] []| Cities Centre, University of Toronto TRANSIT `-O----------O---' purslowatcadotinterdotnet
