Why? I use the USB cable pretty often for transferring files and it simply works, with several Android devices of different brands. After all, WiFi is often very slow.
I began using USB for everything, cameras, phones. They all worked; KDE pop-up and mass transfer protocols.
The downside seemed to be that it sucked the battery in the camera or phone. I do not know why.
I understand that only on those devices that can not charge via USB cable, so not on phones. It happens on my Nikon D3200: it powers the USB from the battery. It can not charge the battery from USB charger, meaning I can not charge it on the car.
Now, I use a card reader. That's easy enough with the cameras - almost - since they exclusively use the card for storage. With the phone I need to transfer the relevant items to the card; not a big deal. Yes in come cases I can set the application to store on the card, but not all.
My phone no longer sees the card. I think it is the connections. :-//
The 'almost' is that with the older Canon cameras they use CF cards rather than SD or microSD, and my card reader doest handle CF cards, so I have to tether-upload. Then recharge the battery.
Huh. I just looked: my card reader has a CF slot (but I don't have any). It is a Trascend TS-RDF8K for USB 3 and 2. -- Cheers / Saludos, Carlos E. R. (from 42.2 x86_64 "Malachite" at Telcontar)
