I recently acquired two slotRadio players that work fine, except that they are not in any way recognized by my Mac when connected to a USB port. I got them as part of a lot of various Sansa players and the seller had said that they “Cannot Connect to PC”, so it’s not a Mac problem. (I also have XNJB for MTP connections. Neither that, the Finder, the Terminal nor System Profiler recognize them in any way.)
However, the players, when physically connected, show an animation that indicates an active connection.
Can anything be tried to get a computer to recognize these?
Aside from firmware upgrades, is there anything important that can’t be done by just moving the microSD[HC] card between the computer and the player?
