Hello.
I installed today the new 3.3 version (upgrade from 3.2) on my iRiver H10 6GB UMS player and now I have this "USB mode". I don't really need it, because before, with previous RockBox versions, if I plug the cable while the player is OFF, and then I turn the player ON, I get into USB (emergency USB?) mode. If I plug the cable while the player is ON, then it just started to charge, but will continue to play. So I can decide whether I want to use USB mode or CHARGE + PLAY mode by pluging cable while player ON or OFF. Now when I plug the cable while playing, I go in USB mode, and there is no way (at least I din't see a way) to leave the player playing. So in my car when I decide to use the cable for charging it will go into USB mode and I will not have music.
I didn't see an option to switch this new "USB mode" on and off.
That's why I had to downgrade to v3.2 which seems perfect to me.
Any opinions?
