H340 charging issues and new behaviour that is strange.

I am still having the problem of no USB charging... but some other
interesting facts that might help and maybe someone may know what is going

well let's say my H340 is in that completely flat battery state where you
cannot start it up. the state where you would either put it right into the
AC power or stick it in USB for charging. As I have said, USB charging does
not work on my player at the moment so.... I put it in the AC power.

you would think then that it would go right into charge mode... from the
completely flat state... but it does not. it seems to boot into the iriver
firmware and move to the playing screen. in other words, starts up
normally. It won't go into charge mode unless I hold down STOP. If I do
that, sure it goes into charge mode... but it seems to be happier to stay in
normal Iriver play mode.

I then connected the USB cable and it went into USB connect mode and then
came up as a drive on my PC etc. so in other words, it is acting as if it
is not flat. or acting as if it does not like going to charge mode When it
was flat, it used to want to go into charge mode no matter what. now it
seems to do the opposite. Anyone seen this sort of thing or have any ideas.

I know this is now a problem that is really probably not to do with Rockbox
but maybe someone knows about the H340s and knows what is happening here.

One theory. Maybe my player is in some sort of state where the only way to
get it to charge is if you fully boot into Iriver firmware and then wait for
it to get to the playing screen and then hold down STOP. and in the case of
trying to charge via USB, it fails because it is too flat to ever get to the
stage where it is in the play screen, so you don't get the opportunity to
make it start charging before it dies and restarts. When plugged into power
only it can be made to charge (by holding down STOP) and that works ok
because, being connected to real power, it can boot up properly.

Hmm. any thoughts.
