Make Rockbox mount SD and not Internal memory (car deck USB)

[mrbryan]

When I connect the player in my car, it mounts only the 4gb internal memory instead of my larger SD card.

Does anyone know how to make the device mount the SD card only?

Rockbox should expose both storage devices as UMS.  It doesn't appear that much  can be done about forcing your car stereo to only mount one or the other.

Your car probably can't handle multiple LUNs.

You could compile a special build that only exposes the card slot over usb. To do that, add a line saying

Code: [Select]

#define HIDE_FIRST_DRIVE

near the top of firmware/usbstack/usb_storage.c

Of course, this will have the result that you can't access the internal memory from the PC anymore either, unless you keep the changed build somewhere else on the player and RoLo it when needed...

Or you could look at what HIDE_FIRST_DRIVE achieves (it's rather simple) and add a setting for this.

I think that in this situation I'd just get a cheap SD card reader though.

Edit: using HIDE_FIRST_DRIVE may lead to some unexpected behaviour if the SD card is plugged or unplugged during the USB connection. It was originally meant as a quick hack for debugging, and it doesn't take inserted/ejected status into account properly.

Cool thanks I may try that

this would be epic if a setting for this were commited as a feature...
the majority of my music is on my microsd, and in a my bmw it only mounts the fist drive(internal storage)

+1, I totally agree.

+1, I totally agree.

Such a shame then that all the "yeah, this would totally be awesome" posts don't mean anything if those people aren't prepared to actually do the work

A fix for this was suggested by gevaerts several posts ago.

Yeah, but not all of us are developers here so we do what we can, i.e. show our interest in having such a feature.
The fix gevaerts suggested above is a temporary solution indeed, but it's not really handy for an everyday user. That's why an option in the USB driver would be actually welcome.

Saint's point is that saying "+1" doesn't do anything, other than perhaps annoy a few people who might interpret it as asking someone else to do the work for you. You would be better off not posting at all if you have nothing concrete to add.

Anyone who reads this thread, whether they are a developer or just someone who might write a patch, already knows by reading it exactly what the problem is, and gevaerts gave a big pointer to anyone on how to implement a setting. If someone with the ability feels like doing it they will do it, with or without your +1.

I would do this myself if I had a player with an SD slot, but I don't, and my motivation to work on something that I'd be dependent on someone else for all testing is not very high. Someone who owns the player in question is always more likely to do something about a player-specific issue.
