sansa e260r usb stereo not working

[RWB44]

I just installed RB on my sansa e260r and everything is working great except my car stereo won't see the device via usb. This used to work with the stock sansa OS, now when connected using RB OS it says empty list. I am using the latest build 3.13 and just can't figure out how to get this working.

Nobody has any help to offer or experienced this issue?

Without knowing details it is impossible to say anything useful.

What details are needed? I have a 2012 Challenger with the stock radio. Prior to installing Rockbox, the e260r with the stock sansa software was able to plug into the usb port and play music on the radio. I could see all the artist and albums and play music without a problem. Now since installing the Rockbox software and plugging into the same usb port, the radio now says device list empty. If I hold any button on the e260r player, while plugging in the usb cable, to access the Rockbox menu's (per the Rockbox manual) then it doesn't even see the device. So plugging into the usb normal shows an empty list, plugging into the usb while holding any button on the e260r doesn't allow the radio to recognize the device.

Does your stereo work in MSC mode or MTP mode for the stock firmware?

[RWB44]

How would I find that out?

[RWB44]

So according to Sandisk:

e200R - PlayforSure is MTP and Rhapsody is MSC

So this would work using MSC as I've never changed the device to PlayforSure. Is the Rockbox software using MTP then? Is there a way to make it use MSC?

So this would work using MSC as I've never changed the device to PlayforSure.

I think MTP is the default, so you wouldn't have to change it.  Probably worth checking which modes actually work in your stereo.

Is the Rockbox software using MTP then? Is there a way to make it use MSC?

No, rockbox doesn't support MTP, only MSC.

Ok, I've verified that my e260r is in Rhapsody mode (MSC) and works with my stereo when using the stock Sansa e260r software. So what would cause this not to work when using the Rockbox software? The reason I need/want to use the Rockbox software with my stereo is that I added a 16gb microSD card to the e260r and the stock sansa software won't recognize it, yet the Rockbox does and works great with everything but the car stereo.

Sounds like you're out of luck.

How does that make any sense? MSC works on sansa but not on rockbox?!?!?!?

[saratoga]

MSC works on sansa but not on rockbox?!?!?!?

That is what you said above, yes. 

[RWB44]

I could be wrong but MSC is a standard format, it's not like the different variants of bluetooth. So again how is this possible???

[gevaerts]

There are two things to try that might make a difference:

* disable HID. The MSC/HID combination is not very common, and I wouldn't be surprised at all if it trips up some systems
* enable the "USB Hide Internal Drive" setting. I doubt this will help if the OF works, but car audio systems have been known not to like USB devices with more than one disk.

[RWB44]

Ok, I will try those 2 things here shortly. Are both the "disable HID" & "USB hide internal  drive" settings within the Rockbox system settings?
