What is the intended use of the USB HID feature?

Thanks,

Could you be more specific about what you're asking?

There's no "intended" use. It provides media-button like controls, which you can either use as such or if your OS / applications allow, map them to other functions.

I don't think I need to be more specific. I believe that you have answered my question.

Do I understan you to say that the RockBoxed media player can be used as a USB input device (key-mapped) for the Windows PC? especially a media app?

Thanks,

Basically, that's one of the goals yes. I'm not sure as to its current status (haven't tried it out myself) but it should be possible to adjust volume, pause and resume playback and so in a program on your PC by pressing the buttons on an attached MP3 player. This will only be able to work on certain ones though (those with software USB).

And it works brilliantly.  It sends the same commands as used by the buttons on a multimedia keyboard (I think - I'm sure someone will correct me if not , so anything that works with those should work with this.

i'm afraid i don't get this new usb hid stuff. after switching to r21065, anytime i connect my sansa e260 with my xp machine, i am asked to install drivers which i deny. then i'm able to play stop pause etc. in foobar using my e260, but not with the according keys, only with the help of the debug menu. i find this rather annoying. is there any way to configure the sansa to connect as a disk in rb again? or will i have to revert to before this hid commit?

[Llorean]

It should still show up as a disk as well. I'm using 21085 without any problems at all. It shows as both a portable disk and works as a media controller. No driver prompt either.

You should probably update first, see if that fixes it. As always, we ask that you not post about problems you're having with older versions.

Now all I want is a Sansa e200 skin for WinAmp.

r21133
The Hard drive F: is my external USB drive which works fine. Normally the Sansa would be listed as removable drives G: and H:, but since the commit, it doesn't show up at all. The Rockbox media player device is shown, when i try to automatically install the new hardware. this dialogue pops up any time i plug in the sansa.
It also is not present in the Hard drive Manager.

If you can get to the debug menu, you're not entering USB mode at all.

Are you using an official, unmodified build? It sounds like the standard behaviour when someone's holding Select and preventing USB connection.

[BdN3504]

as i stated, i use r 21133. i have not modified anything.
i connect the device as i did before: i plugin the cable when it's shut off, then wait for it to boot into rockbox, not touching any buttons. i can still manage to access the original fw using |<<.
my start screen is set to main menu.

[Llorean]

What happens if you turn it on, wait for it to boot, then plug in the cable once you're safely inside Rockbox?

[BdN3504]

i get exactly the same behaviour. The player shows the usb sign, windows recognizes the player has been plugged in and asks me to install a driver.

[Llorean]

Considering that nobody else is experiencing this with e200s, is there anything else about your situation?

Your player is behaving exactly as if "select" were held down during USB insert.

[gevaerts]

Is this with an official build? Also, why did you deny driver installation?
