Sansa Clip+ USB HID

[hamstarr]

Has anyone tried to enable USB HID mode on the sansa clip+? I noticed it is enabled for the non-plus sansa.

http://git.rockbox.org/?p=rockbox.git;a=blob_plain;f=firmware/export/config/sansaclipplus.h;hb=HEAD
http://git.rockbox.org/?p=rockbox.git;a=blob_plain;f=firmware/export/config/sansaclip.h;hb=HEAD (define HAVE_USB_HID_MOUSE)

Maybe there's a good reason for it not being enabled, I'd like to know


Edit:
To test it myself, I commented in the following line from \firmware\export\config.h:
-//#define USB_HAS_INTERRUPT
+#define USB_HAS_INTERRUPT
and rebuilt rockbox...

Guess what it didnt work, it connected, windows told me it failed to install the keyboard device.

What's strange is that
windows first detects a media device, changes to a keyboard, hid app crashes.
