kernel CONFIG flags

[giuliomoro]

Please enable
CONFIG_XENO_DRIVERS_RTIPC

Otherwise you cannot create pipes! (RTIPC is real-time-inter-process-communication).
Perhaps other things need to be enabled as well, check the 3.8.13 kernel config for hints on XENO flags to enable:
BelaPlatform/Bela#171 (comment)

[giuliomoro]

Also, please enable

# CONFIG_SND_VIRMIDI

and then at least these CONFIG_USB... (or perhaps all of them)

# CONFIG_USB_CONFIGFS_F_MIDI
# CONFIG_USB_CONFIGFS_F_HID
# CONFIG_USB_CONFIGFS_MASS_STORAGE

Note for self: go back to this when done https://forum.bela.io/d/44-usb-gadgets/4
