comment "USB Device Class drivers"

config OBSOLETE_OSS_USB_DRIVER
bool "Obsolete OSS USB drivers"
depends on USB && SOUND
help
This option enables support for the obsolete USB Audio and Midi
drivers that are scheduled for removal in the near future since
there are ALSA drivers for the same hardware.
Please contact Adrian Bunk <bunk@stusta.de> if you had to
say Y here because of missing support in the ALSA drivers.
If unsure, say N.
config USB_AUDIO
tristate "USB Audio support"
depends on USB && SOUND && OBSOLETE_OSS_USB_DRIVER
help
Say Y here if you want to connect USB audio equipment such as
speakers to your computer's USB port. You only need this if you use
the OSS sound driver; ALSA has its own option for usb audio support.
To compile this driver as a module, choose M here: the
module will be called audio.
config USB_MIDI
tristate "USB MIDI support"
depends on USB && SOUND && OBSOLETE_OSS_USB_DRIVER
---help---
Say Y here if you want to connect a USB MIDI device to your
computer's USB port. You only need this if you use the OSS
sound system; USB MIDI devices are supported by ALSA's USB
audio driver. This driver is for devices that comply with
'Universal Serial Bus Device Class Definition for MIDI Device'.
The following devices are known to work:
* Steinberg USB2MIDI
* Roland MPU64
* Roland PC-300
* Roland SC8850
* Roland UM-1
* Roland UM-2
* Roland UA-100
* Yamaha MU1000
To compile this driver as a module, choose M here: the
module will be called usb-midi.
config USB_ACM
tristate "USB Modem (CDC ACM) support"
depends on USB
