|
|
USB is a host/device protocol, organized with one host (such as a
|
|
PC) controlling up to 127 peripheral devices.
|
|
The USB hardware is asymmetric, which makes it easier to set up:
|
|
you can't connect a "to-the-host" connector to a peripheral.
|
|
|
|
Linux can run in the host, or in the peripheral. In both cases
|
|
you need a low level bus controller driver, and some software
|
|
talking to it. Peripheral controllers are often discrete silicon,
|
|
or are integrated with the CPU in a microcontroller. The more
|
|
familiar host side controllers have names like "EHCI", "OHCI",
|
|
or "UHCI", and are usually integrated into southbridges on PC
|
|
motherboards.
|
|
|
|
Enable this configuration option if you want to run Linux inside
|
|
a USB peripheral device. Configure one hardware driver for your
|
|
peripheral/device side bus controller, and a "gadget driver" for
|
|
your peripheral protocol. (If you use modular gadget drivers,
|
|
you may configure more than one.)
|
|
|
|
If in doubt, say "N" and don't enable these drivers; most people
|
|
don't have this kind of hardware (except maybe inside Linux PDAs).
|
|
|
|
For more information, see <http://www.linux-usb.org/gadget> and
|
|
the kernel documentation for this API.

|
|
help
|
|
Many controller and gadget drivers will print some debugging
|
|
messages if you use this option to ask for those messages.
|
|
|
|
Avoid enabling these messages, even if you're actively
|
|
debugging such a driver. Many drivers will emit so many
|
|
messages that the driver timings are affected, which will
|
|
either create new failure modes or remove the one you're

trying to track down. Never enable these messages for a

production build.

Some of the drivers in the "gadget" framework can expose

debugging information in files such as /proc/driver/udc
|

files may help when you're troubleshooting or bringing up a
|

driver on a new board. Enable these files by choosing "Y"

|
|
help
|
|
Some devices need to draw power from USB when they are
|
|
configured, perhaps to operate circuitry or to recharge
|
|
batteries. This is in addition to any local power supply,
|
|
such as an AC adapter or batteries.
|
|
|
|
Enter the maximum power your device draws through USB, in
|
|
milliAmperes. The permitted range of values is 2 - 500 mA;
|
|
0 mA would be legal, but can make some hosts misbehave.
|
|
|
|
This value will be used except for system-specific gadget
|
|
drivers that have more specific information.
|
|
|
|
config USB_GADGET_STORAGE_NUM_BUFFERS
|
|
int "Number of storage pipeline buffers"
|
|
range 2 256
|
|
default 2
|
|
help
|
|
Usually 2 buffers are enough to establish a good buffering
|
|
pipeline. The number may be increased in order to compensate
|
|
for a bursty VFS behaviour. For instance there may be CPU wake up
|
|
latencies that makes the VFS to appear bursty in a system with
|
|
an CPU on-demand governor. Especially if DMA is doing IO to
|
|
offload the CPU. In this case the CPU will go into power
|
|
save often and spin up occasionally to move data within VFS.
|
|
If selecting USB_GADGET_DEBUG_FILES this value may be set by
|
|
a module parameter as well.
|
|
If unsure, say 2.

CDC EEM is a newer USB standard that is somewhat simpler than CDC ECM

EEM are designed for different applications. The ECM model extends

the network interface to the target (e.g. a USB cable modem), and the

|
EEM model is for mobile devices to communicate with hosts using

ethernet over USB. For Linux gadgets, however, the interface with

the host is the same (a usbX device), so the differences are minimal.

The Function Filesystem (FunctionFS) lets one create USB

composite functions in user space in the same way GadgetFS
|
|
lets one create USB gadgets in user space. This allows creation

|
of composite gadgets such that some of the functions are
|
|
implemented in kernel space (for instance Ethernet, serial or
|
|
mass storage) and other are implemented in user space.

Both protocols can work on USB2.0 and USB3.0.

UAS utilizes the USB 3.0 feature called streams support.
