Hardware sometimes restricts how software can manage device configurations,in ways that may prevent implemention ofmulti-function devices,multi-configuration ones,or certain standard USB Device Class specifications.
At this writing there are several public 'gadget drivers',each implementing a single common USB function so itwill work with virtually any USB peripheral controller. The gadget API does support such drivers.
You should plan on testing these in conjunction withthe controller driver and system board you'll be using. This driver can interoperate with hosts running Linux, MS-Windows, and other operating systems; if the OS can talk to a cable modem, it probably supports this driver.
To do this, it supports several modes:. To better support DHCP, ZCIP, and related network autoconfiguration, you'll want to manage Ethernet addresses so that each peripheral reuses the same unique address every time it boots.
You should assign those addresses using a registered IEEE company id; this will also make the device appear to Linux hosts as an 'ethN' interface, not as 'usbN'. A solution that's simpler to configure might use the USB-IF Still Image Capture Device class specification, whichpresents a hierarchical filesystem as well as some operationsspecific to cameras setting focal length, shutter speed, etc and capturing images.
At this writing, there is no Linux kernel implementation of PTPon either host or peripheral side. However, there are host side user-mode implementations, suchas gPhoto2. Other controller and gadget drivers are in development,but are unreleased or not published here.
Examples that have seen some degree of light include:. Yes, please! Bug fixes, gadget drivers especially 'class' drivers ,and new USB device controller drivers will all be of interest. Discussions, patches, and similar work should beon the linux-usb-devel mailing list for now.
This work has been supported by patches, feedback, bug reports,hardware, and other contributions from many groups and individuals. Select the. From Wikipedia, the free encyclopedia. My computer is missing this driver. Download in other formats. Skip to content. Many developers have asked about easy ways to start working with this API. Otherwise, a Net PCI card lets you work on a standard PC, developing ordebugging gadget drivers on computers you may already own.
Parts of the Framework The API standardizes a platform-neutral boundary betweentwo software layers,but the software stack usually has several higher layers. Different controller hardware will need different drivers, which may also need board-specific customization. These provide a software 'gadget' device, visible in sysfs. You can think of that device as being the virtual hardware to which the higher level drivers are written.
Other operating systems use other names for this component, perhaps labeling the API plus its libraries as a 'Platform Independent Layer' and its implementation as a 'Platform Specific Layer'. Gadget Drivers use that gadget API, and can often be written to be hardware-neutral.
Certain hardware facts need to affect the implementation of configuration management parts of ep0 logic. Those issues may be handled at various points: build time, initialization time, or run time. For example, some controllers have more endpoints than others, many don't support high speed or isochronous transfers, and sometimes endpoints have fixed configurations.
A gadget driver implements one or more 'functions', each providing a different capability to the USB host, such as a network link or speakers. Other operating systems use other names for this component, such as a 'USB Client driver'. These are directly analagous to host side 'interface drivers', except for multi-function 'composite' gadget drivers. These generate and consume the data that the gadget driver transfers to the host through the controller driver.
There will often be several such layers, perhaps including user mode components. Again, this is directly analagous to what host side drivers do, though producer and consumer roles are probably reversed. A set of procedural directives and guidelines published in august by the u.
