Annotated Snippet
What: /sys/devices/platform/usbip-vudc.%d/dev_desc
Date: April 2016
KernelVersion: 4.6
Contact: Krzysztof Opasiak <k.opasiak@samsung.com>
Description:
This file allows to read device descriptor of
gadget driver which is currently bound to this
controller. It is possible to read this file
only if gadget driver is bound, otherwise error
is returned.
What: /sys/devices/platform/usbip-vudc.%d/usbip_status
Date: April 2016
KernelVersion: 4.6
Contact: Krzysztof Opasiak <k.opasiak@samsung.com>
Description:
Current status of the device.
Allowed values:
== ==========================================
1 Device is available and can be exported
2 Device is currently exported
3 Fatal error occurred during communication
with peer

What: /sys/devices/platform/usbip-vudc.%d/usbip_sockfd
Date: April 2016
KernelVersion: 4.6
Contact: Krzysztof Opasiak <k.opasiak@samsung.com>
Description:
This file allows to export usb device to
connection peer. It is done by writing to this
file socket fd (as a string for example "8")
associated with a connection to remote peer who
would like to use this device. It is possible to
close the connection by writing -1 instead of
socked fd.
Annotation
- Atlas domain: Support Tooling And Documentation / Documentation.
- Implementation status: atlas-only.
Implementation Notes
- This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
- Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
- Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
