Description:
This file can be read and write.
The file can show/change the drd mode of usb.
Write the following string to change the mode:
- "host" - switching mode from peripheral to host.
- "peripheral" - switching mode from host to peripheral.
Read the file, then it shows the following strings:
- "host" - The mode is host now.
- "peripheral" - The mode is peripheral now.
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.
