Richard Hughes 3dc49c21b5 dfu: If no DNLOAD timeout is set assume a default value 
This is probably a case where the device does not adhere to the specification.

Some hardware may be deliberately setting DNLOAD timeout to 0ms, and this patch
will make each request 5ms slower. This is probably a good tradeoff for having
most hardware 'just work' without a quirk entry.

Based on a patch by Zack Lee Yi Wei <zack_lee@chicony.com>, many thanks.

DFU Support

Introduction

Device Firmware Update is a standard that allows USB devices to be easily and safely updated by any operating system.

Firmware Format

The daemon will decompress the cabinet archive and extract a firmware blob in DFU or DfuSe file format.

This plugin supports the following protocol IDs:

  • org.usb.dfu
  • com.st.dfuse

GUID Generation

These devices use the standard USB DeviceInstanceId values, e.g.

  • USB\VID_273F&PID_1003&REV_0001
  • USB\VID_273F&PID_1003
  • USB\VID_273F

Vendor ID Security

The vendor ID is set from the USB vendor, for example USB:0x0A12

Quirk use

This plugin uses the following plugin-specific quirks:

Quirk Description Minimum fwupd version
DfuFlags Optional quirks for a DFU device which doesn't follow the DFU 1.0 or 1.1 specification 1.0.1
DfuForceVersion Forces a specific DFU version for the hardware device. This is required if the device does not set, or sets incorrectly, items in the DFU functional descriptor. 1.0.1
DfuForceTimeout Forces a specific device timeout, in ms 1.4.0

External interface access

This plugin requires read/write access to /dev/bus/usb.
