1 Introduction

1.5.3 Host tool v1.3 (cfbdb79, windows build 64)

Bug fixes

• Correct doubled injector packet count reported by hw_info command
• Work around problems with libreadline 8.1
• Fix ”inject” command (may need firmware 1.08 for larger packets)
• Adjust maximum packet size capture limits

New features

• Latency tester feature
• Tab completion (if built with readline; dysfunctional on Windows)
• New options: --cmd, --run, --exit-on, --exit-timeout

1.5.4 Host tool v1.2 (ff97f53)

Updating to firmware 1.06 is recommended.

Potential incompatibilities and problems

• Firmware update is now invoked differently
• Changes to inject and disrupt command parameters

Bug fixes

• In Wireshark extcap mode, terminate properly if no packets were captured

New features

• Full support for firmware 1.06
• Slightly improved link status reporting
• Extend capabilities of inject and disrupt commands
• Change USB device name format and include device address (allows distinguishing multiple devices

connected to chained hubs)

• Accept device serial number as device name and report it via extcap to Wireshark
• Add quoting/escaping and named arguments to command parser
• Perform more parameter validation in command/option parser
• Unify PHY/port names to A/B/AB/none (a mix of conventions was used before)

1.5.5 Host tool v1.1 (686fe4f)

• Add ”speed” convenience command
• Improve capture stats log behavior
• Note that this used to be untagged in the public git repository

1.5.6 Host tool v1 (f5eed9c)

• Initial release
• Note that this used to be untagged in the public git repository
