List all connected devices in table format:

ffx target ssh -- print-input-report list

List devices in CSV format:

ffx target ssh -- print-input-report list --output csv

List devices in JSON format:

ffx target ssh -- print-input-report list --output json

Read descriptors for all connected devices:

ffx target ssh -- print-input-report get-descriptor

Read descriptor for a specific device instance:

ffx target ssh -- print-input-report get-descriptor --instance 000

Read descriptor in JSON format filtered by vendor and product ID:

ffx target ssh -- print-input-report get-descriptor --vendor 0x18d1 --product 0x5036 --output json

Continuously stream input reports from all devices:

ffx target ssh -- print-input-report read

Read 5 reports from a specific device instance:

ffx target ssh -- print-input-report read --instance 000 --num-reads 5

Read reports in JSON format filtered by vendor and product ID:

ffx target ssh -- print-input-report read --vendor 0x18d1 --product 0x5036 --output json
