USB and FireWire for Older iPods: Charging and Data Connections
Older iPods do not share one cable or power rule. Identify the generation and capacity, then check data transfer and charging separately.
Start with iPod generation. Original diagram by Things To Do Your Thing; facts are traced to G05-S1, G05-S2, G05-S3, G05-S4.
| Evidence | Documented connection detail | Caution |
|---|---|---|
| Third-generation, April 2003 | Apple lists FireWire and USB 2.0 and period computer requirements. (Apple release) | Period requirements are not current OS guidance. |
| 20/40 GB models, September 2003 | Apple documents those models and USB 2.0/FireWire connections. (Apple release) | Accessories may vary by configuration. |
| Fourth-generation, July 2004 | Apple says syncing and charging could use FireWire or USB. (Apple release) | Applies to this announcement’s generation. |
Two documented models: data and charging are separate
| Model | USB data | FireWire data | USB charging | FireWire charging |
|---|---|---|---|---|
| iPod (3rd generation) | Yes, with the split dock cable and supported software | Yes | No through the USB-only leg of the split cable | Yes; FireWire carries both sync and power |
| iPod mini (1st generation) | Yes, USB 2 with supported cable/host | Yes | Yes | Yes |
The third-generation row reflects the split cable documented in a period review: USB carries data while the FireWire lead supplies charge; FireWire alone can do both. Apple’s first-generation mini specifications and launch announcement document sync and charge over either supported connection. This comparison covers only these two models—do not apply it to another generation based on connector shape alone. (Stereophile; Apple mini specifications; Apple mini launch announcement)
Documented connection milestones. Original diagram by Things To Do Your Thing; facts are traced to G05-S1, G05-S2, G05-S3, G05-S4.
A plug that fits does not establish syncing support, and data support does not itself establish charging support. Eject through the documented software. Apple’s later iPod classic guide gives a USB setup sequence for that edition only. (iPod classic Quick Start)
No old iPod or current computer port was tested. See 3rd-generation iPod and iPod mini.
