Seeking Datasheet/Pinout for Logitech USB Microcontroller (P/N: 361330-B000 RTH0200)

[Lahaie]

Hey everyone,

I’ve been stuck trying to reverse-engineer a Logitech device and need help identifying a microcontroller. The IC is labeled:
Logitech 361330-B000 RTH0200 5B294Q1 L5480

What I’ve tried:

• Searched DatasheetCat, Octopart, and Logitech’s official support (no luck).
• Checked GitHub repos and Hackaday projects for similar Logitech teardowns.
• Traced PCB connections but need clarity on USB D+/D−, power, and GPIO pins.

Questions:

1. Does anyone have a datasheet or pinout diagram for this IC?
2. Are there known debug interfaces (e.g., SWD, UART) on this chip?
3. Alternative approach? (e.g., sniffing USB HID descriptors?)

This is for a custom driver project, and any pointers would save my sanity!

Afaik Logitech doesn't make chips. Therefore the Logitech-labeled chip is very likely a custom programmed version of another commercial controller. It is very unlikely that information on the chip and the custom programming is available outside Logitech
