USB Passthrough Firmware Development for RP2040 -- 2

@jakubf41

I can help develop the USB HID passthrough firmware for your Feather RP2040 with USB Host support. I have experience with RP2040 development, TinyUSB host/device stacks, and USB HID descriptor handling. Approach: -Configure the RP2040 to operate as a USB host for HID devices using TinyUSB. -Implement a HID passthrough layer that forwards reports from connected devices (keyboard, mouse, etc.) to the computer. -Support up to 5 HID interfaces, ensuring stable enumeration and device handling. -Modify USB descriptors so the iSerialNumber is removed or replaced, preventing it from being passed through. -Test with generic HID devices to ensure compatibility without device-specific drivers. Deliverables: -Stable RP2040 firmware ready to flash -Clean source code with build instructions -Brief documentation explaining the passthrough logic and descriptor handling I can complete the work quickly and ensure the firmware runs reliably on your hardware. Best regards

Hello, I can develop this on the Feather RP2040 using TinyUSB host/device stacks, with the board acting as a USB host for HID input and presenting a clean HID device interface to the connected computer. My approach would be to handle HID report parsing and forwarding at the firmware layer, support multiple enumerated HID interfaces, and explicitly sanitize USB descriptors so the upstream device serial number is never passed through. I would keep the implementation generic so standard mice, keyboards, and similar HID-class devices work without vendor-specific drivers. I’m comfortable with RP2040 USB work, descriptor-level handling, and embedded debugging for stability under repeated connect/disconnect cycles. Deliverable would be working firmware, tested passthrough behavior, and clean source code for future maintenance. Best regards.

Hello, I’m Benedict. I’ve reviewed your USB Passthrough Firmware project for Feather RP2040 with USB Host support and I’m genuinely excited about delivering a robust, multi-HID passthrough solution. With hands-on experience in RP2040 development, USB Host/Device stacks (TinyUSB), HID protocol handling, and designing firmware that cleanly forwards descriptors and data, I can build a stable, driver-agnostic passthrough that supports at least five HID interfaces, while ensuring the serial number is not exposed to or altered for the host. I will implement a clean pass-through path from HID devices to the PC, isolating the host side so each device can operate without requiring device-specific drivers. The plan is to: 1) set up a TinyUSB-based host stack on the Feather RP2040, 2) implement multi-HID interface tracking with robust pairing and timeouts, 3) modify descriptor handling to strip or replace iSerialNumber, 4) ensure a reliable, low-latency data path with careful buffering, 5) provide a repeatable CI workflow and a minimal test suite to validate mice, keyboards, and generic HID devices. I’m prepared to align the implementation with your hardware constraints and can tailor the firmware for a clean, production-ready release. I’d appreciate the opportunity to discuss timelines, your preferred TinyUSB version, and any constraints around USB power or host-controller resources. Best regards, Benedict

Hi, I have experience with RP2040 firmware and USB stack work, and I can develop the Feather RP2040 firmware to act as a USB host with reliable HID passthrough to a connected computer using TinyUSB or a similar approach. I understand the key parts here are stable handling of generic HID devices, clean descriptor management, support for multiple HID interfaces, and making sure the original iSerialNumber is not forwarded or exposed. I can build or modify the firmware so mice, keyboards, and other standard HID devices are passed through properly without device-specific drivers, then test for stability and correct behavior under real usage. The extra $20 is fine, and I’m ready to start.

Hello, I have experience developing firmware for RP2040 and working with USB stacks such as TinyUSB, including HID devices and descriptor handling. I can implement firmware for the Feather RP2040 that acts as a USB host for HID devices and forwards HID reports to the connected computer. The firmware will also filter or replace the iSerialNumber descriptor so the original device serial is not exposed. Implementation will be based on TinyUSB and designed to work with generic HID devices (keyboard, mouse, etc.). Estimated timeline: 3–4 days.
