This category compiles official and legacy Atmel USB drivers for connecting and programming Atmel/Microchip USB-enabled hardware. Available downloads include AVRISP mkII and Atmel-ICE interface drivers, SAM‑BA bootloader (USB CDC/DFU) drivers, USB DFU and HID class drivers, CDC/ACM virtual COM port drivers, and WinUSB/libusb-compatible packages for custom applications. Each driver page lists supported device models, OS builds and release notes.
Download and installation: select the package for your operating system, download the signed installer or ZIP archive, then run the installer or extract files and update the driver via Device Manager (Windows) or use package manager/udev rules on Linux. macOS users will find guidance for virtual‑COM and user‑space drivers. Reboot and verify firmware/bootloader compatibility if a device is not recognized.
Compatibility and troubleshooting notes cover 32/64‑bit Windows, Linux kernel versions, and macOS restrictions; checksums and step‑by‑step install instructions are provided with each download.
