Options
- AYou need to rebuild the kernel.
- BYou need to upgrade the kernel
- CYou need to load the USB modules for your existing modular kernel.

Explanation
Linux kernel 2.0.36, released in 1998, predates widespread and stable USB support in the kernel, thus requiring a kernel upgrade for modern USB device functionality.
Common mistakes.
- A. While rebuilding might be an option with a newer kernel source, the fundamental issue with 2.0.36 is the lack of core USB support, which a rebuild alone won't provide.
- C. Even if the kernel was modular, the necessary USB drivers and core USB stack would likely not exist or be stable in the 2.0.36 kernel version to simply load as modules.
- D. USB support did eventually become available in Linux, but not reliably in the 2.0.x series.
