Force use of USB1.1 instead of USB2.0

  • Hello,

    we plan to replace the NetDCU10 with the NetDCUA5. Our hardware is not designed for USB2.0 so want to stay with USB1.1. We are using linux. Is it possible to enforce the the use of USB1.1 instead of USB2.0?

  • Yes, the following patch should achieve this. Just go to the top directory of your Linux source code tree, copy the patch there and apply it with

    1. patch -p1 < Force-USB-To-FullSpeed.patch

    Then recompile your kernel. Now USB should be restricted to Full-Speed instead of High-Speed.
