I want to downgrade the speed of USB 2.0 ports from High speed to full speed (USB1.0) in linux. I have tried many linux commands like "companion", "unbind". Therefore, I am not sure if the hardware can support this downgrade or not. The following figure from the datasheet shows it can support it, but it is not clear for me how to do it.
In this case, if you are trying to use USB devices that run at 1.0, the device should be recognized automatically at that speed without configuring anything, however, I’m not sure if this is the case in Linux but if it is not, you can post your question at:
