Hi Cheshire, I wanted to ask about the usb host interface for usb devices, where did you find about the d+,d- input and output (for tx and rx) and the enable?

Thanks , Sally

Hi,

I am not entirely sure what you mean, but here are some pointers:

Cheshire instantiates SpinalHDL's USB OHCI controller with four ports. This OHCI controller is compatible with existing drivers in Linux. For details on how this IP is designed, please see its documentation.
The OHCI standard can be found here in case you have questions about the protocol itself.

I am closing this for now; feel free to reopen in case you have questions regarding Cheshire.
