- Say Y here if your system has a Dual Role Hi-Speed USB
- controller based on the DesignWare HSOTG IP Core.
- For host mode, if you choose to build the driver as dynamically
- linked modules, the core module will be called dwc2.ko, the PCI
- bus interface module (if you have a PCI bus system) will be
- called dwc2_pci.ko, and the platform interface module (for
- controllers directly connected to the CPU) will be called
- dwc2_platform.ko. For all modes(host, gadget and dual-role), there
- will be an additional module named dwc2.ko.

- non-periodic transfers, but of course the debug logs will be
- incomplete. Note that this also disables some debug messages
- for which the transfer type cannot be deduced.
