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. |

for which the transfer type cannot be deduced. |
