8	  For host mode, if you choose to build the driver as dynamically
9	  linked modules, the core module will be called dwc2.ko, the PCI
10	  bus interface module (if you have a PCI bus system) will be
11	  called dwc2_pci.ko, and the platform interface module (for
12	  controllers directly connected to the CPU) will be called
13	  dwc2_platform.ko. For all modes(host, gadget and dual-role), there
14	  will be an additional module named dwc2.ko.

97	  for which the transfer type cannot be deduced.
