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

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