   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.

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