Instead of *always* dumping raw ctrl bytes, let's decode standard requests which will make the lives of those debugging DWC3 quite a bit easier. Output will now look like so: irq/34-dwc3-1594 [000] d..1 107.573081: dwc3_ctrl_req: Get Device Descriptor(Index = 0, Length = 18) irq/34-dwc3-1594 [000] d..1 107.573694: dwc3_ctrl_req: Set Address(Addr = 01) irq/34-dwc3-1594 [000] d..1 107.588319: dwc3_ctrl_req: Get Device Descriptor(Index = 0, Length = 18) irq/34-dwc3-1594 [000] d..1 107.588816: dwc3_ctrl_req: Get Configuration Descriptor(Index = 0, Length = 9) irq/34-dwc3-1594 [000] d..1 107.589191: dwc3_ctrl_req: Set Configuration(Config = 3) irq/34-dwc3-1594 [000] d..1 107.589846: dwc3_ctrl_req: Get BOS Descriptor(Index = 0, Length = 5) irq/34-dwc3-1594 [000] d..1 107.590146: dwc3_ctrl_req: Get BOS Descriptor(Index = 0, Length = 22) irq/34-dwc3-1594 [000] d..1 107.590546: dwc3_ctrl_req: Get Configuration Descriptor(Index = 0, Length = 9) irq/34-dwc3-1594 [000] d..1 107.590840: dwc3_ctrl_req: Get Configuration Descriptor(Index = 0, Length = 69) irq/34-dwc3-1594 [000] d..1 107.591138: dwc3_ctrl_req: Get Configuration Descriptor(Index = 1, Length = 9) irq/34-dwc3-1594 [000] d..1 107.591541: dwc3_ctrl_req: Get Configuration Descriptor(Index = 1, Length = 32) irq/34-dwc3-1594 [000] d..1 107.591834: dwc3_ctrl_req: Get Device Descriptor(Index = 0, Length = 18) irq/34-dwc3-1594 [000] d..1 114.701005: dwc3_ctrl_req: Get Device Descriptor(Index = 0, Length = 18) irq/34-dwc3-1594 [000] d..1 114.721080: dwc3_ctrl_req: Get Device Descriptor(Index = 0, Length = 18) irq/34-dwc3-1594 [000] d..1 114.722709: dwc3_ctrl_req: Get Device Descriptor(Index = 0, Length = 18) irq/34-dwc3-1594 [000] d..1 114.728979: dwc3_ctrl_req: Get Device Descriptor(Index = 0, Length = 18) irq/34-dwc3-1594 [000] d..1 114.730544: dwc3_ctrl_req: Get Device Qualifier Descriptor(Index = 0, Length = 10) irq/34-dwc3-1594 [000] d..1 115.776018: dwc3_ctrl_req: Get Configuration Descriptor(Index = 0, Length = 9) irq/34-dwc3-1594 [000] d..1 115.776760: dwc3_ctrl_req: Set Configuration(Config = 0) irq/34-dwc3-1594 [000] d..1 115.777676: dwc3_ctrl_req: Get Configuration(Length = 1) irq/34-dwc3-1594 [000] d..1 115.924797: dwc3_ctrl_req: Get Device Descriptor(Index = 0, Length = 18) irq/34-dwc3-1594 [000] d..1 115.929025: dwc3_ctrl_req: Get String Descriptor(Index = 0, Length = 500) irq/34-dwc3-1594 [000] d..1 115.929566: dwc3_ctrl_req: Get String Descriptor(Index = 1, Length = 500) irq/34-dwc3-1594 [000] d..1 115.930911: dwc3_ctrl_req: Get String Descriptor(Index = 0, Length = 500) irq/34-dwc3-1594 [000] d..1 115.931528: dwc3_ctrl_req: Get String Descriptor(Index = 2, Length = 500) irq/34-dwc3-1594 [000] d..1 115.932950: dwc3_ctrl_req: Get String Descriptor(Index = 0, Length = 500) irq/34-dwc3-1594 [000] d..1 115.933533: dwc3_ctrl_req: Get String Descriptor(Index = 3, Length = 500) Note that Class and Vendor requests won't be decoded for obvious reasons. Those will be printed as a raw sequence of bytes. This patch has been tested against a normal host (both Linux and Windows) and USB30CV Chapter 9 tests.

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
