How do I test my USB 3.0 speed?

Typically, newer PCs with USB 3.0 support have both USB 3.0 and USB 2.0 controllers, and both those ports are exposed. The receptacles on USB 3.0 ports are usually blue to distinguish from the receptacles on USB 2.0 ports, which are black. So, if the PC has a blue port, that is a good indication of USB 3.0 support.

What is USB SuperSpeed?

USB 3.0, also known as SuperSpeed USB, is the next major revision of the Universal Serial Bus (USB), a hardware interface that supports the exchange of data between a host computer and peripherals. Enhancements in the USB 3.0 specification were driven by the need for faster transfer rates and better power efficiency.

What are the different levels of USB driver testing?

The lowest level is the usb controller hardware; Host Controller Driver(HCD) and USB Device (or Peripheral) Controller(UDC) driver testing can share many of the same tools, if both use Linux. Those drivers need testing in many modes, since the higher levels each implement different protocols for accessing peripheral functionality.

Does Linux support OTG driver testing?

(On some hardware Linux supports OTG. OTG uses both host and gadget APIs, and adds mode negotiation support that needs testing.) Each of those has at least two layers of device drivers to test.

What tools do I need to debug a USB device?

If you’re bringing up new USB hardware with Linux, perhaps with embedded or at least non-PCI controllers, you may find it hard to debug without hardware tools such as a USB protocol sniffer or a logic analyser. There are probably a dozen or more other vendors; look around.
