3. Shouldn't "Linux Foundation 3.0 root hub" be "Linux Foundation 3.1 Gen 1
root hub"?

No, we don't say that from within the kernel.

But there's no reason we couldn't.  Greg, you could allocate a new
Product ID value for USB-3.1 root hubs and update lsusb to recognize
it.  (I don't know if it's worth including the "Gen 1" vs "Gen 2" part,
though.)

2. Please note that USB 3.0, USB 3.1 Gen1, and USB 3.2 Gen1 are in 
fact the same specification and feature the same exact performance 
capabilities. The USB Implementers Forum (USB-IF) recently rebranded 
USB 3.1 Gen1 to USB 3.2 Gen1. For more information about the change, 
please visit the USB-IF website at www.usb.org <https://www.usb.org/>.

That is one of the most confusing things I've read.
