I want the columns to line up so that they look sane and someone can
understand what they mean :)

Not sure what you mean. This is a simple copy-paste from the spec document.
Do you want me to put quotation marks around the multi-word Data column?

Still does not look correct to me, how about you?

[Patch v3] usb: hcd.h: Fix the values of SetHubDepth and GetPortErrorCount to match USB 3.1 specification

2015-08-07 Thread Tal Shorer
>From the usb 3.1 spec available at http://www.usb.org/developers/docs/
table 10-7 (Hub Class Requests) specifies the values for SetHubDepth and
GetPortErrorCount as:

Request bmRequestType bRequest wValue wIndex wLength Data
SetHubDepth 0010B SET_HUB_DEPTH Hub Depth Zero Zero None
GetPortErrorCount 10100011B GET_PORT_ERR_COUNT Zero Port Two Number of Link 
Errors on this port

Fix these two values to match the spec.
