GroupName

The GroupName entry defines the name for the group of requests described in the

file. This name also appears in the SETUP field's request decoding context menu.

For example,

GroupName=Imaging Class

shows up in the context menu this way:

GroupType

The GroupType entry defines the type of requests in the file. There are three (3)

possible settings for the GroupType entry: GroupType=Standard,

GroupType=Class, and GroupType=Vendor.

GroupType=Standard

A set GroupType=Standard requests defines the standard USB requests. Note

that in the case of defining standard USB requests, there can be only one .req file.

CATC supplies the standard request definitions in the file standard.req.

GroupType=Class

GroupType=Class indicates that the file defines a set of class-specific USB

requests. This group type also requires a ClassCode entry, which specifies the

USB-assigned device class code. For example,

GroupType=Class

ClassCode=0x03
