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
