following endpoint decoders:

To assign a decoding group to a Request RPipe:
Step 1 Click the Apply Decoding Scripts button on the Toolbar.
OR
Right-click the Control Transfer field to display the USB Device Request menu.
Step 2 Select Map RPipe to Class/Vendor Decoding to display the Request Recipient
and Endpoints dialog box.
Step 3 Click the Request RPipes tab to display the Request RPipes dialog box:
The Recipient field shows all Class and Vendor Request recipients found in the
trace file. The RPipe field shows all Class and Vendor Request RPipes found in
the trace file. The displays shows the Otg Host, HWA address, and Type (Class
or Vendor) for the recipient. On the right are the names of Class/Vendor
Decoding groups currently assigned to recipients. If blank, no decoding is
assigned for a recipient.
Step 4 Select a recipient.
Step 5 Display the Class/Vendor Decoding Groups drop-down menu. The
Class/Vendor Decoding Groups are the same as for Request Recipients.
Step 6 Select a decoding group.
