      USB: GADGET: optionally force full-speed for net2280 UDC · 2f076077
      Alan Stern authored
      This patch (as1656) adds a module parameter to the net2280 UDC driver
      to force full-speed operation.  It is intended for testing purposes,
      where one wants to check how well a full-speed device performs when
      attached to a high-speed bus.  Without this parameter it would be
      necessary to interpose a full-speed hub; otherwise the net2280 would
      connect at high speed.

      USB: altsetting overrides for usbtest · d0b4652f
      Alan Stern authored
      The usbtest driver includes some rather simple-minded logic for
      selecting an altsetting to test.  It doesn't work well for the g_zero
      gadget, because it selects altsetting 0 (which doesn't have
      isochronous endpoints) rather than altsetting 1 (which does have them,
      if the gadget's hardware supports them).  This prevents usbtest's
      isochronous tests (15, 16, 22, and 23) from working with g_zero.
      
      Since g_zero is one of the most common gadget drivers used for USB
      testing, usbtest should do a better job of supporting it.  But since
      some programs may rely on the current scheme for selecting
      altsettings, I didn't want to change it.
      
      Instead, this patch (as1655) adds a module parameter to usbtest, which
      can be used to override the default altsetting.  Since usbtest is
      never used by normal users (most distributions probably don't even
      build it), the new module parameter won't inconvenience anybody.  In
      any case, it is entirely optional -- leaving it unset preserves the
      existing behavior.
      
      The patch also fixes a related bug in usbtest: After selecting an
      altsetting, the driver neglects to store its selection.
