pusb_set_configuration() triggers hotplug. All previous interfaces
are removed and all new interfaces are added. In our example, it
makes 6 calls to usb.agent (tested on 2.6.5).
Both in 2.4 and 2.6 kernels, there is an initial call to
pusb_set_interface() to set the default interface before calling
hotplug. So, all call to pusb_set_interface() are useless since
there is only one interface.

#if 0
if (pusb_set_configuration(fdusb, 1) < 0) {
report(0, REPORT_ERROR, "pusb_set_configuration 1");
return(-1);
}
#endif
I believe that comment is true even with
s/calling hotplug/calling the udsl_usb_probe() routine/
