Well done! However one could say that the problem is in modem_run.
The problem is that modem_run sets altsetting 1 on interface 1 then
exits. pppoax expects to see that altsetting. But when modem_run
exits it releases interface 1 which returns interface 1 to altsetting 0
(thanks to a change by Alan Stern (IIRC)). Then pppoax is run.
It needs altsetting 1 to work. I think the right solution is for pppoax
to set altsetting 1 on interface 1 itself. Just remove the test
if (alternate_ep != -1) {
in pppoa3.c, line 680 (untested).
Alan, what do you think? Is choosing altsetting 0 in usb_driver_release_interface
appropriate given that there are user space drivers around?
Ciao,
