I did some further investigation with wireshark - in attachment two
captures - from windows (modem is working) and from openbsd (not
working).
I also found some differences in behavior of the device attachment and
processing. According to RNDIS specs[1]:
1) MinorVersion of REMOTE_NDIS_INITIALIZE_MSG must be set to 0x00000000
(paragraph 2.2.2), but in our code it's set to 1:
sys/dev/usb/if_urndis.c:
459 msg->rm_ver_minor = htole32(1);
2) The REMOTE_NDIS_INITIALIZE_MSG message must come first, but in
OpenBSD first message is getting hardware address (same file):
1462 if (urndis_ctrl_query(sc, OID_802_3_PERMANENT_ADDRESS, NULL, 0,
1463 &buf, &bufsz) != RNDIS_STATUS_SUCCESS) {
1464 printf(": unable to get hardware address\n");
1465 splx(s);
1466 return;
1467 }
In yota-windows.pcapng the REMOTE_NDIS_INITIALIZE_MSG is in frame 27.
In yota-openbsd.pcapng OID_802_3_PERMANENT_ADDRESS is in fram 290.
Maybe someone with USB protocol understanding can take a look at the
captures and note the problems in device responses?
I also tried latest snapshot, the problem still persist.
