Is there any detailed documentation on the FreeBSD usb device driver
api?
This chapter helped me a lot to understand how this all works:
http://www.freebsd.org/doc/en_US.ISO8859-1/books/arch-handbook/usb.html
I sort of have it working by hacking ubsa.c to look for the sierra
vendor id and product id of 0xfff in
the usb_match function and return match. Then in the usb_attach code I
look again for the vendor and
product id of 0xfff and then send the control message to put it in modem
mode.
if ( uaa->vendor == USB_VENDOR_SIERRA && uaa->product == 0xfff )
It maybe a good idea to add 0xFFF to the usbdevs.
Does the "umass" driver attach to the 0xFFF device? I would recommend
adding this as a quirk to umass.c then.
Actually I am not sure. The device when in TRU-Install mode looks like umass
device,
it has a place to insert a microSD card, and also cdrom drive that when mounted
has
the software to install on windows. When it is put in modem mode the cdrom
disappears
but the umass device is still there. One other thing is that when installed on
a linux
system there are 3 serial ports. The first port is used for the modem, one is
used for a
builtin gps receiver and I think the 3rd passes signal strength information to
the windows
software.
There are patches attached (ubsa.c_patch, umass_c.patch, usbdevs.patch)
I am using to kill the "zeroconf" CD on the UMTS. They do not always
work - i.e. umass_attach does not wait until the device is really
detached. But setting USB_DEBUG helps :-)
{
ubsa_request_real( sc, 0x0b, 1, 0x40 );
ucom->sc_dying = 1;
goto error;
}
This puts in modem mode with product id of 0x0023 which i have plugged
into usbdevs and also put in ubsa.c
so now I get a ucom device and can successfully run ppp. The problem I
am running into now is sometime after
it remove the device I will get a page fault panic in the kernel.
What kind of panic is this?
I think it is related to the sending the
control_message - something is not cleaned up when I "goto error" in the
USB_ATTACH function.

Yeah this looks like the panic I am getting. One of my fellow workers needed the
usb device - so I am waiting for us to get another to continue testing.
There are two patches, one to ohci_pci.c, the other to usb_subr.c. One
of them is not correct - after kldunloading the module you may run into
problems. But it makes everyday life easier - at least you can remove
the card and re-insert.
And finally, you will need something to increase your ubsa buffers, I am
using the ubsa.c_buffers_patch attached. (Crude, but cleaner than
http://www.freebsd.org/cgi/query-pr.cgi?pr=119227)
For the time being I just hard coded larger buffers - like I see you did below.
Thanks for your input. When I get my replacement modem I'll let you know
how I make out.

I am attaching an lsusb listing from a linux system FYI.
