gobi_loader
2+
3+
gobi_loader is a firmware loader for Qualcomm Gobi USB chipsets. These devices
4+
appear in an uninitialised state when power is applied and require firmware
5+
to be loaded before they can be used as modems. gobi_loader adds a udev rule
6+
that will trigger loading of the firmware and make the modem usable.
7+
8+
Installing:
9+
10+
make; make install
11+
12+
You also need the qcserial driver. This is included in kernels 2.6.30 and
13+
later. Ensure that it has the IDs for your device. If not, add a line like
14+
15+
{USB_DEVICE(0x1234, 0x5678)},
16+
17+
to the id_table structure in drivers/usb/serial/qcserial.c and
18+
rebuilt. This device is the firmware loading device and is not usable
19+
as a modem. When loaded, qcserial should create a /dev/ttyUSB
20+
device. Check that /etc/udev/rules.d/60-gobi.rules has an entry for your device
21+
- if not, copy one of the existing lines and change the vendor and product IDs.
22+
Note that a device line is only needed for the firmware loading ID, not the
23+
modem ID.
24+
25+
Now you need the modem firmware. This can be obtained from a Windows
26+
install - alternatively it may be possible to download from your
27+
vendor's site and extracted with wine. You need the amss.mbn and
28+
apps.mbn files corresponding to your mobile provider. For Gobi 2000
29+
devices you also need UQCN.mbn. As yet, I don't have a good mapping
30+
between devices and the appropriate firmware, so you'll need to figure
31+
this out yourself. Remember that some mobile providers use CDMA and
32+
some use GSM - the CDMA firmware will typically be a smaller file than
33+
the GSM firmware (approximately 5MB for CDMA firmware, approximately
34+
9MB for GSM firmware). On my install, these files could be found in a
35+
QDLService/Packages directory.
36+
37+
Please don't ask me for firmware. It's copyright Qualcomm and I can't
38+
redistribute it.
39+
40+
Copy the appropriate firmware into /lib/firmware/gobi. Unload and
41+
reload the qcserial driver or reboot your machine. Assuming you
42+
installed the application and rules correctly, and assuming that
43+
qcserial and the rules file both contain your modem devices, your
44+
firmware will now load. The firmware loading device will now detach
45+
from your system and reattach with a different ID. If you had to add
46+
the firmware loading device to qcserial.c then you will probably also
47+
need to add the modem device. However, the modem device does not need
48+
to be added to the udev rules file.
49+
50+
A /dev/ttyUSB device will now exist for your modem. Recent versions of
51+
network-manager should automatically pick it up - older versions (and
52+
any other modem management software) may need more assistence.
