Hi all,

I'm new to usb_modeswitch and am having some issues.

TL;DR:
It worked the first time after soft reboot, but I am now unable to switch modes.

I'm trying to connect a raspberry pi through a Huawei E1552/E1800/E173 (AT&T USBConnect Force 4G). I installed usb_modeswitch, and ran lsusb which showed:

Code: Select all

Bus 001 Device 004: ID 12d1:1446 Huawei Technologies Co., Ltd. E1552/E1800/E173 (HSPA modem)

I then soft rebooted, and got:

Code: Select all

Bus 001 Device 006: ID 12d1:1506 Huawei Technologies Co., Ltd. E398 LTE/UMTS/GSM

which allowed me to connect to the internet fine using wvdial.

I then edited /etc/usbmode_switch.conf with the following (retrieved from `tar -xzvf /usr/share/usb_modeswitch/configPack.tar.gz 12d1\:1446`):

Code: Select all

DisableSwitching=0
EnableLogging=1

# AT&T Modem

DefaultVendor=0x12d1
DefaultProduct=0x1446

TargetVendor=0x12d1
TargetProduct=0x1506

Since then, I haven't been unable to put the modem into the correct mode.

My logs (/var/log/usb_modeswitch_1-1.2\:1.0) are as follows:

Strange that Driver is none...

I then edited /etc/usbmode_switch.conf with the following:

Don't use the global config file for device configuration data!
It will be ignored.

Furthermore, the configuration is O.K., you don't need to edit anything. You'd rather want to find out why the mode switching works during a reboot but not directly when plugging. (I hope I understood that correctly.)

There are at least two possible sources for trouble: insufficient power on the USB port or a problem/conflict with the storage driver, probably timing-related.

Try again without tampering with any files, with logging enabled. But before plugging the modem, run this:

Code: Select all

# modprobe usbstorage
# echo 5 >/sys/module/usb_storage/parameters/delay_use

Hi Josh,

Thanks for getting back to me.

I first ran:

sudo reboot

, the output of lsusb was

Anyway. To get back to your requests, when I run:

Code: Select all

pi@raspberrypi ~ $ sudo modprobe usbstorage
FATAL: Module usbstorage not found.

Unfortunately my raspberry pi reboots when you plug something new in over USB (power surge), so I'll need to grab a powered hub before I can test the results from hot-plugging. After rebooting I get the same result.

WRT not editing the global config - how should I best get it to autostart in modem mode?

Strangely, if I use a USB hub (to stop the Pi rebooting), hotplugging the device automatically modswitches correctly (if the Pi is on) - the problem is only noticed when cold booting the pi.

I did try increasing the usb_storage delay to 5 seconds, but it doesn't seem to help.

I thought that unbinding and binding the USB device might work, but I get access denied when trying to write to '/sys/bus/usb/drivers/usbhid/unbind' or 'bind', even when sudo.

[reinosk8]

i have added a script "autostart" in the /etc/init.d route with permisions 755
the script contains the following lines:

#
sudo service udev stop
sleep 2
sudo service udev start
sleep 9
#

sudo service udev restart doesn't work properly

to activate de script u might run:
sudo update-rc.d autostart defaults

dirty solution but u can clean it with a good script (case $1, start) stop), etc)

sorry about my english, i only speak spanish
