Huawei E220 modem not recognised after upgrade

I use a Huawei E220 modem, which has been working well until a recent upgrade. However, it is not recognised as a modem anymore. Looking into daemons.log I see:

Nov 21 10:07:01 localhost udevd[234]: unknown key 'SYSFS{idProduct}' in /etc/udev/rules.d/50-huawei-e220.rules:1
Nov 21 10:07:01 localhost udevd[234]: invalid rule '/etc/udev/rules.d/50-huawei-e220.rules:1'

Nov 21 10:07:01 localhost udevd[234]: invalid rule '/etc/udev/rules.d/50-huawei-e220.rules:1'
Nov 21 10:07:01 localhost udevd[234]: unknown key 'SYSFS{idProduct}' in /etc/udev/rules.d/50-huawei-e220.rules:2
Nov 21 10:07:01 localhost udevd[234]: invalid rule '/etc/udev/rules.d/50-huawei-e220.rules:2'
Nov 21 10:07:01 localhost udevd[234]: unknown key 'SYSFS{idProduct}' in /etc/udev/rules.d/50-huawei-e220.rules:3
Nov 21 10:07:01 localhost udevd[234]: invalid rule '/etc/udev/rules.d/50-huawei-e220.rules:3'

The .rules file looks like:

SUBSYSTEM=="usb", SYSFS{idProduct}=="1003", SYSFS{idVendor}=="12d1", RUN+="/usr/local/bin/huawei-e220"
SUBSYSTEM=="usb", SYSFS{idProduct}=="1003", SYSFS{idVendor}=="12d1", RUN+="/bin/sleep 5"
SUBSYSTEM=="usb", SYSFS{idProduct}=="1003", SYSFS{idVendor}=="12d1", RUN+="/sbin/modprobe usbserial vendor=0x12d1 product=0x1003"

Google or the forum search didnt help. Any tips are appreciated. Thanks!

Re: Huawei E220 modem not recognised after upgrade

Maybe you don't have the right packages installed.
(SYSFS= is not any more recognized by Udev.)

From which package belong this files?
Please send the result of:
pacman -Qo /etc/udev/rules.d/50-huawei-e220

Do you have usb_modeswitch installed?
Check with:
pacman -Q usb_modeswitch

Re: Huawei E220 modem not recognised after upgrade

yes i have usb_modeswitch

pacman -Qo /etc/udev/rules.d/50-huawei-e220
does not return any result. if i remember correctly, there was some package i got from AUR, which prepared all necessary configurations, however i dont remember now which one.

anyways, my setup worked just fine up until the recent update

Re: Huawei E220 modem not recognised after upgrade

Are you using NetworkManager?
And modemmanager?
If you are using "networkmanager", "modemmanager" and "usb_modeswitch-1.2.0-1", remove the file (/etc/udev/rules.d/50-huawei-e220) and it must work.
If it still does not work, then you could edit /etc/usb_modeswitch.conf , and change EnableLogging=1.
This way you could have a lot of debug information in /var/log/usb_modeswitch_<device> (when you plug the Huawei E220) to help fix the issue.

Re: Huawei E220 modem not recognised after upgrade

Just create a group called "usb' . Add your user to this group with gpasswd -a 'user' 'group' without the ' as root.

As root go to /lib/udev/rules.d/50-default and change libusb to group = usb

You will have to do it every time there is an upgrade (of whether linux or udev) I don't remember. Had this issue with a ZTE 3G modem.

Hope it helps.

Re: Huawei E220 modem not recognised after upgrade

Many thanks for the tips!

@mcsilva

I removed the /etc/udev/rules.d/50-huawei-e220.rules file. I checked that all other packages are installed. However my device is still not recognised as a modem. (If I remember correctly, the initial reason for creating the .rules file was because was was not recognised with the default setup, and at the time this change made it work). Will try to debug it over the weekend as you suggested.

@arunvragh

You mean I should edit /lib/udev/rules.d/50-udev-default.rules ? In this file I see:

# 'libusb' device nodes
SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", MODE="0664"
SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", IMPORT{builtin}="usb_id"

Can you please tell me exactly how to add it to the usb group? (What is the exact syntax?)

Re: Huawei E220 modem not recognised after upgrade

Yes.

as root groupadd usb
then gpasswd -a 'user' usb without the '

Then edit the file replace MODE with GROUP and 0664 with usb
Restart and you should be on your way.

Re: Huawei E220 modem not recognised after upgrade

Sorry for the delay in answering this (I have been mostly away).

I tried your advices:

* removed /etc/udev/rules.d/50-huawei-e220.rules
* added the usb group to /lib/udev/rules.d/50-udev-default.rules as instructed

However my problem is only partially solved. When the computer boots with the usb modem connected it is never recognised as a modem. Then I remove it and plug it in several times. Eventually (after 5-10 times) it is recognised as a modem. This process is slow and painful and quite far from the "plug and play" behaviour that I enjoyed before. The output I see in /var/log/usb_modeswitch* is (it looks exactly the same whether the device is or is not recognised as a modem):

Any more help in debugging this issue is appreciated. Thanks!

Re: Huawei E220 modem not recognised after upgrade

What's in /usr/local/bin/huawei-e220 (included in your old rule)?

I have a Huawei e1552 myself and just need usb_modeswitch installed plus an udev rule file.

Here's the rule with your modem's product ID in place so you can test it:

#
# /etc/udev/rules.d/50-huawei-e220
#
# udev-rule for switching modems from storage to modem
SUBSYSTEM=="usb", RUN+="/lib/udev/usb_modeswitch --vendor 0x12d1 --product 0x1003 --type option-zerocd"

Re: Huawei E220 modem not recognised after upgrade

Sorry. You need to install usb_modeswitch from community. and i hope you have a wvdial.conf installed. give user permissions to /usr/bin/wvdial. Then just open a terminal and type wvdial. If there are errors you may have to tinker with wvdial.conf. By the way have you installed the drivers that came with the Huawei modem from your ISP?
