Hello,
I had the following configuration on FC23 (systemd-222-14.fc23) which
worked perfectly (ARM system):
cat /etc/udev/rules.d/8-usb-modem.rules
# Huawei E169
SUBSYSTEM=="tty", ATTRS{idVendor}=="12d1", ATTRS{idProduct}=="1001",
ATTRS{product}=="HUAWEI Mobile", ATTRS{version}==" 1.10",
ENV{ID_USB_INTERFACE_NUM}=="00" SYMLINK+="ttyUSB-modem-at"
SUBSYSTEM=="tty", ATTRS{idVendor}=="12d1", ATTRS{idProduct}=="1001",
ATTRS{product}=="HUAWEI Mobile", ATTRS{version}==" 1.10",
ENV{ID_USB_INTERFACE_NUM}=="01" SYMLINK+="ttyUSB-modem-aux"
SUBSYSTEM=="tty", ATTRS{idVendor}=="12d1", ATTRS{idProduct}=="1001",
ATTRS{product}=="HUAWEI Mobile", ATTRS{version}==" 1.10",
ENV{ID_USB_INTERFACE_NUM}=="02" SYMLINK+="ttyUSB-modem-third"
After upgrade to FC24 (systemd-udev-229-8.fc24.armv7hl) I have the
problem that ttyUSB-modem-at link is not set.
lrwxrwxrwx 1 root root 7 Jul 1 18:49 ttyUSB-modem-aux -> ttyUSB2
lrwxrwxrwx 1 root root 7 Jul 1 18:49 ttyUSB-modem-third ->
ttyUSB3
I tried also:
# OK:
KERNEL=="ttyUSB1", SUBSYSTEM=="tty", ATTRS{idVendor}=="12d1",
ATTRS{idProduct}=="1001", ATTRS{product}=="HUAWEI Mobile",
ATTRS{version}==" 1.10" SYMLINK+="ttyUSB-modem-at"
# NOT OK:
KERNEL=="ttyUSB1", DRIVERS=="option", SUBSYSTEM=="tty",
ATTRS{idVendor}=="12d1", ATTRS{idProduct}=="1001",
ATTRS{product}=="HUAWEI Mobile", ATTRS{version}==" 1.10"
SYMLINK+="ttyUSB-modem-at"
So when something more specific correct filter is added it doesn't work
any more (I tried several different more distinct filters):
I tried already: udevadm info --attribute-walk /dev/ttyUSB1 which looks
good
First lines are:
looking at device
'/devices/platform/soc@01c00000/1c14000.usb/usb3/3-1/3-1.1/3-1.1:1.0/ttyUSB1/tty/ttyUSB1':
KERNEL=="ttyUSB1"
SUBSYSTEM=="tty"
DRIVER==""
looking at parent device
'/devices/platform/soc@01c00000/1c14000.usb/usb3/3-1/3-1.1/3-1.1:1.0/ttyUSB1':
KERNELS=="ttyUSB1"
SUBSYSTEMS=="usb-serial"
DRIVERS=="option1"
ATTRS{port_number}=="0"
looking at parent device
'/devices/platform/soc@01c00000/1c14000.usb/usb3/3-1/3-1.1/3-1.1:1.0':
KERNELS=="3-1.1:1.0"
SUBSYSTEMS=="usb"
DRIVERS=="option"
ATTRS{authorized}=="1"
ATTRS{bAlternateSetting}==" 0"
ATTRS{bInterfaceClass}=="ff"
ATTRS{bInterfaceNumber}=="00"
ATTRS{bInterfaceProtocol}=="ff"
ATTRS{bInterfaceSubClass}=="ff"
ATTRS{bNumEndpoints}=="03"
ATTRS{interface}=="Data Interface"
ATTRS{supports_autosuspend}=="1"
This one looks also good:
ls -l /dev/serial/by-id/usb-ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ_HUAWEI_Mobile-if00-port0
lrwxrwxrwx 1 root root 13 Jul 1 18:49
/dev/serial/by-id/usb-ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ_HUAWEI_Mobile-if00-port0 ->
../../ttyUSB1
I don't think I did anything wrong so it looks to be a bug.
Any ideas?
Thank you.
Ciao,
Gerhard
