Ping?
Can anybody at least point me at a decent resource on how to build udev
rules?
Thanks,
Justin

Hi all,
I am trying to get my Huawei E220 3G modem working with the new Linux
kernels.
The USB device registers 3 functions. 2 usb-serial devices, and 1
usb-storage device. Unfortunately, a firmware bug is causing the
device to reset when userland apps try to mount the usb-storage device.
A simple way to get things working is to just kill udevd after the
serial ports are registered, and before the scsi device scan
completes, but obviously this is not ideal ;-) .
I have been experimenting by creating /etc/udev/rules.d/01-blacklist,
and adding rules to try ignore the storage device.
This:
SUBSYSTEMS=="usb", ATTRS{idVendor}=="12d1", OPTIONS:="ignore_device"
successfully ignores the USB device entirely (serial and storage
options).
This:
SUBSYSTEMS=="usb", ATTRS{idVendor}=="12d1",
ATTRS{bInterfaceClass}=="08", OPTIONS:="ignore_device"
should only match the storage device, and ignore it, but it doesn't
seem to work.
I have tried more exotic solutions like:
SUBSYSTEM=="usb-serial", ATTRS{idVendor}=="12d1",
GOTO="blacklist_skip_huawei"
SUBSYSTEMS=="usb", ATTRS{idVendor}=="12d1", OPTIONS:="ignore_device"
LABEL="blacklist_skip_huawei"
but the storage device is still mounted.
Is there any way to debug the rule parsing to see exactly which rules
are matched/violated?
Can anybody perhaps help with tips/advice on how to construct this
blacklist?
Thanks,
Justin
