Package: usb-modeswitch-data
Version: 20150115-1
Severity: normal
Dear Maintainer,
This bug is very similar to archived bug # 751271. After upgrading from Debian
7 to Debian 8, my Huawei modem will no longer switch from "usb storage" to
"modem mode" when the device is plugged in.
I am experiencing this problem in latest Debian 8.2, udev 215, usb_modeswitch
2.2.0+repack0-2, and usb-modeswitch-data 20150115-1. I am using the Huawei
12d1:1446 device -- the same mentioned in archived bug # 751271.
The catch-all udev rule does not work:
# Generic entry for all Huawei devices
ATTRS{idVendor}=="12d1", ATTR{bInterfaceNumber}=="00",
ATTR{bInterfaceClass}=="08", RUN+="usb_modeswitch '%b/%k'"
The switching does not occur by udev automatically. Switching by manually
calling usb_modeswitch works fine:
usb_modeswitch -v 12d1 -p 1446 -J
And... a few moments later by new device 12d1:1506 appears and all is well.
If I simply modify the udev rule, everything works automatically. For example,
this rule works:
ATTR{idVendor}=="12d1", ATTR{idProduct}=="1446", RUN+="/lib/udev/usb_modeswitch
'%b/%k'"
This does not work, however:
ATTR{idVendor}=="12d1", ATTR{idProduct}=="1446", ATTR{bInterfaceNumber}=="00",
RUN+="/lib/udev/usb_modeswitch '%b/%k'"
Here's an except from `udevadm info` **before switching**:

unload module index
Unloaded link configuration context.
I should also note that running /lib/udev/usb_modeswitch '2-1/2-1:1.0' manually
does not cause the USB device to switch.
Interestingly, running /lib/udev/usb_modeswitch '2-1' does cause the USB device
to switch.
This could be why setting the rule on the USB device works but setting the rule
on the USB device **interface** does not.
I'd be happy to provide more information as needed.
Thanks!
