[Bug 1136228] Re: PCCard UMTS modem Option GT 3G+ is not recogniced by modem-manager
# udevadm info -a -n /dev/noz2
Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

And it's not an USB device, it's a PCCard. It hangs on the PCI bus.

[Bug 1136228] Re: PCCard UMTS modem Option GT 3G+ is not recogniced by modem-manager
Ah, so these are the weird nozomi-based option devices. What's the usb VID/PID of the device? Currently MM only handles the Nozomi device with VID 0x1931 and PID 0x000c. What's weird here is that we completely fail to load VID/PID, so only the generic plugin probes the port, and even this one will fail as VID/PID wasn't loaded. Also, please run: udevadm info -a -n /dev/noz2 And lsusb -v for this device. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1136228 Title: PCCard UMTS modem Option GT 3G+ is not recogniced by modem-manager To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/modemmanager/+bug/1136228/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
