Good afternoon, I am seeing a message in my syslog that instructs me to "Tell Linux-usb@xxxxxxxxxxxxxxx to add your device to a proper driver.". This is me delivering the message as instructed. I have just plugged in a Quectel EC25-E LTE Module, mounted on a Micro-PCIe to USB adaptor board. Broadly speaking this is very similar to the Quectel UC20 module, that I think is already supported. The full section of the syslog is as follows: > Jun 6 10:14:53 thorne-ul-dt kernel: [ 2662.332593] usbcore: > registered new interface driver usbserial > Jun 6 10:14:53 thorne-ul-dt kernel: [ 2662.332615] usbcore: > registered new interface driver usbserial_generic > Jun 6 10:14:53 thorne-ul-dt kernel: [ 2662.332631] usbserial: USB > Serial support registered for generic > Jun 6 10:14:53 thorne-ul-dt kernel: [ 2662.332646] usbserial_generic > 3-2.4.1:1.0: The "generic" usb-serial driver is only for testing and > one-off prototypes. > Jun 6 10:14:53 thorne-ul-dt kernel: [ 2662.332648] usbserial_generic > 3-2.4.1:1.0: Tell linux-usb@xxxxxxxxxxxxxxx to add your device to a > proper driver. > Jun 6 10:14:53 thorne-ul-dt kernel: [ 2662.332649] usbserial_generic > 3-2.4.1:1.0: generic converter detected > Jun 6 10:14:53 thorne-ul-dt kernel: [ 2662.332732] usb 3-2.4.1: > generic converter now attached to ttyUSB0 > Jun 6 10:14:53 thorne-ul-dt kernel: [ 2662.332744] usbserial_generic > 3-2.4.1:1.1: The "generic" usb-serial driver is only for testing and > one-off prototypes. > Jun 6 10:14:53 thorne-ul-dt kernel: [ 2662.332746] usbserial_generic > 3-2.4.1:1.1: Tell linux-usb@xxxxxxxxxxxxxxx to add your device to a > proper driver. > Jun 6 10:14:53 thorne-ul-dt kernel: [ 2662.332747] usbserial_generic > 3-2.4.1:1.1: generic converter detected > Jun 6 10:14:53 thorne-ul-dt kernel: [ 2662.332805] usb 3-2.4.1: > generic converter now attached to ttyUSB1 > Jun 6 10:14:53 thorne-ul-dt kernel: [ 2662.332815] usbserial_generic > 3-2.4.1:1.2: The "generic" usb-serial driver is only for testing and > one-off prototypes. > Jun 6 10:14:53 thorne-ul-dt kernel: [ 2662.332817] usbserial_generic > 3-2.4.1:1.2: Tell linux-usb@xxxxxxxxxxxxxxx to add your device to a > proper driver. > Jun 6 10:14:53 thorne-ul-dt kernel: [ 2662.332818] usbserial_generic > 3-2.4.1:1.2: generic converter detected > Jun 6 10:14:53 thorne-ul-dt kernel: [ 2662.332884] usb 3-2.4.1: > generic converter now attached to ttyUSB2 > Jun 6 10:14:53 thorne-ul-dt kernel: [ 2662.332892] usbserial_generic > 3-2.4.1:1.3: The "generic" usb-serial driver is only for testing and > one-off prototypes. > Jun 6 10:14:53 thorne-ul-dt kernel: [ 2662.332893] usbserial_generic > 3-2.4.1:1.3: Tell linux-usb@xxxxxxxxxxxxxxx to add your device to a > proper driver. > Jun 6 10:14:53 thorne-ul-dt kernel: [ 2662.332895] usbserial_generic > 3-2.4.1:1.3: generic converter deteccted > Jun 6 10:14:53 thorne-ul-dt kernel: [ 2662.332950] usb 3-2.4.1: > generic converter now attached to ttyUSB3 > Jun 6 10:14:53 thorne-ul-dt kernel: [ 2662.332958] usbserial_generic > 3-2.4.1:1.4: The "generic" usb-serial driver is only for testing and > one-off prototypes. > Jun 6 10:14:53 thorne-ul-dt kernel: [ 2662.332960] usbserial_generic > 3-2.4.1:1.4: Tell linux-usb@xxxxxxxxxxxxxxx to add your device to a > proper driver. > Jun 6 10:14:53 thorne-ul-dt kernel: [ 2662.332961] usbserial_generic > 3-2.4.1:1.4: generic converter detected > Jun 6 10:14:53 thorne-ul-dt kernel: [ 2662.333017] usb 3-2.4.1: > generic converter now attached to ttyUSB4 > Jun 6 10:14:53 thorne-ul-dt ModemManager[1110]: <warn> (ttyUSB0): > port attributes not fully set > Jun 6 10:14:53 thorne-ul-dt ModemManager[1110]: <warn> (ttyUSB4): > port attributes not fully set > Jun 6 10:14:53 thorne-ul-dt ModemManager[1110]: <warn> (ttyUSB2): > port attributes not fully set > Jun 6 10:14:53 thorne-ul-dt ModemManager[1110]: <warn> (ttyUSB3): > port attributes not fully set > Jun 6 10:14:53 thorne-ul-dt ModemManager[1110]: <warn> (ttyUSB1): > port attributes not fully set Previously I thought I had got the driver to come up after creating a modified options module that added details of the modules vendor and device IDs, then run `modprobe option vendor=0x2c7c product=0x0125`. However this now seems to fail, possibly because I do not have the modified kernel and module installed right now. Error from that step is as follows: > Jun 6 10:14:53 thorne-ul-dt kernel: [ 2662.387374] option: unknown > parameter 'vendor' ignored > Jun 6 10:14:53 thorne-ul-dt kernel: [ 2662.387376] option: unknown > parameter 'product' ignored > Jun 6 10:14:53 thorne-ul-dt kernel: [ 2662.387474] usbcore: > registered new interface driver option > Jun 6 10:14:53 thorne-ul-dt kernel: [ 2662.387495] usbserial: USB > Serial support registered for GSM modem (1-port) > Jun 6 10:14:55 thorne-ul-dt ModemManager[1110]: <warn> (ttyUSB2): > port attributes not fully set > Jun 6 10:14:55 thorne-ul-dt ModemManager[1110]: <warn> (ttyUSB3): > port attributes not fully set > Jun 6 10:15:01 thorne-ul-dt CRON[29989]: (munin) CMD (if [ -x > /usr/bin/munin-cron ]; then /usr/bin/munin-cron; fi) > Jun 6 10:15:01 thorne-ul-dt CRON[29991]: (root) CMD (if [ -x > /etc/munin/plugins/apt_all ]; then /etc/munin/plugins/apt_all update > 7200 12 >/dev/null; elif [ -x /etc/munin/plugins/apt ]; then > /etc/munin/plugins/apt update 7200 12 >/dev/null; fi) > Jun 6 10:15:04 thorne-ul-dt systemd[1]: Started CUPS Scheduler. > Jun 6 10:15:04 thorne-ul-dt colord[1172]: (colord:1172): Cd-WARNING > **: failed to get session [pid 30202]: No such device or address > Jun 6 10:15:04 thorne-ul-dt colord[1172]: message repeated 3 times: [ > (colord:1172): Cd-WARNING **: failed to get session [pid 30202]: No > such device or address] > Jun 6 10:15:33 thorne-ul-dt ModemManager[1110]: <warn> (ttyUSB4): > close blocked by driver for more than 7 seconds! > Jun 6 10:15:33 thorne-ul-dt ModemManager[1110]: <warn> (tty/ttyUSB0) > failed to parse QCDM version info command result: -7 > Jun 6 10:16:09 thorne-ul-dt ModemManager[1110]: <warn> (ttyUSB4): > close blocked by driver for more than 7 seconds! > Jun 6 10:16:09 thorne-ul-dt ModemManager[1110]: <info> Creating > modem with plugin 'Generic' and '5' ports > Jun 6 10:16:09 thorne-ul-dt ModemManager[1110]: <warn> Could not > grab port (tty/ttyUSB1): 'Cannot add port 'tty/ttyUSB1', unhandled > serial type' > Jun 6 10:16:09 thorne-ul-dt ModemManager[1110]: <warn> Could not > grab port (tty/ttyUSB4): 'Cannot add port 'tty/ttyUSB4', unhandled > serial type' > Jun 6 10:16:09 thorne-ul-dt ModemManager[1110]: <warn> (ttyUSB2): > port attributes not fully set > Jun 6 10:16:09 thorne-ul-dt ModemManager[1110]: <info> Modem for > device at > '/sys/devices/pci0000:00/0000:00:14.0/usb3/3-2/3-2.4/3-2.4.1' > successfully created > Jun 6 10:16:09 thorne-ul-dt ModemManager[1110]: <info> Modem: state > changed (unknown -> disabled) > Jun 6 10:16:09 thorne-ul-dt NetworkManager[1124]: <info> > [1496740569.8654] manager: (ttyUSB2): new Broadband device > (/org/freedesktop/NetworkManager/Devices/6) > Jun 6 10:16:09 thorne-ul-dt NetworkManager[1124]: <info> > [1496740569.8656] device (ttyUSB2): state change: unmanaged -> > unavailable (reason 'managed') [10 20 2] > Jun 6 10:16:09 thorne-ul-dt NetworkManager[1124]: <info> > [1496740569.8657] device (ttyUSB2): modem state 'enabling' > Jun 6 10:16:09 thorne-ul-dt ModemManager[1110]: <info> Modem > /org/freedesktop/ModemManager1/Modem/0: state changed (disabled -> > enabling) > Jun 6 10:16:09 thorne-ul-dt ModemManager[1110]: <warn> (ttyUSB2): > port attributes not fully set > Jun 6 10:16:09 thorne-ul-dt ModemManager[1110]: <warn> (ttyUSB3): > port attributes not fully set > Jun 6 10:16:10 thorne-ul-dt ModemManager[1110]: <info> Modem > /org/freedesktop/ModemManager1/Modem/0: 3GPP Registration state > changed (unknown -> registering) > Jun 6 10:16:10 thorne-ul-dt ModemManager[1110]: <info> Modem > /org/freedesktop/ModemManager1/Modem/0: 3GPP Registration state > changed (registering -> home) > Jun 6 10:16:10 thorne-ul-dt ModemManager[1110]: <info> Modem > /org/freedesktop/ModemManager1/Modem/0: state changed (enabling -> > registered) > Jun 6 10:16:10 thorne-ul-dt NetworkManager[1124]: <info> > [1496740570.4375] device (ttyUSB2): state change: unavailable -> > disconnected (reason 'modem-available') [20 30 58] > I had successfully added support for the module to a Yocto build, the diff for which can be found at https://github.com/Quectel-Community/meta-quectel-community/blob/master/recipes-kernel/linux/linux-yocto/0001-Add-Quectel-EC25-USB-Serial-Driver-Support.patch It probably needs some work before being ready for adding to the Linux Kernel but it might form a helpful reference point. Currently I am running an Ubuntu 16.04 distribution with the kernel details being: $ uname -a Linux thorne-ul-dt 4.4.0-72-generic #93-Ubuntu SMP Fri Mar 31 14:07:41 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux If there are any further details I can provide that may be of use, please get in touch and I will do what I can to be of help.
