They use RNDIS, so the host sees them as network interfaces (the driver is rndis_host). lsusb: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ bDeviceClass 2 Communications idVendor 0x1076 GCT Semiconductor, Inc. idProduct 0x8002 iManufacturer 1 GCT SEMICONDUCTOR Inc iProduct 2 Modem Yota bInterfaceClass 224 Wireless bInterfaceSubClass 1 Radio Frequency bInterfaceProtocol 3 RNDIS ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ dmesg: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ [37908.902059] usb 2-1: new high-speed USB device number 5 using ehci_hcd [37909.016784] usb 2-1: New USB device found, idVendor=1076, idProduct=8001 [37909.016790] usb 2-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [37909.016795] usb 2-1: Product: Modem Yota [37909.016799] usb 2-1: Manufacturer: GCT SEMICONDUCTOR Inc [37909.017941] scsi7 : usb-storage 2-1:1.0 [37910.020806] scsi 7:0:0:0: CD-ROM GDM Mass PQ: 0 ANSI: 0 CCS [37910.040402] sr1: scsi3-mmc drive: 0x/0x caddy [37910.040821] sr 7:0:0:0: Attached scsi CD-ROM sr1 [37911.023887] usb 2-1: USB disconnect, device number 5 [37911.780107] usb 2-1: new high-speed USB device number 6 using ehci_hcd [37911.894782] usb 2-1: New USB device found, idVendor=1076, idProduct=8002 [37911.894788] usb 2-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [37911.894792] usb 2-1: Product: Modem Yota [37911.894796] usb 2-1: Manufacturer: GCT SEMICONDUCTOR Inc [37911.895640] rndis_host 2-1:1.0: dev can't take 1558 byte packets (max 1458), adjusting MTU to 1400 [37911.896799] rndis_host 2-1:1.0: eth1: register 'rndis_host' at usb-0000:00:1d.7-1, RNDIS device, 00:09:3b:f0:1a:40 [37911.910891] systemd-udevd[14153]: renamed network interface eth1 to yota [37922.034017] yota: no IPv6 routers present ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The device seems to contain a DHCP-server that always provides the same settings: 10.0.0.10/24 gw/dns 10.0.0.1. The server is rather buggy so I've sticked to static IP configuration in NM. You can't really configure it — it just works. Through the web interface you can check connection status, update firmware (they say, you won't need this, because it will be updated automatically), and switch the device on/off (the relevant code is commented out in HTML for some reason, though it does work). Web GUI gets status from http://10.0.0.1/status. I bet, their software for Windows and Mac gets data the same way.The data looks like this: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ InterfaceType=lte 3GPP.IMSI=<not really interesting> 3GPP.UICC-ID=<not really interesting> 3GPP.IMEI=<not really interesting> 3GPP.IMEISV=<not really interesting> DeviceName=Modem Yota RfVersion=no information AsicVersion=GDM7240R1 FirmwareVersion=3.7 State=Connected UpdateState=NotStarted UpdateProgress=0 ConnectedTime=894 3GPP.SINR=4 3GPP.RSSI=-86 3GPP.MCC=250 3GPP.MNC=11 3GPP.PLMN=25011 3GPP.RoamingStatus=0 3GPP.CGI=25011BF2A900 3GPP.CI=BF2A900 3GPP.eNBID=BF2A9 3GPP.HNBN= 3GPP.CSGT= 3GPP.CenterFreq=2642500 3GPP.TxPWR=23.0 3GPP.SPN=Yota SessionID=3420730 3GPP.IsIdle=0 IP=10.138.173.239 SubnetMask=255.255.255.0 DefaultGateway=10.0.0.1 DHCP=10.0.0.1 DNS=10.0.0.1 SentBytes=97808 ReceivedBytes=253845 MaxDownlinkThroughput=99232 MaxUplinkThroughput=88064 CurDownlinkThroughput=53480 CurUplinkThroughput=13048 TotalHandoversCount=0 SucceededHandoversCount=0 NewFirmwareVersion= 3GPP.RSRP=-116 3GPP.RSRQ=-11.0 MSISDN= SupportsConnectDisabling=0 CQI=8 DownlinkMCSMain=3,9,6 DownlinkMCSDiv=3,6,4 UplinkMCS=3,4,2 NBRi=earfcn,ci,rsrp ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -- Кирилл Елагин _______________________________________________ networkmanager-list mailing list networkmanager-list@gnome.org https://mail.gnome.org/mailman/listinfo/networkmanager-list
