Hey I am looking for the Linux User Guide, how to handle the EC200S.
I added the kernel support so lsusb show the correct device.
Bus 002 Device 004: ID 2c7c:6002 Quectel Wireless Solutions Co., Ltd.
I can bring it to CDC Ethernet mode via this AT Command: AT+QCFG=“usbnet”,1
[ 1698.836297] usb 2-1.2: new high-speed USB device number 4 using ehci-platform
[ 1699.009140] cdc_ether 2-1.2:1.0 usb1: register ‘cdc_ether’ at usb-5800d000.usbh-ehci-1.2, CDC Ethernet Device, ae:0c:29:a3:9b:6d
[ 1699.386288] usbcore: registered new interface driver option
[ 1699.390610] usbserial: USB Serial support registered for GSM modem (1-port)
[ 1699.401621] option 2-1.2:1.2: GSM modem (1-port) converter detected

[ 1699.463305] usb 2-1.2: GSM modem (1-port) converter now attached to ttyUSB1
Or with this AT Command: AT+QCFG=“usbnet”,3
To a rndis device
[ 6517.031151] usb 2-1.2: USB disconnect, device number 5
[ 6520.906282] usb 2-1.2: new high-speed USB device number 6 using ehci-platform
[ 6521.076251] rndis_host 2-1.2:1.0 usb1: register ‘rndis_host’ at usb-5800d000.usbh-ehci-1.2, RNDIS device, 7a:4c:b8:c5:5f:a0

[ 6521.118530] usb 2-1.2: GSM modem (1-port) converter now attached to ttyUSB1
WIth busybox udhcpc -i usb1 I can setup a IP Address for USB1
6: usb1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UNKNOWN group default qlen 1000
link/ether 8a:fd:f5:0f:2d:fa brd ff:ff:ff:ff:ff:ff
inet 192.168.43.100/24 brd 192.168.43.255 scope global usb1
valid_lft forever preferred_lft forever
inet6 fe80::88fd:f5ff:fe0f:2dfa/64 scope link
valid_lft forever preferred_lft forever
But I can not reach the mobile internet via this device.
If it test the internet connection via an AT Command like
AT+QPING=1,“www.google.de”
it works.
