### Installing usb_modeswitch on a camera with fpv, lite and NVR hi3536[ed]v100 firmware
|
|
|
|
We check with the e3372h modem.
|
|
|
|
Camera:
|
|
```
|
|
curl -o /usr/sbin/usb_modeswitch http://fpv.openipc.net/files/usb-modeswitch/musl/usb_modeswitch && chmod +x /usr/sbin/usb_modeswitch
|
|
curl -o /usr/lib/libusb-1.0.so.0.3.0 http://fpv.openipc.net/files/usb-modeswitch/musl/libusb-1.0.so.0.3.0 && chmod +x /usr /lib/libusb-1.0.so.0.3.0
|
|
ln -s -f /usr/lib/libusb-1.0.so.0.3.0 /usr/lib/libusb-1.0.so
|
|
ln -s -f /usr/lib/libusb-1.0.so.0.3.0 /usr/lib/libusb-1.0.so.0
|
|
```
|
|
NVR:
|
|
```
|
|
ntpd-Nnq
|
|
curl -k -L -o /usr/sbin/usb_modeswitch https://github.com/OpenIPC/sandbox-fpv/raw/master/usb-modeswitch/musl/usb_modeswitch && chmod +x /usr/sbin/usb_modeswitch
|
|
curl -k -L -o /usr/lib/libusb-1.0.so.0.3.0 https://github.com/OpenIPC/sandbox-fpv/raw/master/usb-modeswitch/musl/libusb-1.0.so .0.3.0 && chmod +x /usr/lib/libusb-1.0.so.0.3.0
|
|
ln -s -f /usr/lib/libusb-1.0.so.0.3.0 /usr/lib/libusb-1.0.so
|
|
ln -s -f /usr/lib/libusb-1.0.so.0.3.0 /usr/lib/libusb-1.0.so.0
|
|
ln -s -f /lib/libc-2.32.so /lib/libc.so
|
|
```

|
|
ln -s -f /lib/libc-2.32.so /lib/libc.so
|
|
```
|
|
</details>
|
|
|
|
|
|
|
|
We enter this text for e3372h into the file `/etc/network/interfaces.d/eth1` (we will create the file if it does not exist):
|
|
```
|
|
auto eth1
|
|
iface eth1 inet dhcp
|
|
pre-up sleep 4
|
|
pre-up if [ ! -z "`lsusb | grep 12d1:1f01`" ]; then usb_modeswitch -v 0x12d1 -p 0x1f01 -J; fi
|
|
pre-up if [ ! -z "`lsusb | grep 12d1:14dc`" ]; then modprobe usbserial vendor=0x12d1 product=0x14dc; fi
|
|
pre-up modprobe rndis_host
|
|
pre-up sleep 2
|
|
```
|
|
|
|
We jerk the modem, try `ifup eth1` or reboot. If the network has risen (there is eth1 in `ip a`), in interfaces we can replace manual with auto.
|
|
|
|
#### Problems
|
|
If usb_modeswitch switched the modem to cdc_ethernet, then when rebooting the system, for example, via reboot, the interface does not come up - error ip: SIOCGIFFLAGS: No such device. Therefore, if you need to completely reboot the system for the modem to work, you need to disconnect the power supply to the modem before rebooting.
|
|
|
|
### Result
|
|
The e3372h modem with hilink firmware should be displayed as the eth1 network interface and, with a working SIM card inserted, distribute the Internet to the camera:
|
|
```
|
|
Trying to send message 1 to endpoint 0x01 ...
|
|
OK, message successfully sent
|
|
Read the response to message 1 (CSW) ...
|
|
Device seems to have vanished after reading. Good.
|
|
Device is gone, skip any further commands
|
|
-> Run lsusb to note any changes. Bye!
