Hi,
ZBT-5926 is similar to ZBT-1226, it is using MediaTek MT7628AN, and ThinkWill ML7820+ as LTE chip,
I have flashed it with openwrt 18.06.5
everything works fine, only LTE does not work, there are no cdc-wdm0 or ttyUSB in /dev !
root@OpenWrt:~# ls /dev/
bus kmsg mtd2ro mtd6ro network_latency shm ttyS14 ttyS8
console log mtd3 mtdblock0 network_throughput tty ttyS15 ttyS9
cpu_dma_latency memory_bandwidth mtd3ro mtdblock1 null ttyS0 ttyS2 urandom
full mtd0 mtd4 mtdblock2 port ttyS1 ttyS3 watchdog
gpiochip0 mtd0ro mtd4ro mtdblock3 ppp ttyS10 ttyS4 watchdog0
gpiochip1 mtd1 mtd5 mtdblock4 ptmx ttyS11 ttyS5 zero
gpiochip2 mtd1ro mtd5ro mtdblock5 pts ttyS12 ttyS6
hwrng mtd2 mtd6 mtdblock6 random ttyS13 ttyS7
here is my usb devices:

the ZXIC Mobile Boardband is correct device, bcuz vendor firmware shows that too,
is there anyway to have /dev/cdc-wdm0 or /dev/ttyUSB ?
