Huawei E3372 HiLink dongle does not work with OpenWRT ver 19.07

I have Huawei E3372 HiLink dongle connected to USB port in OpenWRT based router. It worked properly with OpenWRT ver 17 but after upgrade to ver 19.07 - not.
This dongle has SD card slot for additional memory.
According to OpenWRT forum, I add in /etc/usb-mode.json such entry:

Code:"12d1:14dc": {
"*": {
"t_vendor": 4817,
"t_product": [ 5340 ],
"mode": "HuaweiNew",
"msg": [ ]
}
},12d1 (hex) = 4817 (dec) and 14dc (hex) = 5340 (dec).

All usb modeswitch tools are installed and configured in the same way as in ver 17 of OpenWRT.
Dongle is propery recognized by kernel as You can see:

Code:root@Bioama-1:/# cd sys/devices/platform/ehci-platform/usb1/1-1
root@Bioama-1:/sys/devices/platform/ehci-platform/usb1/1-1# cat idVendor
12d1
root@Bioama-1:/sys/devices/platform/ehci-platform/usb1/1-1# cat idProduct
14dc
root@Bioama-1:/sys/devices/platform/ehci-platform/usb1/1-1# cat product
HUAWEI_MOBILEBut after reboot both modem and SD card is not available, not listed in /dev dir.

What else can I do to get it working? What to check? Any Idea?
