I encountered a problem with package usb-switchmode on OpenWRT 18.06 on my WR1043NDv1.
I am trying to use my Huawei E5577C-321 Mifi router with TP_link WR1043ND v1.8 router using USB port.
After instaling from official repository by opkg package usb-switchmod (file /sbin/usbmode) on run I get error:
Error loading shared library libjson-c.so.4: No such file or directory (needed by /sbin/usbmode)
Mifi router is not recognized correctly as network interface.
I downgraded to LEDE 17.05.7 and problem with usb-switchmode does not occur.
I retested with with my Raspberry Pi Zero using Openwrt 18.06.1 and problem witch usb-switchmode also does not occur.
I think this is problem with mips_24kc package (usb-switchmode).
I tried this yersterday around 20:00 (GMT+2) but since there were problems with repo I used mirror from Poland for 18.06.2 and mirror from Netherlands for 18.06.1.
If packet usb-switchmode on mirrors was not reliable (?) I can retry today evening using primary repo.
There was a problem with builds during the last day or two that had the wrong things in the wrong place for just about everything. It has since been resolved.
