Hello,
I tried to setup a SMS server with a HUAWEI E160 using smstools3.
Receiving Test-SMS works as expected for some hours.
But after a while the E160 did not receive SMS anymore.
When looking into the smstools3 log everything looks normal.

I found that after unplugging the USB dongle an plugging again the missing SMS are received imediatly.
So I guess that there is a problem with USB.
My first thougt was: bad power supply. So I replaced it. But no luck.
And in fact the WAN port (network chip) of my NanoPi R2S ist connected via USB too. But there are no drop outs on WAN ....
Looking at dmesg did not help at all. The ringbuffer seems quite small. Same with logread.
How to find the problem?
