After random time USB Bus died completely..

The same problem is on 4.14 kernel also.

Here is log from at91 kernel 4.19

Because of message "Forbidden. Data submitted too often. Please wait a few minutes. Contains contacts. ",
And can't upload its to this post because of "reached maximum" error,
I have loaded listings to dropmefiles.

list1.txt

I tried compile kernel from kernel.org, but error the same:

Code: Select all

list2.txt

As you can see, I connecting GSM modem to linux by USB.
I've trying connect SIM5300 as CDC-ACM device,
trying to connect SIM5300 as GSM modem (1-port) converter only,
trying to connect SIM7600 as GSM modem (1-port) converter only,
trying to connect SIM7600 as NDIS and GSM modem (1-port) converter,

Try monitoring the voltage and current delivered to your system.
If you don't have the meters, then at least decouple the USB power load by using a USB hub (with an external power supply) for all of your USB devices.
