What I am wondering about is if how it is done in usbnet is suitable for
such a high speed device (LTE), possibly very chatty on USB. I am suspecting
that it polls for incoming USB packets too infrequently (only through a
"tasklet_schedule", not continuously). Do you think that could be a case? If
so, maybe the usbnet needs a flag for "continuous" polling (not sure if it
is possible with USB bulk ports?) or write that part independently of the
usbnet code.
I recognized that when the errors are coming, during high load (like loading a
web page with a lot of images etc.), I get status -EOVERFLOW on the urb. Does
this mean that the driver is not keeping up on reading the data?
From Documentationusb/error-codes.txt:
-EOVERFLOW (*) The amount of data returned by the endpoint was
greater than either the max packet size of the
endpoint or the remaining buffer size. "Babble".
