I am using functionfs to transfer data with a bulk highspeed endpoint.
However I am only able to achieve Data rates of 8Mb/s.
What ways are there to improve the speed?

I have added module parameters to the functionfs module in the kernel
commandline.
I used escaped quotes surrounding the Strings that have space.
This is my commandline:

The struct driver_info ax88178_info is assigned the function

High-speed USB connections revert back to full-speed signalling when
the device goes into suspend. This takes several milliseconds, and
during that time it's not possible to tell reliably whether the device
has been disconnected.
On some platforms, the Wake-On-Disconnect circuitry gets confused

In preparation of combining the dwc2/s3c-hsotg driver in a single DRD driver,
the defines in dwc2/hw.h needs to get updated so that the s3c-hsotg driver can

Similar to the DWC3 dual-role driver config, the default mode for the
dwc2/s3c-hsotg driver is a dual-role driver.
When the driver is built as a module the dwc2.ko and dwc2_platform.ko are
