I've been tinkering with developing a USB touchscreen gadget device on
a board using a Mentor USB peripheral controller (driver musb-hdrc).
The gadget I'm developing runs in userspace via gadgetfs. From what
I've been able to tell, there's no way to run multiple gadget devices
simultaneously using
So IMHO there are two cases
1. The configuration is fixed in the hardware - in which case we should
automatically set it in kernel, or from device tree.
2. The configuration is soft - in which case you need an ioctl you can
use on the port to change it - irrespective of whether sysfs also handles
Sorry for the long delay, Johan.

A recent optimization was made so that a request put on the
pending_list wouldn't get mapped for DMA until just before
preparing a TRB for it. However, this poses a problem in case
the request is dequeued or the endpoint is disabled before the
mapping is done as that would lead to dwc3_gadget_giveb
