Just learning the USB API.
Can someone point me to a driver to use as an example of a synchronous
call? Do
I need to use a mutex?
I have a device that that does the equivalent of control transfers over
an interrupt pipe.
So I need to send data, get status, send more data, get status again,
and then finally start
retrieving data; all using interrupt transfers. Been going over the
drivers in the kernel
and they are all looking to be doing async or synchronous back through
user mode.
