To avoid having to claim/release interfaces all the time, and having to
trigger interface changes from several places, all interfaces are now
claimed ahead of time.
This commit also makes us avoid changing the active interface when it's
not necessary.
Changing the active interface has side effects such as resetting the
active alternate setting -- which is extremely undesirable because it
would require the emulated software to change the alternate setting
again, which isn't supposed to be necessary at all.
This fixes Your Shape, which submits isochronous transfers on an
endpoint that only exists in alt setting 6 right after submitting
control transfers (which would have reset to alt setting 0 prior to
this fix).
Even though libusb is supposed to be thread-safe, in practice
it's not (at least on Windows); getting a list of devices from two
different threads can result in libusb crashes. This is easily
fixed by waiting for the scan thread to complete scanning instead
of running the scan on the CPU thread.
This also fixes an issue that I had overlooked in the initial
implementation: IOS interfaces such as OH0 are sometimes opened
every frame, in which case we were doing a full device scan every
single frame on the CPU thread!
Fixes an embarrassing bug that made the implementation utterly useless.
This fixes Your Shape hanging on shutdown. The game was waiting for an
interrupt transfer to be cancelled, and Dolphin wasn't cancelling
transfers on the correct endpoint.
The total buffer size for isochronous transfers should be a u32,
not a u16. It is easy to hit the bug with devices such as cameras,
which require larger buffers.
This fixes Your Shape.
This also fixes the length type for bulk and interrupt transfers,
which should be u32 as that's what IOS supports. I'm not sure why
I made them u16... probably because OH0 uses u16 for most lengths...
* Use font based sizing for row height. Fits more rows on screen.
* Adds whitespace for better formatting and minimum column width.
Helps prevent frequent resizing while scrolling.
WindowModal allows alt+tabing to the render window, but prohibits interaction
with parent windows (controller settings window and the main dolphin window).
The system menu is passing the SHA1 hash of the save data to ES
to sign, not the save data itself.
Fixes save import in the System Menu for saves that were exported
by Dolphin.
