set correct endpoint type for isochronous transfers
Pointed out by Felix Domke
Daniel Drake [Fri, 11 Apr 2008 20:40:07 +0000 (21:40 +0100)]
Linux: fire multiple URBs at once for split transfers
This results in a significant performance increase for bulk transfers
larger than 16kb, and fixes a bug where data would be spliced and mixed
between two simultaneously submitted transfers to the same endpoint.
It also allows isochronous transfers larger than 16kb to be submitted.
This commit also improves cancellation - the library now understands
what is going on.

Constify some return data

Daniel Drake [Tue, 25 Mar 2008 16:24:30 +0000 (16:24 +0000)]
Isochronous endpoint I/O
Due to variable-sized structures, this involved changing allocation
mechanism. All transfers must now be allocated and freed through
libusb.
A synchronous function is missing, and I could do with writing a few
more helper functions to simplify things.

Separate transfer allocation and submission
Leads to some hefty API changes. Now we're much more similar to the
Linux kernel model.
Problems with dealing with asynchronous control transfers are passed
on to the user, basically you must allocate a buffer, start with the
setup, and put the data after. This won't make much sense until
documented (soon...)

Rework URB API naming
Now refer to everything as "transfers" as consistent with the USB spec
libusb_transfer is now a kind of transfer handle. To reduce confusion
with libusb_bulk_transfer and libusb_control_transfer, those have been
renamed to libusb_{control,bulk}_transfer_request.

Persistent libusb_device storage
Devices are now assigned a session ID (currently busnum:devaddr) which
is used to distinguish unique devices.
Now multiple callers of libusb_get_device_list will get the same
libusb_device structure instances.

Add convenience function to find and open a device by USB VID+PID
Lots of libusb apps I write are simple test apps not intended to be real
apps. Having a function available to quickly locate my device will be
handy in such situations.
Daniel Drake [Thu, 6 Mar 2008 23:25:20 +0000 (23:25 +0000)]
Rework device discovery API
libusb_find_devices and libusb_get_devices are no more
libusb_get_device_list obtains a list of libusb_device structures for all
known devices in the system.
Each libusb_device now has a reference count, defaulting to 1 on
instantiation. The reference count of 1 refers to the fact that it is
present in the list in this scenario.
Opening a device adds a pointer to the libusb_device structure in the
handle, so that also adds a reference. Closing the device removes that
reference.
The function to free the device list can optionally unref all the devices
inside.
In future we will make the libusb_device instances all "global" so that if
the app calls get_device_list twice it actually gets the same libusb_device
structure references back. This way we can start to track disconnects, and
we can investigate adding a unique "session ID" to each libusb_device, an
identifier guaranteed to be unique to that device until reboot.
