ISO packet size is up to 1023 for full speed device.
Upon completion of ISO reception, reported length of incoming packet
was truncated to one byte only.
This results in incorrect data stream for higher bit rates
48 samples * 4 bytes per sample * 2 channels = 384 bytes of data
and 128 was reported.
There is no change in logic extending xact_len to uint16_t fixes the issue.
Some compilers don't support the GNU extension `typeof` so their definitions
of `hw_set_alias` can't inherit their type from their argument, and the best
we can do is have `hw_set_alias` act the same as `hw_set_alias_untyped`.
This requires an explicit cast when the macro is used instead, otherwise
IAR generates error Pe132 'expression must have pointer-to-struct-or-union
type but it has type "void *"'.
The same goes for `hw_clear_alias`.
strings.h is not an ISO header file, so IAR generates fatal error Pe1696
'cannot open source file "strings.h"'. Even though strncasecmp isn't an
ISO C library function, IAR's runtime library defines it, though it
declares it in string.h instead.
Field started (regardind transfer) was only cleaed when transfer
was finished.
For audio devices set interface is called many times.
When there is no audio (silence) set interface requests zero
lenght bandwithd that in turn calls dcd_edpt_close().
When endpoint is closed due to set interface request transfer
should not longer be started since it will block next start transfer
with assert.
This just sets 'started' to false when endpoint is closed.
Removing the Hardcoded interface numbers from the video descriptors allow the user to add other interfaces before or after the Video Control Interface and Video Streaming Interface
dfu_moded_open() only works correct when its called on DFU interface
descriptor. It means that DFU is the only one interface in configuration
or driver is called after all others interface drivers were tried and
gave up.
If other interface is supported and but driver for DFU is called first
(this is the case for BTH and RNDIS).
Code after while loop (that was not entered) has an TU_ASSERT that will
make set_configuration to fail.
Now TU_VERIFY is called first to make sure open code is called for DFU
only and not other interface descriptors like in other drivers.
