1b4014cb28 Set the pointer type, to make the compiler happy, otherwise it might 
complain about the incompatible pointer types.

d4d7011a44 Don't assume libusb headers are always in libusb-1.0. 
Use pkg-config to add correct include paths for libusb regardless of the
platform.

4a64c18350 move newUSBTransfer as a vanilla function to transfer.go.

a47809fda8 Simplify the C part even more - the buffer that xfer uses for 
transferring data is the same as the one that was created in
newUSBTransfer.

83a4778988 wait() does not need the buffer passed explicitly, it's already stored 
in t.buf.

1860441a7b iso.go is no longer needed, the only iso-specific part lives in

31b3ac1c67 move iso.c to transfer.c, as it's used for all transfers. 
move transfer callback to transfer.go.

d7ed6d67e6 Rename iso_callback to transfer_callback, it's used for all transfer 
types.

87abb704d7 Make all transfer types use a generic endpoint.transfer() function 
that uses libusb's asynchronous interface.

c9c2757fe6 Replace the libusb_bulk_transfer with the same prepare-submit-wait 
routine iso transfers use.

80b2741a2c Rename Transfer to usbTransfer, it's internal to gousb. 
Move usbTransfer and it's methods to transfer.go, it's not only used by
iso transfers.

66a1f45cd9 Remove the artificial limit. The worst case is a longer timeout for the 
transfer is required.

c27a77b547 Pass the max buffer size down to the alloc_transfer. Use the number 
of iso packets matching the buffer size. This guarantees that the
transfer size is smaller or equal to the buffer.
Device will transfer less data if iso transfer response does not utilize the
maximum available number of iso packets per microframe or doesn't fill
the packets entirely.

a35725f4fb When extracting transfer data, pay attention to the size of the buffer 
provided by the user, which may be smaller than the length of data
received in the transfer.

a19ac0f654 Per http://www.beyondlogic.org/usbnutshell/usb5.shtml#EndpointDescriptors: 
bits 0-3 are endpoint number, 4-6 reserved, set to zero, bit 7 is
direction. Bits 0-3 is 0x0f.

4d60ebb065 Move usb_test to a separate package, in line with opensource Go 
expectations. Multiple packages per directory are not supported in this
realm ;) And with a separate package, the dot import seems unnecessary.

f13728c6e1 Set the MaxIsoPacket field in the endpoint info if the endpoint is 
an isochronous endpoint. Use MaxIsoPacket as the iso packet size
when preparing the iso transfer.

4319ef2cc2 Revert "Use the calculated max iso packet size." 
The libusb_get_max_iso_packet_size ignores the endpoint information and
will return the same size for all endpoints, even if the current
alternative configuration does not support given size.

This reverts commit a6e284610b.

f0ae807096 Fix race condition with C.libusb_handle_events that might still being called while libusb_exit is executed. Use C.libusb_handle_events_timeout_completed which accepts timeouts and pass 100 ms timeout. This is the recommended way to deal with this issue, see http://libusb.sourceforge.net/api-1.0/group__poll.html#ga43e52b912a760b41a0cf8a4a472fbd5b and http://libusb.sourceforge.net/api-1.0/group__poll.html#ga4989086e3f0327f3886a4c474ec7c327 2013-08-14 00:34:00 -07:00
