[PATCH] Darwin big endian issue

[mk]

Hello,

submit_control_transfer() in libusb/os/darwin_usb.c is causing some trouble running avrdude on my G4 PowerPC running OS X 10.5.8:

$ LIBUSB_DEBUG=3 avrdude  -p t2313 
[...]
libusb:info [darwin_open] device open for access
libusb:info [darwin_async_io_callback] an async io operation has completed
libusb:info [op_handle_events] checking fd 3 with revents = 10000
libusb:info [op_handle_events] checking fd 5 with revents = 10001
libusb:info [darwin_control_callback] handling control completion with status -536854447
libusb:error [darwin_control_callback] control error = transaction timed out
libusb:warning [libusb_control_transfer] unrecognised status code 1
avrdude: Warning: cannot query manufacturer for device: Result too large
[...]

setup->wValue, setup->wIndex and setup->wLength are, as the source comment says, already in bus order, but DeviceRequestAsyncTO expects host order, according to Apple's documentation: ​http://developer.apple.com/mac/library/DOCUMENTATION/Darwin/Reference/IOKit/USB_h/index.html#//apple_ref/c/tdef/IOUSBDevRequestTO

With the attached patch avrdude is working nicely
