libusb @1.0.22: build fails on 10.7.5: error: use of undeclared identifier 'kUSBDeviceSpeedSuper'

[kencu (Ken)]

'kUSBDeviceSpeedSuper' is supposed to be available on 10.7+ <​https://developer.apple.com/documentation/iokit/1425357-usbdevicespeed/kusbdevicespeedsuper> but apparently actually is not:

os/darwin_usb.c:1043:10: error: use of undeclared identifier 'kUSBDeviceSpeedSuper'; did you mean 'kUSBDeviceSpeedFull'?
    case kUSBDeviceSpeedSuper: dev->speed = LIBUSB_SPEED_SUPER; break;

simple patch allows it to build.

I already reported the problem to the developers: ​https://github.com/libusb/libusb/issues/410

The correct patch is to change #if MAC_OS_X_VERSION_MAX_ALLOWED >= 1070 to #if MAC_OS_X_VERSION_MAX_ALLOWED >= 1080.

shall we patch this in the repo, then? It'll be a while before a new version of libuv rolls out with this fixed.

[ryandesign (Ryan Carsten Schmidt)]

Yes.
