I'm wondering how libusb @ windows is notified about pending data. Probably not using file descriptors but something else ... I'd suggest to use CONFIG_WIN32 instead of CONFIG_POLL, to make clear what this is about. You can #ifdef out the whole block with all three usb_host_*_fd functions, and the libusb call which registers these callbacks somewhere further down in the code. The later place should probably get a /* FIXME */ in the #else branch as I expect we need to do something on windows too. cheers, Gerd

This is a hack to support compilation with Mingw-w64 which provides a libusb-1.0 package, but no poll.h. Signed-off-by: Stefan Weil <sw@weilnetz.de> --- I did not test whether this USB host code works on Windows, but at least it compiles with this hack. Suggestions for a better fix are welcome.
