Hello, I just uploaded a new release of Maurício C. Antunes' bindings-libusb to hackage. See: http://hackage.haskell.org/package/bindings-libusb-1.4.2 bindings-libusb is a bindings-DSL based, low-level binding to libusb. This release adds support for the recent libusb-1.0.5. BTW, there is work being done to create a Windows port for libusb. This means that in the near future libusb and therefor bindings-libusb and my usb packages will work on all major platforms, hooray! regards, Bas
