The usb package
This library enables you to communicate with USB devices from userspace. It is implemented as a high-level wrapper around http://hackage.haskell.org/package/bindings-libusb bindings-libusb which is a low-level binding to the C library: http://libusb.org/ libusb-1.*.
The USB transfer functions in this library have a simple synchronous interface (they block) but are implemented using the libusb asynchronous interface. They integrate with the GHC event manager making them efficient (no busy-loops) and interruptible (throwing an exception to the thread executing a transfer immediately cancels the transfer).
If the GHC event manager is not available (because you're either not using GHC or because you're on Windows) the library degrades gracefully to the libusb synchronous implementation.
This documentation assumes knowledge of how to operate USB devices from a software standpoint (descriptors, configurations, interfaces, endpoints, control/bulk/interrupt/isochronous transfers, etc). Full information can be found in the http://www.usb.org/developers/docs/ USB 2.0 specification.
For an example how to use this library see the https://github.com/basvandijk/usb-example usb-example package or the http://hackage.haskell.org/package/ls-usb ls-usb package.
Also see the http://hackage.haskell.org/package/usb-safe usb-safe package which wraps this package and provides some strong safety guarantees for working with USB devices.
Finally have a look at the http://hackage.haskell.org/package/usb-iteratee usb-iteratee package which provides iteratee enumerators for enumerating bulk, interrupt and isochronous endpoints:
