* usb: zero copy work, multiple endpoints with single context, async ioJosh Blum2010-09-261-356/+118
| | | | | | | | | Heavy work on the zero copy interface and endpoint wrappers to properly use the async io. The global libusb session starts a thread to run the event handler, the async callbacks push completed transfers onto a thread-safe bounded buffer. The managed buffer creation routines use the bounded buffer to efficiently pop off completed transfers. works on linux, throws a weird exception on cleanup
* usb: work on libusb code to use a single context across all callsJosh Blum2010-09-251-54/+29
| | | | | | | | libusb allocation stuff had been moved inside of smart pointer classes to handle automatic cleanup the public device handle implementation now holds an actual libusb device inside of it needs testing - all platforms

* usrp1: Handle degenerate managed send buffer casesThomas Tsou2010-08-271-4/+19
| | | | | | | | Handle degenerate usage of send buffer commits. If the buffer is destroyed without ever being submitted, submit a zero byte transfer to return control to the underlying structure. If a committed buffer is re-committed, then report an error message and return 0 bytes back.
