An EPICS module for support of SIS 3150 and 3153 USB to VME interface boards .
The support is a driver derived from asynPortDriver. The driver allows records to perform VME I/O using standard asyn device support.
The driver is based on a library from SIS for the low-level USB to VME transactions. This library is included in this module, so nothing else needs to be downloaded.

Thanks to Mark Rivers for the implementation.
