- add support for the hislip protocol over TCPIP PR #331
- allow to list TCPIP resources PR #326
In order to discover resources over all subnets psutil needs to be installed
- attempt to stabilize access to USBTMC resources PR #335
Reduce the number of device reset performed and only set all settings if it
is meaningful (more than one settings exist.)
