Login to RQM with admin privileges. Goto Admin > System Properties > Lab Resources Properties. You can add new Type here.
Next goto Admin > System Properties > Test Plan Environment Types select the type you want to add and then click on set type.

I just downloaded and installed RQM 2.0 Express.

How can I add an environment type of "Device" to a test plan in RQM 2.0?

By default only the environment types of "Application Server", "Browsers", "CPU", "Database", OS, "ManagementAgent", and "TestAdapater" are available.

Sure, no problem. The mentioned defect is on interim builds post 2.0 GA. The GA version should work just fine.

Thanks.
