Serial via USBHost on GHI .NETMF 4.2?

The USB Host tutorial here (GHI Electronics – Where Hardware Meets Software) references GHIElectronics.NETMF.USBHost and USBHostController, which I can’t find in the latest version of the SDK. I’m just getting my feet wet, so I may be looking in the wrong place.

The Gadgeteer.Modules.GHIElectronics.UsbHost class I have only supports specific events (Mouse, KB, USBDrive), which doesn’t help when I want to do serial IO.

Any help?

I found the answer. GHIElectronics.NETMF.USBHost has become GHI.Premium.USBHost.

Also, USBH_Device has moved from GHIElectronics.NETMF.USBHost to GHI.Premium.System.

(Can I mark my own post as an answer to my question? For anyone who comes across this later?)
