MyUSB 1.3.0, which was released two days ago, is now fully documented in the site wiki. As per the usual procedure with each MyUSB library version release, I’ve created a migration page in the Wiki to aid in the migration of projects based on old library versions to the latest version.
I’ve since discovered a flaw in the USB to Serial converter demonstration sample project, which prevents the correct drivers from being installed. A fix will be uploaded in the next few days, but it can be manually fixed via the following change.
In MyUSB/Demos/USBtoSerial/Descriptors.c, change the value of the class attribute of DeviceDescriptor (first structure in the file) from the value 0x00 to 0x02. This declares the device correctly as being a CDC class device, and allows Windows to use its own drivers for it (once helped along by the INF file located in the USBtoSerial directory).
