I was wondering if there were any Silicon Lab Modules SPI to USB that could work as both a USB Host and Peripheral? Optimally it would be cool for the device to generate an internal VBUS power so that no external regulator needed for supplying power to a peripheral when it's acting as a host.
As I am using a Blue Gecko module the goal is to have a silicon lab USB module that can be a USB Host and also appear on a computer as an HID Device/ Serial Port etc
As far as I know the fix function product here don't support to work as USB host.
The EFM32 with USB peripheral like EFM32GG (and other) support both host and device. You may need devlelop the firmware for it by yourself.
