I have a requirement to provide an embedded microcontroller that will download data from two (dual) USB ports and then send the data to a MySQL database on the internet via a WiFi module (I plan on using ConnectOne's iWiFi Minisocket). I know the PIC 18F2550/4550 chips support a single USB port, but I don't believe there is a PIC chip that supports dual USB??
Has anyone on this forum ever done a dual USB application with one MCU? If so, would appreciate tips on doing so.
