I have an existing device A built with a TUSB3410 and an MSP430F148, speaking with a Windows PC through TI driver and virtual serial port, classical architecture. Now I want to replace the PC by a new device B based on an MSP430F248 and a USB host chip (maybe Vinculum from FTDI) to control the device A through USB. Of course I cannot modify the existing device A (already deployed 500 times).
Do you have any advice for the USB host chip ?
Would the Vinculum USB host chip handle the TUSB3410 USB slave ?
How can I emulate the UART serial port on device B ?
Tx for help
