Hello guys, I am wondering is LPC-H2214 from here http://optimal-microsystems.com/store/index.php?cPath=24 has USB host? It is not clear to me what "USB-RS232 virtual port" means. I am looking for ARM7TDMI based microcontroller with USB port so I can plug USB peripherals into it and would like to have eCos running on it. Can anybody help? Best regards, Dmitry.
Does LPC-H2214 have USB host?

Can anybody help?Its a USB slave: if you look at the schematic you can see that its an FTDI FT232BM. So this lets you connect the board to your PC via USB but communicate with it using serial protocols. The HH2214 will just see a serial port. Andrew

You can get an Atmel AT43USB380 Development Kit which has an ARM7 (AT91R40008) and a USB host. -- Best Regards Ulf at atmel dot com These comments are intended to be my own opinion and they may, or may not be shared by my employer, Atmel Sweden.
