Hi-speed USB transfer LPC4337

I would like to make a "high speed" data acquisition board using LPC4337. I have found vcom example, and while it does connect to the PC and shows max speed to be around 12Mbit/s, it only allows me to connect through serial port with speed up to 1843200 baud. Even then I get most of packets lost if I force the transfer in one bulk. VCom driver is probably badly written..

Before going into endeavour of debugging and fixing the vcom, is there any other way of getting higher transfer rates ?

I would need around 1MB/s, so closely to max theoretical of that 12Mbit/s.

HI Sven

Which usb interface do you work with? if USB0, it maximal is 12Mbps. if you want higher speed, use USB1 which is high speed USB device.

Have a nice day,
