Connecting multiple i.MX53 QSB devices to the dev m/c

[GeethanjaliBala]

Hi,

I want to connect multiple i.MX53 QSB devices to my dev m/c(Windows). But when I connect the third or sometimes 4th device, there is a cras observed. And all the devices that are connected also get the same serial number. Has anyone tried this? Can you shed some light on this.

You mean USB connection or Serial connection?
