Hi all -
I got the Silicon Laboratories CP2103-EB inteface kit from DigiKey. This is an adapter from a standard USB connection to provide a standard RS232 interface. It comes with an interface adapter board, a USB cable, an RS232 cable, and a driver disk. The kit works great and is reasonably priced.
I have been having a problem in trying to use two of these kits with my laptop simultaneously, though. When the first kit is plugged in, it is correctly enumerated and the Hardware Profile shows a COM port available. When the second kit is plugged into the USB, it has an error. If I exchange the two kits in plug-in order, the problem follows the second kit.
Has anyone used two of these kits in the same system? Is there a trick to getting it to peacefully coexist with multiple units?
I've tried the Silicon Labs website. They are no help at all. I have tried sending e-mails on multiple occassions and have had no returns.
Any help would be appreciated.
Dave
