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.

Since there has been no response on this issue, I assume no one else is
using these devices in this kind of a configuration.
My solution to the problem was to have to get a 2-port com device interface
attachment which plugs into a single USB port. The cost is just a little
higher than one of the Silicon Laboratories CP2103-EB devices, also. This
has the added benefit of freeing up one USB port while connecting one or two
RS232 devices.
I am totally disappointed in the lack of response from Silicon Laboratories
on this issue. I will never use any of their products in the future, either
at home or at work. I will also recommend to anyone else to not use their
products. You will not get any technical support...

I did not know of that utility. I did try to change the com port settings
from Windows by changing the properties but it was unsuccessful.
I have since then purchased a dual-port serial interface which runs directly
from the USB port. It works quite well. It also frees up a USB port, which
is additionally beneficial.
Thanks.
