I am trying to connect the router console port(which uses
rollover cable with RJ-45 on one side and DB-9 female on
the other) from my PC's USB port. I bought the cable with
one end DB-9 male connector and the other is USB. As soon
as I connect the USB cable in it comes up with the error
the device may not work properly. I check the device
manager and under the USB DEVICE error "Code 28 Error
Message and a Yellow Exclamation Mark Next to a USB
Device in Device Manager" I have updated my computer with
all the microsoft updates still no good.
pls help.

You have three connector types there. The only router console I have
ever logged into was accessed by connecting a DB-25 to the console and
connecting an RJ-45 to my laptop. I then logged in through HyperTerminal.

For your router console, are you saying the RJ-45 goes into the router
console and then you are trying to connect the DB-9 converted to USB to
your computer? Have you tried it the other way around? Also, have you
tried it without the DB-9 to USB adapter?

Sorry I'm not much help. Maybe someone here has their CCNA and wouldn't
mind chiming in
