Using Putty to connect to a Cisco 4010 via built in usb port results i

[deoland32]

I'm attempting to connect to a Cisco 4010 network switch via it's built in usb port (which internally is a usb to rs232 adapter wired to the back of the console port).

I have installed the Cisco usb console drivers version 3.1

When I plug into the usb port, the little green LED that indicates that the console port has switched to usb does not light up.

When I run putty, and attempt to connect via serial connection to COM16 (the usb to rs232 in the cisco switch) I get: Unable to open connection to COM16 Opening '\.\COM16': Error 1450: Insufficient System resources exist to complete the requested service.

I have tried reinstalling the drivers to no effect.

I have 3 identical switches, which give me identical behaviour, all 3 new out of the box with no programming.

Changing the Baud rate makes no difference, not that I'm expecting it to as the issue seems to be COM16 doesn't exist or similar

my guesses are:
- your system (or terminal app) does not accept higher then COM15 
- you may not need to install the Cisco serial device driver separately anymore,
   the correct driver is loaded from the usb console port
- com16 is not the correct com port
   In Putty you select the com-port manually 
   in TerraTerm you can select the active  com ports from a drop-down list, this prevents mistakes

-> first go to device manager and check the active com ports
if that seems correct then:
- in device manager enable disconnected devices
- remove some (or all) USB com ports
- reconnect the switch and monitor what com port is created
- start your terminal program and select above com port

Try to run PUTTY using Administrator privilge,

or plus the usb to rs232 adapter to another USB slot on your PC,

or using another Terminal such as SecureCRT or MobaXTerm.
