I just purchased a USB to Mini-USB console cable to use with the 2960s switches we just bought. I download the current(?) driver Ver. 3.1 loaded it on my Win 7 64-bit laptop. It installs ok but when I try to use it with Putty, Putty comes back saying it can't access the port. I noticed the driver says it's for Win XP and Win Vista. Is there a newer driver for Win 7? Any other ideas?
The USB driver required will depend on the UART designed into the product.For the Catalyst Micro Switch CMICR (which uses the USB Type B micro connector for console), this driver for Win 10 can be obtained from Silicon Labs: -to-uart-bridge-vcp-drivers?tab=downloads(CP210x Windows Drivers with Serial Enumerator)After installing the driver, connect the USB cable to the switch and laptop.The Win Device Manager will show:
12. Finally, You will see "USB Serial Port "change to "Cisco Serial (x)". Check that the driver proider is Cisco and NOT Cypress. Also, check the Cisco Serial (COMx) port settings. Try Connect to Com port X. it should work, now.
I just downloaded this universal driver from the chip's manufacturer and it works right out of the box on Windows 10. Maybe it wont work on other devices that have different chips, but hey, i think it is worth a try.
My cisco driver com3 port stopped working on windows 10, so I uninstalled the cisco driver. After I rebooted, and reconnected the usb console cable, the native windows usb-serial driver loaded, and a new com3 port appeared. That port works just fine with securecrt with standard 9600 baud settings, so I guess we don't need the cisco driver. fwiw.
To download the driver you will need a CISCO account login... update your account with your address... accept user agreement... apologies to coworkers for numerous expletives lodged during ridicules endeavor.
If you own an older laptop and there is no USB port, you might want to install the Cisco USB console driver. This software is free to download and install, and you can get it by clicking on the free download link. This way, you can download the driver without having to pay or wade through a bunch of spammy offers. After downloading the software, reboot your computer to apply the changes. Now, your laptop should be able to use the console.
The Cisco USB console driver is required for a computer to connect to a Cisco router. The driver is available for download on the Cisco Download Software website. If you have a console cable, you need to install the driver for it. It is a software component and is not tied to any particular console cable manufacturer. After you download the driver, you need to install it on your PC to use it. You can download it from the Cisco website in two ways: through the Cisco router itself, or by visiting its dedicated website.
To install the driver, you should install it as an administrator. The driver files are the same as those for version 126.96.36.199. However, if you have problems with the driver, you can download the updated version and try it out. It is highly recommended to install the upgraded version if you are not yet using this version. Also, it may not start the data communication process if you remove the USB device while it is transmitting data.
You can get this driver from the Cisco website or install it manually on another PC. Then, simply connect the USB console port to your PC and follow the installation instructions. You may need to change the COM port if your PC is using a different one.
To install this driver, go to the Cisco website and download the file. Make sure to have a USB-A to Mini-B cable. Also, you need a fat16 drive. You may also need to modify your terminal emulator software to recognize the file.
After downloading the driver, make sure that you agree to the license agreement before you proceed to install the driver. The downloaded file is in zip format. Open the file and double-click the setup option.
To connect to the Cisco switch via a serial cable, you will need to purchase a USB-Serial Adapter. After installing the software, you can connect the Cisco switch to your computer using the console cable.
The first step is to plug your laptop into the console port on the Cisco device. You can start a terminal session by clicking Applications>Utilities>Terminal. Then, open the terminal window and type ls -ltr to list all your USB devices in reverse order.
In the list, the console cable should be the last option. Once this is done, you can start running the regular Cisco commands. To disconnect from the terminal session, press Ctrl-a followed by Ctrl-d.
When you are having a problem installing the latest drivers for your Cisco USB devices, you may want to try using the built-in Utility. This utility can find all the devices and their associated drivers, and install the latest drivers for you.
A reinstall of the driver is another possible solution if your computer has encountered this error. The process involves uninstalling all devices listed under the Universal Serial Bus controller hardware category and then installing them again.
Before using the updated version of BHT, it is recommended that you download the latest version. Earlier versions of the driver did not work properly with this feature, which caused the data communication to fail if you removed the device. The updated version 188.8.131.52 was released on May 29th.
You can access the CLI on a configured or unconfigured switch by connecting the RJ-45 console port or USB console port of the switch to your PC or workstation and accessing the switch through a terminal emulation program.
If your switches are stacked and there are multiple console connections to individual switches in the stack, the initial setup dialog box appears at the console where you first press Enter.
For years I have been wondering when Cisco would activate the USB ports on their devices. I have been hoping for all kinds of USB functionality to routers, switches, firewalls but Cisco has been slow to unlock the power of these USB ports. Wouldn't it be cool if you could connect the myriad of USB devices to a Cisco router to further the list of amazing things you could do? Cisco has started to put mini-USB ports on their devices to allow for console port connectivity.
I am hoping that this new method continues to be spread to other devices. I also hope that Cisco will enable all of the USB Type-A ports on their other devices for similar connectivity. For years I have hauled around two console cable sets. Because I often connect to multiple devices at the same time, such as redundant supervisors on 6500s or to two supervisors in redundant 6500s or VSS, I need two serial cables. Here is a picture of one of my typical USB cables. I use a Keyspan USA-19HS USB to serial adapter. I realize that this is expensive but it is the most reliable and its driver seems universally accepted by laptop operating systems. Note that the end on the light-blue console cable has been replaced and a yellow boot added because of excessive wear. You know you have logged into a lot of Cisco routers when you wear out the RJ-45 connector on the end of your favorite console cable.
You still need to install a driver on your laptop to use the USB interface as a serial communications port. Don't worry that this link shows the download location for 3900 ISR G2 routers. The same utility works for the entire ISR-G2 line. The latest version of the USB Console Software is version 3.1 The filename of the software is "Cisco_usbconsole_driver_3_1.zip" and the current version was release on Jan 20, 2010 with a file size of 14692.83 KB (15045453 bytes).
Once you install the driver you need to create a connection using your favorite terminal emulation software. My favorite one happens to be SecureCRT from VanDyke. You need to set the terminal emulator to use the proper COM port that is being used by the USB port on your laptop. Then you set the serial communications to the old-reliable standard: 9600 baud, 8 data bits, no parity, and 1 stop bit, no flow control. However, I have been told that these console ports can be run up to 12Mbps but the baud rate of the serial port can only go as high as 115,200 bps. That could have come in handy many moons ago when I had to upload IOS files using XMODEM.
The other caveat is that the Cisco devices are still coming with the traditional RJ-45 console ports. You can use both of these ports but only one will allow for commands to be entered. It appears that the USB port trumps the RJ-45 port. It is like the USB port is the default console media-type. Since the USB port takes precedence over the RJ-45 port then you will want to set the inactivity timeout for the USB port so that if it is unplugged that the RJ-45 port can become active again. This is done with the following command.
I believe that the usb-inactivity-timeout command is not supported on 2900 series routers. To restore USB console port connectivity after the timeout period then you will need to unplug and re-plug the USB port to re-activate the USB console port connection.
For security reasons you may want to disable this USB port. In this case you can configure the device to only allow console connectivity with the RJ-45 port. This can be performed with the following commands. 2b1af7f3a8
