使用 Putty 通过内置 USB 端口连接到 Cisco 4010 会导致错误 1450。使用 Windows 10 build 19044
我正在尝试通过内置 USB 端口(内部是连接到控制台端口背面的 USB 转 RS232 适配器)连接到 Cisco 4010 网络交换机。
我已经安装了 Cisco USB 控制台驱动程序版本 3.1
当我插入 USB 端口时,指示控制台端口已切换到 USB 的绿色小 LED 没有亮起。
当我运行 putty 并尝试通过串行连接连接到 COM16(cisco 交换机中的 USB 到 rs232)时,我得到: 无法打开与 COM16 的连接 打开“\.\COM16”:错误 1450:系统资源不足,无法完成请求的服务。
我尝试过重新安装驱动程序,但没有效果。
我有 3 个相同的开关,它们具有相同的行为,所有 3 个都是开箱即用的新开关,无需编程。
更改波特率没有什么区别,并不是我期望的,因为问题似乎是 COM16 不存在或类似
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

在一位同事的帮助下,我们使用默认的 usb 转 rs232 驱动程序而不是我安装的 cisco 驱动程序,将问题范围缩小到了 Windows。当我尝试在虚拟机内使用 putty 并且它有效时,出现了一个重要线索,而在主机操作系统上我仍然收到错误 1450。
我们必须完全卸载所有驱动程序,重新启动,手动重新安装驱动程序,重新启动,然后再次尝试 USB 连接。
这里的最后一条评论描述了它:

我将复制解决方案到这里,以便为下一个遇到相同问题的人更轻松地搜索解决方案。
对于 WIn10,请安装 Cisco_usbconsole_driver_3_1.zip 中的 setup(x64).exe。
检查 Cisco 串行 (Comx) 是否使用正确的驱动程序提供商(应为 Cisco)。不要使用赛普拉斯驱动程序。
设备管理器
要更新驱动程序,
卸载 Cisco 驱动程序
首先,断开蓝色的 Cisco USB 控制台电缆。使用 Windows_64 文件夹中的 setup(x64).exe 重新安装思科 USB 控制台驱动器,该文件夹是从文件 Cisco_usbconsole_driver_3_1.zip 中提取的。
重新启动电脑
打开设备管理器以观察驱动程序安装情况。检查您是否看到“Cisco USB 转串行适配器”。如果您没有看到它,请重复上述步骤。
如果您看到上面的“Cisco USB 转串行适配器”。那么
更新驱动程序
单击“更新驱动程序”,然后单击“浏览我的计算机”以获取驱动程序软件。
选择驱动程序
With the help of a colleague, we narrowed the issue down to windows using a default usb to rs232 driver rather than the cisco one I had installed. The big clue came when I tried using putty inside a VM and it worked, while on the host OS I was still getting error 1450.
We had to compeletely uninstall all drivers, reboot, reinstall drivers manually, reboot, then attempt the usb connection again.
The last comment here describes it:

I will copy the solution across to here, for easier search of the solution for the next person who has the same issue.
For WIn10 , install the setup(x64).exe from the Cisco_usbconsole_driver_3_1.zip.
Check that the Cisco Serial (Comx) is using the correct driver provider which should be Cisco. Don't use the Cypress driver.
Device Manager
To update the driver,
Uninstall Cisco Driver
First, disconnect the blue Cisco USB console cable. Reinstall the Cisco USB console drive using setup(x64).exe from the Windows_64 folder which was extracted from file Cisco_usbconsole_driver_3_1.zip.
Reboot PC
Open device manager to observe the driver installation. Check that you see "Cisco USB to Serial Adapter". If you don't see it repeat the above steps.
if you see above "Cisco USB to Serial Adapter". then
Update Driver
Click UPDATE DRIVER, then Browse my computer for driver software.
Pick driver
