What do I do if the toolbar on my cloud computer does not have the Devices option?

The Devices option is not provided for non-ASP cloud computers that run Linux Ubuntu if you connect to the cloud computer and update Linux Ubuntu.

In most cases, the USB redirection feature determines whether you can use the Devices option on cloud computers. If the administrator enables the USB redirection feature for your cloud computers, the Devices option appears. Otherwise, the Devices option does not appear. If the administrator has enabled the USB redirection feature but the Devices option still does not appear, you must contact the administrator. The administrator can perform the following operations based on the Linux Ubuntu version:

• If the cloud computer runs Linux Ubuntu 18.04, the administrator can change the image of the cloud computer to update its OS in the WUYING Workspace console, and you do not need to manually update the OS on the cloud computer.

• If you need a cloud computer that runs Linux Ubuntu 20.04, the administrator can use a cloud computer template in which the OS is Linux Ubuntu 20.04 to create a cloud computer.

What do I do if a Windows cloud computer fails to connect to a printer and the 0x0000011b error is reported?

You can connect an on-premises printer to a Windows cloud computer by using USB cables, and the printer is shared within a local area network (LAN). If other cloud computers want to access the printer, they must access the cloud computer that shares the printer over a specific IP address. When the printer is connected, the message "Windows cannot connect to the printer" and the 0x0000011b error is reported. In this case, you can perform the following operations to add a registry on the cloud computer that shares the printer and the cloud computer that wants to access the shared printer:

1. On the cloud computers, press the shortcut keys Win+R to open the Run dialog box, enter regedit, and then click OK to open Registry Editor.

2. Go to the directory HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print in the registry editor and press Enter.

3. Right-click a blank area in the panel and choose New > DWORD (32-bit) Value.

4. Specify a name for the registry file that you created in the previous step as RpcAuthnLevelPrivacyEnabled and change the value to 0.

What do I do if the printer manufacturer does not provide a printer driver for Windows Server?

In most cases, printer manufacturers provide drivers for Windows 7, Windows 10, and Windows 11, and some manufacturers also provide drivers for Windows Server 2016 and Windows Server 2019. If the printer manufacturer does not provide a printer driver for Windows Server 2016 and Windows Server 2019, you can use the following solution to resolve the issue:

Solution

1. Obtain the driver for Windows 10 from the official website of the printer.

2. Install the driver on your cloud computer.

   • If the driver can work as expected on the cloud computer, the driver is compatible with Windows Server 2016 or Windows Server 2019. Then, you can use the printer on the cloud computer.

   • If the driver cannot be installed, you must find the path of the directory where the files of the driver are saved to install the driver.

     1. Decompress the obtained driver package on the cloud computer.

     2. In the property panel of the driver that you want to install, click the Advanced tab and click New Driver.

     3. In the panel that appears, click Have Disk, select the path where the driver is decompressed, and then follow the on-screen instructions to proceed.

        Note

        If multiple printer drivers are available after decompression and you cannot determine which driver to install, you can check the name of the printer driver that is used on your local computer and then select a path to install it.

How do I use a UKey device on a cloud computer?

UKey devices fall into the following categories: human interface devices (HIDs), MASSSTORAGE devices, and composite devices of HID and MASSSTORAGE. The following items describe how to use each of the preceding types of UKey devices:

• HID

  By default, a device of this type uses USB redirection. When you connect such a device to your cloud computer, use the default settings.

  If this device is not displayed in the peripheral list on your cloud computer, the device may be included in the blacklist because the cloud computer failed to obtain its name. In this case, you must perform the following operations to add the device to the whitelist.

  Note

  In this example, a Windows client of Alibaba Cloud Workspace V6.0 is used. The actual client version that you use shall prevail.

  1. On the card display page of the client, click and select Settings.

  2. In the Preferences panel, click Peripherals.

  3. On the Local Peripheral tab, find the device that you want to manage and click Whitelist in the USB Redirection Blacklisting/Whitelisting column.

  4. Unplug the UKey device and plug it again. Alternatively, reconnect to the cloud computer.

• MASSSTORAGE and composite devices of HID and MASSSTORAGE

  You cannot determine whether a device is a UKey device or another type of storage device from the appearance of the two types of devices. By default, these two types of devices are connected by using device redirection. However, device redirection does not take effect for UKey devices. To resolve the issue, perform the following steps:

  1. On the desktop of the cloud computer, wake up DesktopAssistant, click Settings and then Peripherals.

  2. In the Peripherals dialog box, click Advanced Peripheral Settings.

  3. In the Advanced Peripheral Settings dialog box, click Unknown Device.
