When you log on to a cloud desktop by using an Elastic Desktop Service (EDS) client, you can connect peripherals that are connected to your on-premises devices such as your computer or Alibaba Cloud devices to the cloud desktop. The peripherals can be audio and video devices, storage devices, and printers.

Prerequisites

  • If you connect peripherals to a cloud desktop over USB interfaces, make sure that your on-premises device is equipped with a USB interface and the USB redirection feature is enabled for the cloud desktop.
    Note If the USB redirection feature is disabled in the policy that is associated with your cloud desktop, contact the administrator to modify the policy.
  • If you connect peripherals to a cloud desktop over Bluetooth, make sure that your on-premises device supports Bluetooth.

Background information

You can log on to cloud desktops by using the following EDS clients: software client on Windows OS or macOS computers, hardware client on Alibaba Cloud devices, browser client on web pages, and mobile client on Android or iOS devices. The peripherals that are available for different EDS clients are based on whether the peripherals can connect to on-premises devices.
  • Software client and browser client: computers.
  • Hardware client: EDS device series. Different series of EDS devices have different interfaces. You can view the interfaces on the EDS device buy page.
  • Mobile client: mobile devices. Only Bluetooth mice and keyboards are supported on mobile devices.
Cloud desktops support peripherals such as keyboards, mice, printers, and graphics tablets. The following table describes the peripherals that are available for cloud desktops.
Notice EDS is compatible with a wide variety of external peripherals. However, due to the diversity of connection interfaces, drivers, and protocols, some peripherals may not be supported. The following table describes the peripherals that are supported:
