Abstract:
Techniques for implementing improved USB redirection of USB HID class devices are provided. In one set of embodiments a client system can receive, from a virtual desktop running on a server system, a poll message directed to an HID interface of a USB HID class device plugged into the client system and identify a polling thread associated with the HID interface. The client system can further save a copy of the poll message in the polling thread and initiate local polling of the HID interface, where the local polling comprises providing, via the polling thread, the copy of the poll message to the HID interface.
