Dell ThinOS 2211, 2208, and 2205 Release Notes

Known issues and Limitations with PowerMic devices

• Nuance PowerMic sound dictation does not work properly in PCoIP sessions. This causes the Dragon Medical One (DMO) software to stop responding after some time.
• Hot plugging in or plugging out the PowerMic device when it is working may cause the DMO software to stop responding. As a workaround, relaunch the software.
• It is recommended to use full redirection of the whole device in Blast and Citrix sessions. If you split redirect some buttons in Blast and Citrix sessions and plug out and plug-in PowerMic, the device is not recognized. In Blast sessions, you must also disable Bluetooth redirection or it ThinOS works abnormally.
• PowerMic stops working in the DMO software inside VMware PCoIP sessions after inserting a USB drive to the thin client. This issue occurs only if the USB drive is redirected. As a workaround, use USB disk Map settings instead of USB disk Redirection.
• PowerMic does not redirect to VMware PCoIP sessions when you do the following in sequence:
  1. Sign off from the Broker agent without closing an application.
  2. Disconnect and connect PowerMic to a different USB port.
  3. Sign into the Broker agent again.
• PowerMic does not work in DMO software after disconnecting PowerMic II and connecting PowerMic III when a VMware PCoIP session is open.
• The mouse pointer is not displayed in VMware PCoIP sessions when using PowerMic As a workaround, sign out and sign into the Broker agent.

Workaround

• If you are using Power Mic 4, you must enable Allow USB Imaging Family Device and add 0x05540064, NoDriver in vUSB Force Redirect. To add the parameter, go to APT > Advanced > Session Settings > Session Settings.
