19539. Firmware 4.7.1 removes a restriction that prevents enumeration of USB devices assigned with a Vendor ID (VID) of 0.

16066. Some Samsung NC220 and NC220P zero clients with certain memory hardware do not work reliably when powered by the AC adapter.



Key Known Issues:

10370. Zero clients and Remote Workstation Cards will not fetch DNS SRV records (pcoip-broker, pcoip-tool, pcoip-vcs) that were added after the endpoints being booted. If the records existed before boot time, the records fetch properly. Workaround: Reset the zero client or Remote Workstation Card in order to fetch the added DNS SRV record.

9573. Persistent Auto Connect timer stops when calibrating a touch screen on the OSD. Workaround: Click Cancel to close the timer and manually connect again.

9398. Occasionally when a VMware Virtual Machine (VM) with a PCoIP smart card component installed is connected to a PCoIP zero client with a smart card reader. The user opens a RDP session from the VM to another PC and performs some smart card actions inside the RDP session. If the RDP session ends while the smart card is being accessed then smart card applications on the VM freeze and are unable to access the smart card. Workaround: Disconnect and reconnect the smart card reader to unblock the smart card applications.

14409. If you log off a Win7-64 View session with a zero client during an active Logitech 9000 video session the zero client can freeze at a black screen. Workaround: Power cycle the zero client or disconnect the VM session via the zero client disconnect button or the CTRL + ALT + F12 shortcut if enabled.

P2000. On rare occasions, USB peripherals (HID devices) disconnect randomly. Workaround: Unplug and plug in the USB cable from the zero client or power cycle the zero client.

20968. Enhanced logging levels not set correctly on Tera1 zero clients. When USB enhanced logging is selected in AWI it shows Unified Communications in the event log. When Video enhanced logging is selected in the AWI it shows USB in the event log. The only way to obtain enhanced Video logging is to roll the firmware back to 4.6.0 or earlier.


9418. Customer reports of PCoIP devices crashing when many devices are simultaneously running on the fall-back IP address.  Workaround: set the Enable Static IP Fallback to false via Management Console.

20784. OSD artifact in a rare case where there is a double press on the zero client connect button.
