Wyse ThinOS and a USB document Scanner -PCoIP
Hi Guys,
I have a WYSE 3040 Thin client running ThinOS 8.6_013.
I am using PCoIP to connect to a Windows 7 desktop with a document scanner connected via USB to the thin client. The scanner never works from the Wyse thin client but works fine if I use the Horizon client from my physical laptop running Windows with the scanner plugged in.
This definitely has to do with a Wyse configuration - I have tried to tick multiple different options under the global connection settings
- USB Device redirection ticked
- Nothing excluded
- everything else unticked
Thoughts? (Tried several Wyse clients - same results)

Yes - the driver has already been installed - on the windows desktop but not on the Wyse client.

Hi,
Does the scanner require a driver?

If the scanner is a TWAIN scanner it likely will NOT work. Twain is a windows only feature, which would explain why it works under your windows workstation.
You may be able to tinker with Disabling USB redirection for the protocol, and do a forced redirection using the method below. You would need to monitor the event log for the VID and PID specific to the device when you plug it in.

This was true at the time that buffalobound wrote this post so I did want to provide an update that the TWAIN Working Group has released a RESTful API version of the TWAIN driver called TWAIN Direct, https://twaindirect.org. The intention of the TWAIN Direct project is exactly the issues described in this thread, which is to offer stable document scanning connectivity with Thin Clients in environments such as PCoIP. TWAIN Direct uses network interfaces, instead of USB, so this is why you can use PCoIP.
