This is a tuff one with external scans. All i can say is enable generic usb, the. Right up or create custom batch files for the piv and vids. Enable generic to dword 0000001.

Be aware that Generic USB Redirection will increase your bandwidth. Are the users working with reliable internet connections? I remember a PoC where scanning a document with generic redirection was taking about 95 seconds. With TWAIN it was maybe 15? Going into a project with unsupported devices will sooner or later be a big issue. I wouldn’t go 100% on native usb redirection here. Is this a Desktop or Published App environment? What about scanning the documents local and then copy them with regular file transfer from the Local Disk into the session? I am not saying Generic USB redirection will not work -> Try it and weigh if you have a good feeling with it -> Citrix support is again a thing... if it’s working everything is fine but If not 👎🏻 I even have seen clients burning DVDs via NS gateway and an external usb burner 😉

Thanks. Generic USB redirection seems to be NOT an option because of weak upload for most of the users (2-6Mbits/s). Given my challenge with scanning, Citrix seems to be the WRONG choice. 😢🥺

Oh ok, dont want that then. Well is twain is hit more miss. Then doing the file upload from the client to the session seems like a good idea. But you have to train them. Some environments that hard once the user does something over and over. But it gets somewhat confusing, if the scanners are usb and twain is enabled. I assume it used twain settings Twain_32.dll instead of actually usb generic?

File transfer is not an option. Too complicated especially compared to VPN where all works fine with scanning via apps without any issues.

Tuff one Arthur.
Some scanners simply will not work with "optimized" some scanners aren't terminal server aware either. On one that isnt working, do u see it in the devices on workspace or reciever? Receiver -> Connection Center -> Devices -

Many “random” issues. Hopefully redirect via WIA will solve it. Unfortunately it’s still not available in Citrix :-((((
r
Understand. Yea i Hope its works out for u. I hate the ramdom issues. Stressful at times
a
Most common issue: scanner is working however there is no any scanning results :-(
r
Oh man thats so frustrating.
I looked up wia for citrix. I see this alot http://www.scanner-for-remote-desktop.com/ Seems like a solution. But always more money 😤
I used scanning with generic usb when i had tons of issues. I have a dsl connection where i live and scanned docs take about 20-30 seconds.but that was on the 7.6 platform
a
20-30 seconds on one page is way too long. Scanning is one of the basic tasks for users. Users submit applications which they sign and then must be attached in the application. I will check 3rd party software. Thanks
r
It is. Cool. Good luck Arthur. Let me know when u get it straightened out.

I think the software is from Fabulatech. 99.95$ per user sounds like a high price. Tell us if it’s working for you. I have played with the USB redirection of Fabula about 1.5 years ago because some 3D Connexion mouses didn’t work via Citrix Generic redirection -> Same result
r
High indeed

Good to know
