Scanners not working via Citrix/Xenapps/Win Server 2008 R2

Greetings Folks,
we have several Windows Server 2008 R2 servers that deploy programs via Citrix Xenapps. Does anyone know any solutions/products that is compatible (via Citrix ) with the following scanners (in particularly Scansnap S1500, Scansnap s510, Scansnap s500, Visioneer Strobe XP450 scanner) amongst others (including HP Scanners). We would like all these scanners to be detected and working via citrix and then scan (and the data stored to our network drives via citrix).
This site software has advised that scansnap software is not compatible - does anyone have a solution please?????

On another note, any solution on getting Omnikey Smart Card Readers (model 3121) working via Citrix too -it is not installing/detected, I welcome any advice/solutions /products/solutions for this to too

Thanks in advance

[May you all be directed to Goodness]
