XA has limited USB redirection support.
Typically devices like USB mass storage, CD ROM, printers, etc. are mapped perfectly.
But devices that need a special driver don’t.
So I guess you signature pad needs a driver.
Your options would be:
– use XenDesktop and it should work directly
– use Wyse TCX for USB redirection. Culprint with this solution is, that there is no session security in XA and therefore each user on this server will see the mapped USB device. In other words: not useable for you.
– use Windows embedded
