How to connect Usb-Cardreader to remote Server

We have a physical server (2003) with an attached card reader.
This server will be virtualized. It is not a local USB port available.
Other servers with usb dongles are already virtualized. Here, the connection worked for Anywhere USB/14 without problems. What steps are necessary in order to connect the card reader to the usb/14 Anywhere? additional drivers are needed?
Thanks in advance
