Dell 2407WFPb card reader

Hi,

    I am having trouble using a 8GB SanDisk Memory Stick Micro (M2) in the card reader on my Dell 2407WFPb monitor.  It seems to work fine for capacities of 4GB and under but when I put in a 8GB SanDisk Memory Stick Micro (M2) using the appropriate adapters (M2 and Memory Stick Duo Adapter) it says that the card is unformatted.  When I try to format it under Windows XP it will only let me format it at a capacity of 3.51GB.  Now I know that the card is working fine as I have used in on my Sony Ericsson phone and in a PSP, have formatted it at the 8GB capacity and used it.  I can't find the specifications for the 2407WFPb but the specifications for the 2407WFP indicate that it can handle a 32GB Memory Stick Duo.  My question is, should the card reader be able to handle this?  Is there a driver or firmware update that could fix this?  Are the specifications for the 2407WFPb the same as the 2407WFP?

Thank you.
