Why can't both my devices support 1650x1050?

I have 2 USB to VGA adapters which externally identify themselves as WS-UGA12D1. They were bought at different times and the external serial numbers are significantly different (WS000300097 and 3000400208).

The debug tool however, identifies them as follows:

Serial Number: USB_0198-450359
FW Version: 00.04
Product: WS Tech USB-DVI
Vendor: DisplayLink
Status is (F0005000):ASIC
Library: 0x0106, SVN status: Clean, SVN Revision 9971

Serial Number: USB_500365
FW Version: 00.15
Product: WS Tech USB-DVI
Vendor: DisplayLink
Status is (F1005001):ASIC
Library: 0x0224, SVN status: Dirty, SVN Revision 12991

Now, using the same display (Dell 2009W, 1650x1050 on DVI connection), the USB_0198-450359 with apparently older firmware (0.04) supports 1650x1050, while the other device will only display 1440x900 on the same monitor.

How do I get them both to display 1650x1050? Can I change the firmware? is there a 'force' option? Or is it a hardware difference and I'm just stuck with it unless I get a newer device?

I'm running 5.4b1 under Windows 7.

Thanks.
