This is a function I use for that:

Function Hex2Dec(strHex As String) As Long

'converts a hexadecimal number to a long
'if the prefix &H is not there, it will be added first
'-----------------------------------------------------

On Error GoTo ERROROUT

If Left$(strHex, 2) = "&H" Then
Hex2Dec = CLng(Val(strHex))
Else
Hex2Dec = CLng(Val("&H" & strHex))
End If

Exit Function
ERROROUT:

MsgBox "CAN'T HANDLE THE STRING: " & strHex, , "Hex2Dec"

End Function

You could then do:
MsgBox Hex2Dec(Mid$("FFFB: 00FFB125148", 7, 8))
