A newer TWAIN DLL will not solve the problem. The Data Source Manager (TWAIN_32.DLL) is merely the middle man in capability negotiation.
CAP_DEVICEEVENT can only be supported by a Data Source (HP’s in your case). From your post it appears HP has chosen to not support it. According to the TWAIN specification, CAP_DEVICEEVENT is not a required capability.
What event are you attempting handle? Maybe there’s another solution to the problem you’re having.
