The ISO image has been created from the original CD provided in the package. The driver itself (umssfdik.sys) appears to be generic from the Windows 98 DDK (sample Q257751). It is not signed and it claims it is manufactured by Microsoft. The version number probably refers to the sample and not to the product. I have not checked that it works because I am running Virtual PC and it does not allow me to access host USB. I shall check it as soon as I sit down at a Windows 98 system with USB again.
