There's no need for new drivers, on my Sindows 7 32 bit it works perfectly. I scan using the Twain driver, using Irfanview. The only thing is that I have to execute Irfanview as an Administrator, otherwise the scanner does not appear as a twain source. I think this problem is related to the fact that C:/windows/twain_32, which stores the drivers under the folder /CQL30, is only accessible to the administrator. I should check the permissions, but I'm lazy, so I simply execute with administrator roghts.
