I own a CanoScan LIDE 25 and, yes, it does support WIA!
The WIA driver is almost hidden in installation CD, in "X:\Canada\WIA" folder. Don't ask me why "Canada". :shock:
It isn't installed by default! You need to remove the TWAIN driver (in case you already installed it) and install WIA manually.
There's also a good documentation (README, Install Guide, User's Guide), so it won't be difficult to make it work!
If your installation CD doesn't have the WIA, try google: "canon lide 25 scanner wia driver", replacing "lide 25" by your scanner model. In my case, I've found out it is available for download in http://www.canon.com.au
Good luck!
