Uncertified Windows Driver

OK, I am working on developing a USB device. I have created a custom windows driver for the device based on a pre-made Windows driver from my MCU manufacturer. The driver works fine on Windows XP, and Windows 7 (32-bit), BUT on my Windows 7 64-Bit machine, it will not let me use the driver. The driver will install just fine but when i go to the driver properties (in device manager) it says "This driver is not digitally signed by Microsoft" and it will not let me use it. I REALLY don't want to pay 100's of dollars to Microsoft and hours of time to get this driver certified (for several reasons). Is there any way I can get around this other than telling my customers to go back to XP??? PLEASE HELP!

You don't have to submit your drivers for WHQL certification. Microsoft only demands that your code is signed with a digital certificate. You can choose where you buy the certificate, GoDaddy sells them for 179 $ per year.

EDIT: Microsoft has a deal with Verisign: first year for 99$. https://winqual.microsoft.com/help/default.htm#obtaining_a_verisign_class_3_digital_id.htm

For testing purposes, you can enable the test certificate and self-sign the driver.

To actually release it in the wild, it needs to be digitally signed to run on 64-bit systems, and there's no way around this. What are your reasons for not wanting to go through the signinf process?
