USB Drive Not Recognized After Re-boot

I have a Windows 7 64-bit system. I connected my Maxtor 500Gb USB drive while the PC was on and it recognized the drive using the default windows driver. Seagate, which owns Maxtor, does not have a 64 bit driver for this drive. Seagate and Microsoft say the drive should work with the windows driver. It was working beautifully. Then I re-booted my system. Upon Windows re-start, the drive came up as "USB Device not recognized". In Device Manager it is a yellow icon next to "Unknown device". I removed the USB cable and re-plugged it to no avail. I then removed the drive's power cord and plugged it back in...the drive was instantly recognized again.

What is happening on a re-boot to mess up the USB connection? How can this be resolved? I don't want to have to pull the power cord on every re-boot...
