The WHQL System Suspend Resume Test fails for the USB driver I'm testing, but only on WIN 7 64-bit. When that client resumes, the device is allocated to a different USB Hub/controller and can't be found. This does not happen in WIN 7 32-bit or Vista 32-, 64-bit. I've even tried disabling all USB controllers except for the one the device is on and it still fails the test.
