Looking at the INFs they were written in normal Intel fashion and even making some modifications to strip down to Windows 8.1 did nothing. Digging through the SCCM logs was not a ton of help either. AdminUI.Log, DriverCatalog.Log, SMSAdmin.Log, Setupapi.app.log, you name it. All just said the same thing, driver not applicable. Those actually gave an error code of 0x80070661.
Turns out the issue is due to our Site Server being on 2008 R2. Specifically with the OS. The signing in these drivers is using a newer method thats not native in 2008 R2. Microsoft released KB3025419 which states to install KB2837108 and KB2921916 to update the OS to support the newer signing method in ConfigMgr. Coincidentally both this KB and the Toshiba device came out at the same time. After applying the hotfix and restarting (not required but the KB states to do anyway) we are now able to import these newer signed drivers and image the Toshibas up successfully and quickly.
