Lots of folks won't like this answer but I'll give it anyway lol.
I've been stuck for drivers a few times and what has 'bailed me out' is a program by Advanced System Care called Driver Booster 4. The free version is fine. I've never used it on a Toshiba but it has done the magic on other Laptops. It lets you pick and choose which of the recommended driver updates it wants to do so and ... it allows you to rollback anything it does update so .... not much to lose by trying it.
Robert, I tried the software, but it didn't work. In addition, this software kept trying to install additional applications on my computer. I hate software that keeps trying to "sneak" software on your computer. I am concerned that this software has installed spyware or adware in addition to the Driver Booster, which did not even work! I will keep my eye open when I use the notebook. If I see something suspicious, I back up my data and then I will do the Windows 10 "Reset" function and get rid of everything.
Unfortunately, the only answer is to continue using this notebook without a USB driver.
