I am wondering if you get viruses from device drivers installing from a USB (from the automatic installation if an unknown USB device has been plugged in) in Windows.

Hello Mutantspidermonkeys -
Are you downloading from a "crack / scam" site, or the Genuine makers site ?

Was the USB Flash Drive "cleaned" first ? Do you know how to clean a Flash Drive ?

 

The rest of the question should be answered by reading the above (I believe).

 

A clean USB Drive and Genuine downloads present no problems .......

 

Thank You -

That means "yes". You can infect your computer from a pen drive. And, unfortunately, it isn't always clear if any given web site is actually "safe" or not even if the site is generally considered legitimate. Lots of sites are compromised. Personally, I use ClevX on my pen drives for a bit of extra security. I think noknojon oversimplifies the issue of secure downloads.

A flash drive (usb, pen, thumb, jump) infection usually involve malware that modifies/loads an autorun.inf (text-based configuration) file into the root folder of all drives (internal, external, removable) along with a malicious executable. When removable media is inserted (mounted), autorun looks for autorun.inf and automatically executes the malicious file to run silently on your computer. For flash drives and other USB storage, autorun.ini uses the Windows Explorer's right-click context menu so that the standard "Open" or "Explore" command starts the file. Malware modifies the context menu (adds a new default command) and redirects to executing the malicious file if the "Open" command is used or double-clicking on the drive icon. When a flash drive becomes infected, the Trojan will infect a system when the removable media is inserted if autorun has not been disabled. Keep in mind that autorun.inf can also be a legitimate file which other legitimate programs depend on so the presence of that file may not always be an indication of infection.

What quietman7 posted is the most common method of malware infection attack. Also keep in mind that a USB flash drive does have a "master boot record and a partition table" so it can be infected with master boot record malware. https://en.wikipedia.org/wiki/USB_flash_drive#File_system

Connect a USB flash drive to your PC so it's mounted. Use any of the standalone Master Boot Record (MBR) tools to view the MBR.
