The SMBus is usually for system management communications between BIOS and devices like fans, batteries, chassis intrusion, laptop sensors, etc. I've seen some PCI cards that had SMBus extensions, but they weren't required, and I've never seen a card reader or USB port that was not on the USB controller bus as a hub or root device - if all of your USB buses are working, you should be fine. Also, the SMBus is an interrupt bus, whereas the USB bus is a polling bus.

@LittleRed

Usually windows dosn't load a driver for SM Bus.

Example from machine.inf

%PCI\VEN_1022&DEV_746A.DeviceDesc% = NO_DRV,PCI\VEN_1022&DEV_746A ; 8111 SMBus 2.0 Controller

; Do-nothing section used to avoid "Unknown hardware" installation prompts.

Does this refers to SM Bus controller or flash drive devices?

This reminds to a Realtek network card.

Does flash drive devices work at your machine?

Does device mangager list a strange device?

Goto device mangager, details. Which HardwareID goes to this device?

Some systems require the proper SM Bus driver to be installed for usage of devices on the USB Bus. A lot of notebooks nowadays will reroute some of the integrated devices through the USB Bus as well. A common symptom of a corrupted or missing SM Bus driver is when you plug a mouse into a USB port, Windows detects it as an unknown device and you have to manually install its driver.
