Hola, I have a Satellite L50D-AST3NX1, which was installed with windows 8.1 but I have downgraded it to windows 7-32 bit. I have found most of the drivers that were listed as missing but their are 2 that i'm unable to find. The missing drivers are the sm bus controller, and universal serial bus controller. Any help please.

Thanks for your help in advance.

Thanks for your reply. Do you know particularly what name the drivers would be under because I installed the driver listed in the first link you have for the USB and that did not do anything for the universal serial bus controller. Still searching for the sm bus controller too.

Well to help you I need more infos, like SN and/or model number. In device manager, where you see unknown device, look for device id, and try to google it. Try to install Management Engine, some times that helps.
What drivers did you have installed so far?

Unfortunately, no information is available in the properties for these two devices as its unknown. I do have screenshots I took before downgrading of what devices I had listed in the 8.1 but i'm unsure as to how to add them to this message so I saved them here:
