RE: Dell Inspiron 11 3137 - DW1704 Wi-Fi + BT Driver = BCM43142 Windows 7


I may be able to help. I don't have PCI device codes handy, but here's what I figure:

1) USB 3.0 driver - I got mine from the Intel Downloads website. Works perfectly. Intel® USB 3.0 eXtensible Host Controller Driver for Intel® 8 Series/C220 Chipset Family v2.5.3.34 (2014-Feb-03) https://downloadcenter.intel.com/Detail_Desc.aspx?DwnldID=22824

2) I don't know what the SM Bus Controller is, but I bet an Intel driver would fix it. I had originally downloaded some other Intel drivers from their site -- chipset packages, etc. -- and installed them early on, so I never had to deal with "SM Bus Controller" appearing error'd in the Device Mgr.

(Word of warning: steer clear of the Intel Rapid Storage Tech driver. I've had problems with that, of different kinds, on 2 different machines. One with an Intel SSD, and one with a WD classic HD.)
