Absolutely not. I can think of at least two ways I can (repeatedly) get a BSOD on my Dell Latitude E6430 with Win 7. Both involve USB (on the 3.0 ports). The sad thing is that my 2005ish Dell Latitude was quite bulletproof. I think Dell (like others) has gone lowest bidder for hardware and it shows in their current gen USB controllers...

To be fair, I'm talking Developer type USB devices like wireless packet capturing devices, wifi saturation simulators, etc. All work fine if I use the single USB 2.0 port, but if plugged into 3.0, the usually BSOD as soon as they are initialized. So much for retro compatibility...
