What could I try now?

Well,it could happen sometimes,it actually doesn't require any specific drivers for your PC/Laptop so don't worry.
Try changing usb-port on your computer,even then it doesn't detect do one thing,let your device boot while plugged into your computer, Yes you'll not able to get wifi-connectivity first but your device will boot normally,finish the setup process and first thing you'll notice is connect: USB CONNECTED. "Turn on USB Storage"
Later on you may able to go back into fastboot and flash boot.img via "fastboot flash boot boot.img" and everything will become normal as it should be.you will able to get wifi connectivity as well.
