Kali Linux External Wifi Not Working?

I have 2 external wifi cards. Alfa awus036h and TP-link WN722N. I'm using Kali 1.1.0 on Virtual Box.

Here's what I have tried my Wi-Fi cards with only to end up unsuccessful.

1) Tried with Network settings (on Virtual Box) set to 'NAT' and also with 'Bridged Network'. Checked USB 2.0 and added my wifi card.

2) Tried both Virtual Box and also Vmware.

3) Tried with both Kali 1.1.0 and Kali 2.0.

4) Tried on both Windows 8.1 and Windows 10.

5) Tried on various versions of Virtual box including the latest 5.0.

6) Tried almost all the fixes available online.

But unfortunately none of those work. Last time it worked was with my Windows 8.1 (I can't remember Kali version but 2.0 wasn't released back then). I then decided to upgrade to Windows 10 and the problem began from there. Kali couldn't list up the available networks. I then reverted back to Win 8.1 (formatted the previous windows and did a fresh install) but still the problem persists. The "Cable Connected" option works just fine. But there are loads of tools that require you to have a wireless interface so I'm missing out a lot.

Currently, I'm using Kali 1.1.0 on a Disc which is working almost fine but I want it to detect my wireless card in Virtual box because I can't go through the hard work of switching between Windows and Linux every time I need to perform a pen test.

Helpful comments will be highly appreciated.
