Hello all, I have recently been having trouble getting my USB wireless nic (TP-Link WN722N with ath9k chipset) to work with VMs on my desktop computer (Win 8.1 x64, MSI motherboard Intel H87). I believe it worked a few months ago, but I'm not sure what changed since then. The weird thing is, it has always worked just fine on my laptop (plug it in, select it in devices, and it immediately shows up in the guest's ifconfig). I have tried to make sure they are both on the same drivers, but there are so many different ones and none seem to work. It's not the VM, because I'm using the exact same vdi on both computers and it doesn't change anything. It shows up under lsusb (in the guest) with the correct output, but syslog reveals some errors downloading the firmware.

Virtualbox 4.3.12 on both computers, same with guest additions. Neither computer is using the extension pack, which doesn't seem to be needed. I'm only using USB 2.0 ports, I've tried multiple ports too. Anybody have any ideas how I can get it to work on my desktop?
