Hi again, I'm now one step closer to my goal! I can passthrough my radeon video 
card, but I can't get it working in Windows. I had to switch back to xm, xl 
seems to be very buggy. After I switched back to xm my Windows HVM had access 
to the internet. The good news is that I can use the echo 0000:05:00.0 > 
/sys/bus/pci/drivers/pciback/bind commands now, I think the reason why I 
couldn't before is because I didn't know I had to blacklist the Radeon driver. 
For some reason I can't pass my PCI USB card now though, it is giving me the 
same error it was giving before for my video card. In the Windows device 
manager my PCI devices are listed as Multimedia Audio Controller and PCI 
device. Windows doesn't seem to know that one of the the PCI devices is a video 
card. I downloaded and installed the driver for my video card and restarted 
Windows. The problem now is that after restarting it boots into a blue screen 
that tells me something is misconfigured, and that Windows is shutting down to 
avoid damage to my hardware. I can boot in safe mode still though. I am not 
sure what to do to try to fix this. My video card doesn't have FLReset+, but I 
read that the AMD video cards work with Xen. Thank you very much for helping me.
