How well does Linux see USB network interfaces? More specificly, Fedora Core 9. My home server only has 1 nic and I've tried adding a PCI one but had issues (would not boot, may of been the nic). Now that it's live I rather not experiment with it in case it's the slot itself. Rather just put in a USB one while it's live and be done. Do these work good? I'm not expecting to go gigabit or anything 100mb ish will more then do.

Also this is more a vmware question, but if I bridge that nic to a virtual nic but don't use that nic within the OS, am I 100% secure that the system cannot be accessed through that particular nic? What I want to do is make it face the internet so I can have some VMs outside of my network, but on same server. Can this be done in a 100% secure way? (assuming I don't dual nic a VM and bridge to my main network)

What I'll probably do is use a hub, plug it into my dsl modem, plug my router into it, then plug that nic into it. I wont configure tcp ip on that nic, but just use it as a bridged network in vmware. So the server itself would not pull an IP right? Only VMs that are bridged to it?

As with anything it depends on the chipset, I haven't used any personally but I believe most should work fine. You probably shouldn't be putting your VM directly on the Internet anyway though, just give it a normal internal IP and forward the appropriate ports.

I'm using a USB wireless NIC (Ralink chipset) on one machine and Ubuntu sees and uses it just fine. Of course I made sure it was supported before I bought it.
