No chance. Any provider that allows you to connect up a USB device to their live shared servers is a complete retard.
USB passthrough works with VMware, I've done it, but that's not really the point
Server management can mean alot of things. With some providers it's more of an insurance policy should you break your own server, in that they will come along and fix it for you. They might include patches and so forth but that stuff is automated anyway so work it out? Other providers take it a bit more seriously and will manage the entire process for you, whether thats adding an FTP account, making changes to your web server and so forth.
