There is a very nice script for Windows dealing with attaching XenServer USB disk to a guest. It can be found\u00a0here<\/a>.<\/p>\n

This script has several problems, as I see it. The first \u2013 this is a Windows batch script, which is a very limited language, and it can handle only a single VDI disk in the SR group called \u201cRemovable Storage\u201d.<\/p>\n

As I am a *nix guy, and can hardly handle Windows batch scripts, I have rewritten this script to run from Linux CLI (focused on running from the XenServer Domain0), and allowed it to handle multiple USB disks. My assumption is that running this script will map\/unmap *all* local USB disks to the VM.<\/p>\n

Following downloading this script, you should make sure it is executable, and run it with the arguments \u201cattach\u201d or \u201cdetach\u201d, per your needs.<\/p>\n

And here it is:<\/p>\n
