Cool, not sure when you got the xml code from my first post, but I tidied it up a bit and edited it, can leave it the way it is if it hassle but I just removed the word "custom" from a lot of the variables.
Code:
<Query class="type:x-xmb/folder-pixmap" key="pkg_link_000" src="xmb://localhost/dev_usb000/package_link.xml#package_link"/>
<Query class="type:x-xmb/folder-pixmap" key="pkg_link_001" src="xmb://localhost/dev_usb001/package_link.xml#package_link"/>
<Query class="type:x-xmb/folder-pixmap" key="pkg_link_002" src="xmb://localhost/dev_usb002/package_link.xml#package_link"/>
<Query class="type:x-xmb/folder-pixmap" key="pkg_link_003" src="xmb://localhost/dev_usb003/package_link.xml#package_link"/>
<Query class="type:x-xmb/folder-pixmap" key="pkg_link_004" src="xmb://localhost/dev_usb004/package_link.xml#package_link"/>
<Query class="type:x-xmb/folder-pixmap" key="pkg_link_005" src="xmb://localhost/dev_usb005/package_link.xml#package_link"/>
<Query class="type:x-xmb/folder-pixmap" key="pkg_link_006" src="xmb://localhost/dev_usb006/package_link.xml#package_link"/>
<Query class="type:x-xmb/folder-pixmap" key="pkg_link_007" src="xmb://localhost/dev_usb007/package_link.xml#package_link"/>
