OK, here is an update. Just to summarize: In order to be able to use USB over IP for Linux clients/VMs, it looks like the only solution available right now is the free software based USBserver&Client from incentivespro.com. All other suggested hardware based USB servers like from digi.com and Silex don't support Linux. True, as Ken said, I could use cups for printing, and mount USB hdd over samba or nfs, but I am not convinced that a usb card reader (aka programmer) can be dealth with the same way. I also have my doubts about using a dvd burner from a VM that is installed on dom0, though nobody has so far told me that indeed this can be solved. So I am still in the dark ;-). With focus on having a true USB server for Linux, I have taken a few steps and have come this far: - I installed XenServer 5.6.0 - downloaded the USB server software from incentivespro.com - I ran the installer.sh and got an error that Make was not installed. - I edited the repository files on the Xenserver, and changed enabled=0 to 1 - ran yum make install, and then Make worked as it should - I ran the USB server installer and came across a new problem, that Incentivespro knew was bound to happen. On there web site they say: -------------------------------------------- If you've got an error during driver compilation, while installing USB Server and USB Client for Linux, please follow these instructions to compile a driver manually. Some USB Server & USB Client components are operating in kernel mode. So, you need to compile the special driver to install our software product. Source code of this driver is in usbserver.tar.gz/usb-server/modules/src/tusbd/ directory To compile USB Server & USB Client for Linux please use FULL kernel source codes! If you use header files only, please check the presence of the: - ~linux-source-directory/drivers/usb/core/hcd.h - ~linux-source-directory/drivers/usb/core/hub.h If there are no such files, please copy them from source code package of your kernel version. ----------------------------------------------- There are no files in the /usr/src directory, so I must assume that the linux headers are not default installed on XenServer. Googling learned me that somebody had the same problem before: (from http://purl.rikers.org/%23debian/20091202.html.gz) you need to install linux-headers-$(uname -r) then tell the installer the source dir is /usr/src/linux-headers-$(uname -r) instead of /usr/src/linux How to Build a Kernel Module for XenServer is explained here: http://support.citrix.com/article/CTX116387 But to be honnest, that is far out of my lead. I never done this before. On the other side, I have nothing to loose, so maybe I will give it a try. But my question to the real experts is: If this free software USB server is the answer to our prayers, then why isn't it a part of the XenServer. It should be supported one way or another, don't you agree? But untill this prayer is heard, I would love to get some help, so we can test this piece of software, and tell the XenServer community that this realy works. Looking forward to hear from anybody that can help.

Now I have no make errors. Up to the next problem. Something not Xenserver related. I'll figure it out, and let you know how it goes.
