Hi Folks, Interested in opinions on the best way to do this, and especially tales of success or failure so I don''t have to repeat someone else''s mistake. I want a DomU (winxp, hvm) to be able to access a few select USB devices. No other DomU or Dom0 will need to share them. And, I should point out that some of these are devices for which a Linux driver is either unavailable or unsuited for my purposes, so I really do need to run the Windows driver and have it "think" it''s talking direct to the USB. The sort of devices I am talking about include: A bluetooth adaptor, an ipod, an ipaq PDA, and an Actiontek "Internet Phone Wizard". Posibilities that I have considered: 1. Use USB passthrough, so DomU sees a virtualized device. I''ve tried this, using the qemu "usb_add device" command. No luck, so far. My DomU freezes when I try it, and I don''t know why. Also, googling around, I''ve yet to see any success story with this method, so I don''t think it works under Xen. 2. Use PCI passthrough, so DomU sees an entire PCI device. In this case, the PCI device would be a USB adaptor, and thus WinXP will see all devices and hubs under that adaptor. I have yet to try this method, wondering if anyone has done so with success? 3. Using USB-over-IP or some similar network tunneling. So far I''ve found one software-only product for this (http://www.usb-over-network.com/) and three hardware products (http://www.belkin.com/networkusbhub/ & http://www.home.agilent.com/agilent/facet.jspx?k=E5813A & http://www.digi.com/products/usb/anywhereusb.jsp). I can''t use the software-only product, because it requires a windows computer as host, with access to the native USB hardware. I have no such computer available. The hardware products seem promising, but the Agilent and Digi ones are very expensive, and the Belkin one is not yet available, as far as I can tell. Anyway, if any folks on this list have solved this problem in any of the above ways -- or others I haven''t thought of -- please share the details with me. Many thanks, Derek. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
