Hi,

I am trying to attach a Palm Z22 via USB to my fully virtualized Win XP.

Dom0-System: CentOS 5.3 x86_64 (Kernel 2.6.18.128.1.10.el5xen) XEN: 3.0.3-80.el5_3.2

XP: 32-Bit Professional

lsusb shows: USB Palm: Bus 002 Device 007: ID 0830:0061 Palm, Inc. Lifedrive / Treo 650/680 / Tunsten E2/T5/TX / Zire 21/31/72 / Z22

I found some hints that I have to put

usb = 1 and usbdevice = "host:0830:0061"

into my DomU-config.

When I start the DomU without the device switched on I get (qemu.log):

Warning: could not add USB device host:0830:0061 I/O request not ready: 0, ptr: 0, port: 0, data: 0, count: 0, size: 0 I/O request not ready: 0, ptr: 0, port: 0, data: 0, count: 0, size: 0 Triggered log-dirty buffer switch

When I start the DomU with the device switched on I don't get this error - but the usb-device does not appear in XP.

Questions: - why does the device not appear in XP? - is there a way to dynamically attach the usb-device (it is not present the whole time!)? - in the CentOS documentation abot xen (virtualization guide) I found an option "usbport" but I have found no exaple on how to use it - would this work instead?

http://www.centos.org/docs/5/html/5.2/Virtualization/chap-Virtualization -Configuration_files.html search for "usbport".

Kind regards

Nils
