Xen users - Jan 2011 - xm usb-add syntax

Hi all,

Do any of you know what the syntax would be is I wanted to add the  
first device listed using lsusb on my dom0 to my domU?

lsusb;

Bus 002 Device 004: ID 064f:0bd8 Some-Systems AB ABC/DE

xm usb-add;

Usage: xm usb-add <domain> <[host:bus.addr]
[host:vendor_id:product_id]>

Unsure what combo works, other then what doesn''t work.

- Brian

what is the output of "xm usb-list-assignable-devices"

maybe this is what you need:

o first you have to create a host bus adapter like:
  xm usb-hc-create domU 2 2

o and than you can attach an usb-device like:
  xm usb-attach domU 0 1  2-4

where domU is the name of your guest.

You can add this to the domU config file like:

vusb=[ ''usbver=2, num-ports=2, port_1=2-4'', ]

Hi Dieter and thanks.

I found some docs explaining that on my guest VM, I should run  
"modprobe xen-hcd" which returns;

FATAL: Module xen_hcd not found.

The kernel on this PVM is 2.6.18-53.

At any rate, after I run the command;

xm usb-attach domU 0 1  2-4

I get this;

Unexpected error: xen.util.vusb_util.UsbDeviceParseError

Please report to xen-devel@lists.xensource.com

Should I post this to xen-devel?

can you confirm steps how to add USB flash drive to Windows 2008 DomU ?

shall I mount it in dom0 before doing xm usb-add ?

when I do:

"xm usb-add windows2008  host:xxxxx.aaaaa"

it shows in Windows devices with* "!"* saying it works with slow speed
1.1
(what is normal for usb-add command) but I can''t see any new drives in
the
system. what am I missing?

please advice,

Alex
