    I just tried Parallels Workstation on Linux with Windows XP as guest OS. Everything is fine, but I can't find the USB-Controller. I did everything I was told by help-page "Problem with Connecting USB Devices in Linux Primary OS". But the line "USB-Controller" not even appears in the list of ressources (see Attachment).
    I don't know, what's wrong, but I need USB to use the Software. Can anybody help me.

    My Primary Sytem is SuSe Linux 10.2 with kernel 2.6.18. USB works fine there.
    Guest OS is Windows XP home.

    The line in question in /etc/fstab reads:
    I'm definitely member of this group.

    Usb

    I will try,

    Put this into the *.pvs file at the end.

    [Usb]
    USB enabled=1
    USB=1
    USB autoconnect=1

    Then try running parallels from command line as root.

    I usually do this with sudo parallels.

    Give that a try and let me know.

    Thanks

    Thank you very much, rfulcher! Now I have the usb-controller in the list of ressources. As long as I don't start guest OS, everything seems perfect. That may be the first step.

    But still: Windows as guest OS doesn't recognize any usb-device, neither printer nor stick.

    Any other ideas anybody?

    usb

    I know this seems a little weird. I can get it to see sticks and regular external drives fine by starting parallels as root. Then waiting for it to fully start, some times I would have to start and stop the guest os several times and then it would start to work pretty consistent now. I only have issues with Ipod and Palm devices. Take a look under the device manager and see if you are getting a usb icon (the yellow one for conflicts) and then try adding it manually. Sudo is really the key for me.

    Thanks

    Thank you so much. But the problem must be different with me. I can be root or normal user: it doesn't matter - usb doesn't work with guest windows.
    In the device manager everything is fine. No yello warning sign. USB-contorller ist present.

    recompile kernel

    I had the same problem, did a lot of research and posted here.

    I found that you need to make sure that the kernel is compiled to support usbfs (which I know SUSE 10.2 is NOT (I'm not sure about other distributions)).

    You can check to see if usbfs is supported by your kernel by checking if there is a usb directory in /proc/bus.

    If it is not present you can compile the kernel with CONFIG_USB_DEVICEFS enabled (there are decent instructions to recompile on SUSE at http://www.howtoforge.com/kernel_compilation_suse).

    Once the kernel is installed and the machine rebooted you can check /proc/bus for a usb directory.

    Good luck.

    Very good to get still an answer. I nearly got used to work without usb. As I work with suse 10.2 I really don't have support for usbfs in the kernel. As soon as I've got time, I will try your way. Thanks.

    likewise 10.2

    I likewise am using SUSE 10.2 and once I complied the kernel with USBFS support and changed noauto to auto in my /ets/fstab, I had USB support.
