virtualbox.org

I got VBox installed on my Acer Laptop running Linux Mint 6 with XP as the Guest OS (I'm a Linux newbie & first attempt at Virtual Software)

Have read the Manual & tried hard to understand what I am supposed to do to get my USB stick recognized/seen in XP Guest (is working under Host)

Have installed Guest Additions & added USB Filter (blank) but I can't see my USB flash drive and get the following Error Message:

Failed to access the USB Subsystem
could not load the Host Proxy Service (VERR_FILE_NOT_FOUND)

Result Code: NS_ERROR_FAILURE (0x00004005)
Component: Host
Interface: IHost
Callee: IMachine

Any help appreciated, any code input, step by step please

Thanks & a Happy New Year

Look into the FAQ, there you will find how to setup USBFS for Ubuntu.

Thanks stefan, found the FAQ section on your suggestion and as a newbie this was a bit scary, but in a Terminal I entered Sudo gedit /ect/init.d/mountdevubfs.sh. (brought up mountdevudfs.sh page to edit)
Then added suggested code from FAQ:
mkdir -p /dev/bus/usb/.usbfs
domount usbfs "" /dev/bus/usb/.usbfs usbfs -obusmode=0700,devmode=0600,listmode=0644
ln -s .usbfs/devices /dev/bus/usb/devices
mount --rbind /dev/bus/usb /proc/bus/usb

Didn’t solve problem, so then tried > sudo gedit /etc/fstab & inserted:
none /proc/bus/usb usbfs auto,busgid=XXX,busmode=0775,devgid=XXX,devmode=0664 0 0
(replacing XXX with my vboxusers number)

Problem remains, no USB visible within XP Guest

So where to now? Any help much appreciated & Happy New Year

Linux Mint 6 is based on Ubuntu 8.10, so only the /etc/fstab entry should be enough. Be sure that you have the variables set properly for your own enviroment. That means that the devgid=# is the group ID of the VBoxUsers group.

Thought I may have found the problem, rechecking everything I think I found a typo in the FAQ section ie mountdevsubfs instead of mountdevusbfs

Anyway entered the code again with corrected spelling & removed code I inserted previously with incorrect spelling (I was so careful to type everything exactly as it was in the FAQ)

Unfortunately still no visible USB flash drive under XP Guest OS, at least the additional code doesn't appear to have upset seeing the USB under the Host OS

What about an error? Do you still get the USB Proxy error or not?

Thanks for the input Sasquatch

I am stumbling through this, but I did make sure I used the correct devgid number for the vboxuser group

No, the error message no longer appears, but still no USB flash drive is visible under XP Guest

Thanks for the suggestions guys, hepled me get there in the end

Found this tiny symbol/icon for USB's below the Win XP task bar and when I right clicked on it I could see my USB Flash Drive, clicking on it activated it and XP picked it up & installled it as new hardware

So this icon & the sudo gedit fstab with this code input:
none /proc/bus/usb usbfs auto,busgid=XXX,busmode=0775,devgid=XXX,devmode=0664 0 0

seems to have done the trick, took me a while, but with this Forums's help I was able to get my USB working under XP Guest OS

Thanks
