Ubuntu, VirtualBox 2.2 and USB

Published by Matheus (X-warrior) Bratfisch on April 25, 2009

Hello,

Now, with this new version of ubuntu, i will post alot about it while I’m trying configurations. I don’t want to teach how to install VirtualBox 2.2, because it’s a package .deb and is so easy to install it (Download Sun VirtualBox). In this post I want to remember that we should select the option “Enable IO APIC” in “Settings – General – Advanced”. (My version of WinXp doesn’t work without it). So if you system is not booting, verify this option. Now let’s go to enable USB in your Virtual machine.

You have to install “Guest Additions”, use the menu “Devices – Install Guest Additions”. (Don’t forget to mount it on your cd in virtualbox)

After you install it go to console:

$ grep vbox /etc/group
The result is something similar to this: vboxusers:x:gid:user

(If your user is not there, add it “System – Administration – Users and groups”)

Edit the file “mountkernfs.sh”:
$ sudo pico /etc/init.d/mountkernfs.sh

Go to the end of do_start(), and before the } add this line:
domount usbfs “” /proc/bus/usb usbdevfs -onoexec,nosuid,nodev,devgid=GID,devmode=644

(Replace the GID with your GID)

Save the file, reboot the computer and use your usb in your virtualmachine.

The site that make me try this way is http://www.davidgrant.ca/virtualbox_usb_windows_xp_guest_ubuntu_hardy. This website don’t says it works on Ubuntu 9.04 (Jaunty), so i tried and it worked.

I hope this is useful,
Matheus

PS: You have to select the device you want to use in virtual machine in “Device – USB DEVICES”

    OK — have been messing about with this thing for maybe four months now and I keep coming back, so figured I’d write something up since someone asked me last week. Am in the UK, mostly bet football and racing, a fiver here and there, so take it how you like.

    What got me on it was actually a bit daft — I could never figure out what an each way return would be when the place terms changed. I’d just wing it and get a shock. Now punch the numbers in before I place anything, even a straight one-selection punt.

    The single bet calculator tool is the one I use most — type in the price and your stake and it shows returns with no faffing, fractional or decimal, doesn’t matter. It also handles the multiples — doubles and trebles returns, lucky 15 and lucky 63, a yankee, honestly that’s where most people I know got it wrong. Have a go yourself, it lives at football acca calculator and there’s no login wall, which I appreciated.

    What actually changed how I bet was the nerdier tools. There’s an odds-to-probability converter which shows you how much the bookie’s taking, and there’s the kelly staking calculator — I run quarter kelly since full stakes are far too aggressive. Dutching calculator gets used a fair bit if I’m covering two or three runners.

    Couple of gripes. Its design feels very functional, let’s say — no flash, which honestly I don’t mind but some will. On mobile it’s fine though the acca grid need a bit of scrolling. And nothing on the app store, it’s a website and that’s it — doesn’t bother me but you asked.

    So yeah. Doesn’t cost anything, not plastered in adverts, works. Anyone who even now works out returns on a calculator app, have a look — saved me plenty of dumb bets I’d have regretted.

    Generally I am cautious about recommending sites on first encounter but this one warrants the exception, and a look at vixarobonding reinforced the exception making, the rare site that justifies breaking my normal cautious approach is the rare site worth flagging early and this one has prompted exactly that early flagging response from me.
