Ubuntu, VirtualBox 2.2 and USB

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”

  1. Bookmark added without hesitation after finishing, and a look at sunnyflowercases confirmed I should bookmark the homepage too rather than just this page, the rare site that earns category level trust rather than just single article approval is the kind I want to rely on across many different topics over time.

  3. Right — have been messing about with this thing for maybe a few months now and it’s basically bookmarked at this point, so thought I’d chuck my thoughts in since a mate asked me the other day. Am in the UK, mainly bet football and racing, a fiver here and there, just so you know where I’m coming from.

    How I found it was actually a bit daft — I never could figure out what an each way payout actually came to with 1/5 odds a place. I’d just guess and moan when the payout landed. These days I type the odds in before every slip, even a simple single bet.

    Their single bet calculator is the bit I open most — you drop in stake and odds and you get returns instantly, fractions or decimals. It also handles the multiples — doubles and trebles maths, a lucky 15, yankees, honestly that’s where I always mess it up. Have a go yourself, it’s over at betting accumulator calculator and it’s free with no account nonsense.

    One thing that really made a difference were the more serious bits. They’ve got an implied probability calculator and it makes obvious the overround, and a kelly staking tool — I use half kelly as the full version is a quick route to a dead bankroll. Dutching calculator is handy too if I’m covering two or three runners.

    It’s not perfect mind. The interface looks very functional, let’s say — zero polish, looks like it was built by someone who cares more about maths than colours. Phone-wise it works though the bigger tables need a bit of scrolling. And no proper app, it’s a website and that’s it — fine by me but worth saying.

    Right, that’s me. Costs nowt, barely any ads, does what it says. If anyone still works out returns on a calculator app, give it a go — saved me a load of dumb bets I’d have regretted.

  4. Right — been on this thing for maybe four months now and I keep coming back, so thought I’d chuck my thoughts in since a lad on another thread asked me the other day. Am UK based, generally stick to footie and the horses, a fiver here and there, for context.

    The reason I started using it was honestly pretty stupid — I never could work out what an ew return actually was once you get five places instead of three. I’d just guess and moan when the payout landed. Now I stick my stake in before every slip, even a simple single bet.

    The single bet calculator tool is the one I open most — you put in stake and odds and it shows the return straight away, fractions or decimals. It also handles the multiples — trebles maths, lucky 15s, a yankee, which is where most people I know lose track. Have a go yourself, it’s here implied probability betting odds and it’s free with no account nonsense.

    One thing that actually made a difference is the geekier extras. They’ve got an odds-to-probability thing which shows you how much the bookie’s taking, plus a kelly staking tool — I use half kelly as the full version is terrifying. Dutching calculator is decent if I’m spreading across selections.

    It’s not perfect mind. The interface is a bit basic — zero polish, it’s clearly function over form. Phone-wise it’s usable though the acca grid make you pinch and zoom. Also there’s nothing on the app store, it’s a website and that’s it — doesn’t bother me just flagging it.

    So yeah. Doesn’t cost anything, barely any ads, does what it says. Anyone who even now works out returns on a calculator app, try it — saved me a load of “wait, that’s it?” moments.

  5. Right — have been messing about with this thing for something like a few months now and it’s stuck on my phone, so figured I’d write something up since someone asked me the other day. I’m UK based, mainly do football and horses, a fiver here and there, for context.

    What got me on it was genuinely embarrassing — I couldn’t ever work out what an ew return would be once you get five places instead of three. I used to just wing it and moan when the payout landed. Now stick my stake in first, every time, even the boring singles.

    The single bet calculator tool is the part I’m on daily — you put in the price and your stake and it spits out returns with no faffing, fractions or decimals. Same tool covers the fiddly ones — trebles returns, lucky 15s, yankees, honestly that’s where I’d always mess it up. If you fancy a poke about, it’s here yankee bet calculator and there’s no login wall, which I appreciated.

    What genuinely changed how I bet were the geekier bits. They’ve got an odds-to-probability converter which shows you what margin’s baked in, and there’s the kelly tool — I use half kelly since full stakes are a quick route to a dead bankroll. The dutch tool is handy too if I’m covering two or three runners.

    Not all sunshine though. The design is very functional, let’s say — not much polish, which honestly I don’t mind but some will. On mobile it works although the acca grid need a bit of scrolling. Also there’s no proper app, it’s a website and that’s it — slight shame but you asked.

    Anyway. Free, not plastered in adverts, works. If anyone still adds it up in their head, have a look — saved me a load of “wait, that’s it?” moments.
