Need help getting Virtual Box to recognize USB, local hard drive and RS232 (Com port)

[p_squared]

Any luck getting your serial port working? I am getting the same error as you.

Nope...... -_-..... at least USB works now.

I still can't shared folder stuff to work either.

Wonder how long till they develop a way to directly access the graphics card?

New to ubuntu, the first Linux I would like to use (and drop Windows xx as much as possible). I like UBUNTU.

VirtualBox context :
Host : Hardy 8.04
Guest : XP SP2

PB is, can't open com ports in VirtualBox :
===========================================

When I activate com port support the virtual machine doesn't start, I get the msg : Can't start virtual machine xxx

Failed to open host device '/dev/ttys0'.
VBox status code: -250 (VERR_DEV_IO_ERROR).

Result code : 0x80004005
Component : Console
Interface : IConsole {d5a1cbda-f5d7-4824-9afe-d640c94c7dcf}

VirtualBox config options :
Interfaces séries :
Interface série 0 COM1, Périphérique hôte (/dev/ttys0)

Host serial port info :
=======================
The command : ls -l /dev/ttyS0
returns : crw-rw---- 1 root dialout 4, 64 2008-08-15 00:44 /dev/ttyS0

I can get input data in GTKterm from /dev/ttys0

Can somebody help ?

Ok, I've got some semi-good news for you.
I've successfully gotten virtualbox working with my serial port (and usb devices) with xp sp2
The bad news is that it's late, and I can't describe how to do it without messing around for an hour on my other computer. But it's not too hard to do, and you may figure out how to do it by the time I re-investigate it for myself. (I'll post here if I find out how I did it).

I initially got it working fine by following some ubuntu virtualbox tutorials (do a google search to find them).

If someone else knows more, please post here.

In response to Mr. Unknowns' comment "nothing happens when I select "Install Guest Additions"", I noticed that unless you run VirtualBox as superuser, you can't install Guest Additions. To run Vbox as superuser:

sudo VirtualBox &

Here, the word VirtualBox is case-sensitive. The "&" symbol simply puts the process in the brackground, freeing your terminal window so you can still use it.

I had the same problem - but the solution was very easy:

Did you really write /dev/ttyS0 ??

The letter "S" must be written as capital-letter!
