#2407 obsolete Driver issue with CD/DVD passthrough with Windows host and windows guest Kevin Shea
Description

I have a windows XP host and windows XP guest and have created a VM with a passthrough DVD writer.

When booting the VM I get the following sequence of events: 1) first boot - VBOX CDROM detected OK, everything works as expected including burning 2) second boot (after normal shutdown) - driver conflict on VBOX CDROM detected.

After uninstalling the driver and rebooting I end up back at stage 1 again, and so on. The same VM works perfectly and repeatedly when the host is linux (Ubuntu 8.04).

The specfic windows error is: "Windows cannot load the device driver for this hardware because there is a duplicate device already running in the system. (Code 42)". (nothing useful on MSDN - they helpfully suggest rebooting the PC...)

Happy for this to be a minor issue - my VM will be used primarily with the Ubuntu host and rarely used for burning disks with.

#2408 fixed Problems with USB on Windows Host (XP and Vista) xfernandez
Description

I started with only 1 Gigabyte of RAM on the host system (Windows Vista). With this amount of RAM:

· VirtualBox can start the VM · It seems impossible to control USB devices (in general, not just the IO card) · The system becomes very slow and is likely to hang after awhile

I added 1 Gigabyte of RAM to the system and noticed improvements: · The system does not become slow nor hang. · I was able to access a pen drive and a standard Bluetooth dongle from the VM with no problems. · I was able to access the IO card with problems (described below).

It's necessary to have 2 Giga of Ram in the Host?

In the probes I use an IOCard that it's connected via USB. This IOCard has 3 bluetooth devices. This 3 devices are detected on USB filter creation. And I only connect the IOCard when the VM is running. In general the VM detects the bluetooth USB devices (My guest is a Linux and I use the hciconfig command).

But In some cases, it appears problems: · Sometimes appears the error: "USB device is busy with a previous request, please try again" Result Code: E_INVALIDARG (0x80070057) · Simetimes VM detects 3 devices, other times 2 devices, 1 device, 0... I can't understand the behavior.

If you need more information, no doubt of ask me.

#2409 duplicate Problems closing de VM and the VBoxSVC.exe process xfernandez
Description

Some times, when I close the VM, this doesn't close well. And the VM and the virtualBox management windows crash. I can close the two windows using the task administrator but the VBoxSVC.exe process is in memory with the RAM that VM needs (>256 Mbytes). I can't close the process using the task administrator and I only can restart the computer.
