#7158 fixed microsoft natural usb keyboard crashes usb support in VB - fixed as of 2010/11/18 Rogier
Description

I discovered the following problem.

First i describe my hardware setup. I am using a Microsoft Natural USB keyboard on my linux host. I do not activate this USB keyboard in VB because the keyboard function works.

The Error situation. When i want to use a USB-stick in my windows XP guest OS, i activate the the USB stick with a right-click on the usb icon and select the USB stick. This all works without the USB keyboard attached. When i attach the USB keyboard and want to use the USB stick, i get only a list with: Microsoft, Unknown device, Unknown device, Unknown device. When I right-click the USB icon a second time, nothing happens, no list, nothing. VB still works it does not hang.

I attach the logfile which is the result of the plugging in the keyboard and usb stick.

What i did is the following.

  • Shutdown the running Windows Xp VM
  • Quit in Linux host the VB
  • Attach the USB keyboard
  • Start VB
  • Start Windows Xp VM
  • Entered in windows xp VM my login name and password
  • Waiting.... see Time stamp 00:01:16.360
  • Attached the USB Stick
  • Right-click the usb icon and select the USB Stick
  • Error window Appeard:

#13052 obsolete metrics setup does not reset prior setup Senthil Nathan
Description

Step 1 - do a metric setup as below

VBoxManage metrics setup --period 1 --samples 10 SomeVM Guest/CPU/Load/Idle*

Step 2 - query to confirm it works

VBoxManage metrics query SomeVM Guest/CPU/Load/Idle*

Step 3 - do a modified setup as below

VBoxManage metrics setup --period 1 --samples 5 SomeVM Guest/CPU/Load/Idle*

Step 4 - query to confirm it does NOT work

VBoxManage metrics query SomeVM Guest/CPU/Load/Idle*

Step 5 - do a different setup

VBoxManage metrics setup --period 1 --samples 5 SomeVM Guest/*

Step 6 - query to confirm it does work

VBoxManage metrics query SomeVM Guest/CPU/Load/Idle*

Question is, why does it not work in Step 4 - as if Step 3 did not happen, where the sample size was changed from 10 to 5? Is this a bug or is this default behavior? And then it does work when the metric is setup (reset) at the higher level.
