VMware Server v1.05 - USB 2.0 - Blue Screen of Death Workaround

skill level: intermediate
I operate Ubuntu Desktop v7.10 (Gutsy gibbon)
I installed VMware Server v1.05

• VMware Server is free
• VMware Server does not support USB 2.0
• note: VMware Workstation v6 costs money, but does support USB 2.0

I installed Windows XP into my VMware Server Session.
When I plug in my USB 2.0 device and install the driver the XP would get the Blue Screen of Death (BSOD)

There are a few solutions that are effective:

• Solution 1 - Easiest:
• Plug a USB 1.1 hub into your USB 2.0 port, then plug your USB 2.0 device into the USB 1.1 HUB.
• Solution 2 - Not convenient or a likely modern possibility:
• Check your VMware BIOS (and possibly even your Host PC's BIOS) and see if the BIOS allows you to force USB v1.1.
• Solution 3 - Most effective and assumes a Linux Host:
  
• Open a ternimal session and type: rmmod ehci_hcd
• This command unloads the USB 2.0 module and Linux favors the USB 1.1 module.
• You can do this on the fly, while VMware is running, before you plug your device into the port.
• You can also relaod ehci_hcd on the fly when you are done: modprobe ehci_hcd
• If you reboot Linux it will automatically default back to loading ehci_hcd

Laptop Power Management, Ubuntu v7.10 (Gutsy Gibbon)

skill level: intermediate
Your laptop probably scales processor speed just fine.
I travel many hours by plane and much prefer to force most efficient use of my laptop's battery life. This method is very easy to switch between On Demand / Power Save settings

• Add the CPU Frequency Scaling Monitor to your panel
• Right click on the panel and choose add to panel then drag the icon for the monitor over to the panel
• If it will not let you add the monitor your computer does not support CPU frequency scaling
• Now you can see what’s going on with your processor, next we’ll change things so you can control it
• Some dual core systems allow independent control of the frequency scaling for each core
• Add another copy of the scaling monitor for each core and in the preferences change each so it monitors a different core
• Now open a terminal window:
• $ sudo dpkg-reconfigure gnome-applets
• follow the dialog of the command and "Yes" for SUID control
• Now you should be able to left click on the CPU Frequency Scaling Monitor and choose what speed/setting you want your processor to run under.

After a reboot it will default to On Demand. You will have to manually set these to Power Save each time. NEVER set your processor speed to MAX! Only choose On Demand or Power Save.
