USB Power Issues

One of the main things that can cause connection issues is the USB port that you are using. Some USB ports may not provide enough power (or amperage) to drive a device correctly. One of the best remidies for this is to use a USB hub which uses it's own power adapter. These can be found for both in-home and for use in the car.

Here is some more info regarding the USB port which may be a cause of disconnects or software crashes.

The Problem:
Power Management and USB...
For some strange reason Microsoft and peripheral manufacturers just haven't seemed to be able to get it together with regards to hibernation and power management. The default condition for Windows XP is to leave on all power management even though many peripherals who know how to "sleep" on their own lose communication with Windows.

For example, if you own a multi-function printer that has a "power-saver" freature, you might be experiencing intermittent loss of USB communications with that printer, requiring you to reboot and/or reseat the USB cables before you can use your device.

Reasoning:
Here's what is happening. Windows sleeps the USBs because the computer is either in hibernation, standby, screensaver, or turned off. Now you turn on the computer or come out of one of the other conditions and windows wakes up the USB ports but can't see the printer because the printer is either off or in power save mode. At this point WindowsXP shuts down communications with that device and when you attempt to print, you get an error that Windows can't communicate. You're told to reseat the cables and several other things that don't work.

The printer driver tried to "ping" the device and that "ping" wasn't returned.

Possible Fix: Now let's fix this problem.
1.Click on "Start" and then right-click on "My Computer."
2.Click on "Properties" and then on the "Hardware" tab.
3.Half-way down on the right, click on "Device Manager."
4.Click the "plus" sign in front of "Universal Serial Bus Controllers."
5.Double-Click on the first "USB Root Hub" (not USB 2.0 Root Hub).
6.Click on the "Power Management" tab.
7.Uncheck the box that says "Allow the computer to turn off this device to save power."
8.Click "OK" and repeat for all other "USB Root Hubs."
9.Finally, close all and go back to the desktop.

Now, the next step is optional but advisable, in my opinion.
1.Right-click on the desktop background
2.Click on "Properties."
3.Click "Screen Saver" tab and then "Power" button
4.I like the following settings for a desktop computer:
•Monitor - 15 minutes
•Hard Disk - 20 minutes
•Standby - Never
•Hibernation - Never

5. Then click on the "Hibernate" tab and uncheck "Enable Hibernation."
6. Click "OK" twice and go back to the desktop.

Last, I would suggest that if you've been having this problem, you should uninstall the existing printer driver and download the lastest driver off the manufacturers website. That lastest driver or driver patch probably does a better job of coexisting with Windows XP hibernation modes.

If you still have communication problems related to hibernation and power saver modes on your device, always turn the device on prior to starting your computer. XP will have to notice it then. Or, just leave the printer on all the time and let it "power-save" rather than turning it physically off.

The Problem:
If you connect a Universal Serial Bus (USB) input device while another USB device is saturating the bus, you might receive this message or one similar to this message:

STOP: 0x0000007E (0xC0000005, address, address, address)

usbhub.sys

Note that the second, third, and fourth parameters in the error message may vary.

Machine may also reboot on connection of USB cable from a new device.

This problem may occur if USB bandwidth consumption exceeds 100 percent when you connect the new USB device.

Reasoning:
Exceeding the maximum USB bandwidth during the enumeration of a new device exposes a lack of protection that is related to device removal.

Possible Fix:
To work around this issue, use any of the following methods:

1. Connect your USB device before you start streaming USB video, audio or other saturating activities. Disable streaming USB devices like Video cams and such prior to installation. Close or disable such items in the Systray.

2. If your computer has multiple USB host controllers, connect the device to a USB port that is connected to a host controller other than the host controller to which the USB video or audio device is connected. Most machines have two host controllers, hopefully.

Check to make sure that root hub draws over 50 mil amps and under 500. (device manager / USB root hub / power) If not within spec, system might be rebooted to reset hubs.

Future considerations:
This above situation refers to saturation of a particular controller and not the saturation of the PCI bus. PCI bus saturation could cause the same or similar problem, I would expect. Imput would be appreciated.

How to solve problems with specific USB UHC chipset

This section describes many, but not all, USB chipsets commonly installed in computers. If you do not find information here about the USB UHC chipset installed in the computer, contact the manufacturer of the computer or the motherboard for further help.

Intel 82371AB, EB, MB, SB, and AB/EB
Intel 82371AB, EB, MB, SB, and AB/EB were some of the first USB host controllers. Intel has identified several problems with these controllers. The most significant problem is that Windows does not always identify a device when it is connected to the system. Another problem is that the device and computer may stop communicating when the system comes out of screen saver, suspend, or hibernation modes. The symptoms can occur randomly, so it may be difficult to identify the cause. Intel greatly improved the 82371 AB/EB controller, which was the last of the series. There are fewer problems with the 82371AB/EB chipset, but problems still may occur. Intel is not planning any long-term fixes to any of these issues. You may want to try the following solutions.

NEC universal host controllers
This chipset is normally found in Toshiba and some IBM laptops. Microsoft has created a patch for computers using this chipset. The information is contained in their Knowledge Base Document Q244594.

Problems with power
Some USB chipsets may cause problems related to power. USB devices obtain the power to drive USB communication from the computer through the USB cable. The computer can detect a device at power levels as low as 100mA, but 500mA may be required to maintain high-speed communication with a full power USB device. This problem exists on some computers, USB hubs, and USB-connected peripherals that act as hubs. Symptoms that may indicate power-related problems are listed below:
• Plug and Play does not detect the all-in-one during installation.
•The all-in-one functions only partially or is frequently disconnected.
•The all-in-one will only work if other devices are disconnected.
•The computer restarts when you try to use the all-in-one.

The known problems that have to do with power are listed below, but other devices may also have these problem. In general, any Plug and Play or communication problem that is not caused by a USB chipset or cable may be caused by a problem with power. Complete the following steps to check the power properties of the USB root hub:
• Right-click My Computer, and then click Properties.
•Select Device Manager (in Windows 2000, click the Hardware tab, and then click Device Manager).
•Locate and click Universal Serial Bus Controller entry.
•Double-click USB Root Hub to open the USB Root Hub Properties.
•Click the Power tab, and then click Power Properties. Windows displays the amount of power available and the amount of power used. When the computer and peripherals are idle, the power usage will be lower than when the computer is active. Note that Windows may or may not report the information correctly.

Certain USB keyboards do not provide enough power to drive a full-power USB device (such as a printer, scanner, or all-in-one). You should not use this type of USB keyboard to connect other USB devices. These keyboards have two integrated USB ports that only supply about 100 milliamps of power. Disconnect the all-in-one from these ports and connect it directly into the USB port on the computer. You may also purchase and install a powered USB hub, and connect the all-in-one through the powered hub.
