Troubleshooting
To prevent Windows from ???managing??? power to your USB controller or
devices, follow these steps:
1. Open Device Manager (devmgmt.msc).
2. Expand the Universal Serial Bus controllers branch.
3. Double-click the USB Root Hub device, and choose the Power Management
tab.
4. Turn off the Allow the computer to turn off this device to save power
option, and click OK when you??™re done.
See ???Start Windows Instantly (Almost),??? in Chapter 5, for other power management
issues.
Fix Printer Problems
A lot of people are having trouble printing in Vista, but nearly all their problems
can be narrowed down to two areas: cables and drivers.
If you??™re experiencing poor printing speed, errors, or garbled output, eliminate
any USB hubs you might be using, and plug your printer directly into
your PC. If you??™re out of USB ports, consider connecting your printer
directly to your network; see ???Use a Print Server Without Software??? in
Chapter 8.
As for drivers, the problem that plagues many printers is that the drivers
provided by the printer manufacturer try to do too much, and as a result,
bog down your system (and your printing) with extraneous programs and
dialog boxes. If Windows Vista supports your printer out of the box, consider
abandoning the fancy drivers that came with your printer in favor of
the plain-vanilla ones Microsoft provides.
Otherwise, many common printer problems involve incorrect paper: use
laser paper for laser printers, and inkjet paper for inkjet printers??”avoid the
???multipurpose??? junk.
