All usb ports not working - Error code 19
Hi my laptop runs on XP pro, yesterday all my USB ports have suddenly stopped working.
When I go to the device manager and expand the Universal Serial Bus Controllers, all have a yellow exclamation mark beside them.
When I check their status this is the message: Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged.
I was not in the registry prior to this, so I don't know how it got damaged.
I have followed instructions from here http://support.microsoft.com/kb/310123
I tried this: Click Uninstall, and then click Scan for hardware changes to load a usable driver – no effect.
I tried this: Restart the computer in Safe Mode, and then select Last Known Good Configuration,which rolls back to the most recent successful registry configuration – didn't fix the problem.
Microsoft says that as a last resort, you can edit the registry directly – but I not sure where and what to edit in the registry plus the link provided doesn't go anywhere.
If anyone can tell me what keys to edit in the registry I would very appreciative.
I will do anything to avoid reinstall windows from scratch.
I unfortuately didn't have system restore going so I cannot use that.
There is a somewhat similar question in this forum here http://social.answers.microsoft.com/Forums/en-US/vistahardware/thread/e60c03dc-629e-43e7-b476-3863a14ea033
but the answer provided SpiritX MS MVP does not include editing the registry.
Thank you in advance.

How to Avoid Downloading Malware
Where are you getting the download?
There are malicious people who download valid copies of a popular download, modify the file with malicious software, and then upload the file with the same name. Make sure you are downloading from the developer's web page or a reputable company.
Cancel or deny any automatic download
Some sites may automatically try start a download or give the appearance that something needs to be installed or updated before the site or video can be seen. Never accept or install anything from any site unless you know what is downloading.
Avoid advertisements on download pages
To help make money and pay for the bandwidth costs of supplying free the software, the final download page may have ads. Watch out for anything that looks like advertisements on the download page. Many advertisers try to trick viewers into clicking an ad with phrases like "Download Now", "Start Download", or "Continue" and that ad may open a separate download.
