Ben, the symptoms of my problem are different than one described in the article you point out. As I said in a previous post (see below). Any hint you can provide me? Shall I try to apply update again but disconnect all USB devices first? Including getting
a wired keyboard and mouse?
Thanks in advance for all help
"Hello, I have also issue with KB2862330, however rather than BSOD I hit the problem that my USB system was not working anymore (including wireless keyboard and mouse). A System Restore fixed the problem.
If useful the system is an OEM one with an Intel board DZ77SL-50K
Also and with reference to previous posts, I have KB2533552 installed on my system.
Now I have hidden the update, and I am awaitng for a fix by Microsoft. Any news on this?"
