Vista USB Reliability PatchesPosted: October 6, 2007
Microsoft has published two Vista USB reliability patches. The first patch is public, KB941600, a general USB reliability patch like the ones we’ve seen before. The second patch is KB941858: You receive a Stop error message when you put a Windows Vista-based computer to sleep or into hibernation, or when you resume the computer from sleep or from hibernation: "0x0000009F DRIVER_POWER_STATE_FAILURE".
I’ve had the latter problem show up on my Vista machine; my HP iPaq 2495 frequently locks up when it’s in its cradle for a long time. As far as I can tell, this happens from the remote end when the ActiveSync client on the device locks up. This usually just locks up the iPaq, but sometimes it has bluescreened or even locked up the USB port on the Vista machine.
I can’t do a lot about the iPaq, since it is a previous-generation PDA, but I’d like it at least not to crash my Vista box. The patches are in already, and so far they’re quiet, a good sign.
To get KB941858, you’ll have to call Microsoft or request it on the web.
