How to solve problem with USB devices not responding on resumption from standby in Bootcamp.
So … I’m running Windows XP on a 17″ Macbook Pro with Bootcamp …
Every now and then, when I put the laptop on Standby and try to resume work from where I left off, the USB devices stop responding all together.
This is a big problem for me, since
- I put my laptop in and out of standby several times a day
- work off an external 250GB Hard drive.
- am pretty hopeless without a wireless mouse
I poked around online, but didn’t really find anything on Google or at the Apple bootcamp forum.
So I decided to try fixing it on my own.
What I found curious about the problem, was that everytime the usb devices stopped working, I’d get this message in the Event Viewer.
Timeout (30000 milliseconds) waiting for a transaction response from the AppleOSSMgr service.
So I simply restarted the “Apple OS Switch Manager” service and after allowing it to complete … it would fail, but my usb devices would be operational again.
Here’s how to accomplish it, and I hope this helps someone out.
From the command line
- Hit the Apple btn + R … the run prompt should come up
- type in “
cmd“ - type in [
net stop "Apple OS Switch manager"] (note the quotes) - wait for that to complete
- then type in [
net stop "Apple OS Switch manager"]
Visually
- Hit the Apple btn + R … the run prompt should come up
- type in “
services.msc“ - scroll down until you find “
Apple OS Switch Manager” (sort the columns by name to help you find it a bit more easily) - Right Click on it and select “
Restart“ - wait a while … it will take a bit of time to complete and it should actually fail, but after its done you should be able to use your usb device again.
