arg.... it really ****es me off.. its the one thing, that makes my setup incomplete

I cant controll anything with the keypad after i resume from standby, and I do not want to restart the carputer everytime I start up the car...

I'we read about some fixes, or updates on Microsoft.com .. but I cant find the same page ... (its impossible to find anything at Microsoft.com)

I found that when I came out of hibernation my USB-Serial for my GPS did not work. Restarting will fix it, but I also found that if you unplug it, and plug it back in it comes up fine. So I wonder if you could rig some sort of relay to allow you to do this automatically... have not looked into that yet though.

I'we noticed that to re-hot plug the device also brings it back... (as well for a restart) .. .but.. Iwe read that the problem is some sort of a "state" problem in registry in windows.. ie. before hibernation, the state of a usb device could be something like this:

xxx.xx.xxx..xxxx.1 .. and after hibernation / suspend the number one would change to "2" ... which would make windows not correctly "talk" to the device ...

anyway..

its really a pain

... iwe finally got Girder up and running, with alot of sweet solutions for controlling my carputer, and everytime I, either have to hot plug the device or restart the carputer

arg..
