I have a problem with my PEAK Dual DVB-T PCI Card. When my HTPC has been in an S3 sleep for a while when it awakes it 'looses' the DVB-T card. When working ok its listed as a AF9015 BDA device under Sound, Video and Game Controllers. But when it dissapears its listed as an unrecognised USB device under System Devices. The only way to get it back is to power the HTPC off and pull the power cable out for 10 seconds. On reboot its all ok again.
It only seems to happen after an extended sleep (such as overnight).
I am using Windows 7 64 Bit with Media Centre.
