After all the glowing reports here of SP I requested a download. All went well until it rebooted after install and got a BSOD. The culprit was named as ousb2hub.sys. This is produced by "OrangeWare Corporation". Don't remember when or where this installed. If I disconnect my USB drive it will then boot up, but immediately crashes as soon as I plug it in again. I thought it might be ATI interferring so uninstalled it but it made no difference I am running this in 2k SP4 Anyone any ideas on this please?
