I unzipped the usbxhcd8 package and powered off as it was (past) my bedtime. Today I powered on the system and was surprised to see the boot process stop with this onscreen:- USBMOUSE.SYS: USB MOUSE driver v.1.1 loaded. I rebooted but the boot stops at the same point - I went and made a coffee and the boot process was still at the same point on my return over 5 minutes later. I booted to a cmd line, deleted usbohcd.sys and reinstated the IBM version. I rebooted to a working Desktop without problems. I'm sure that the usbxhcd7 version of usbohcd.sys did not cause any boot problems previously so I unzipped that version and rebooted to check. No problem on reboot, system loaded fine - using it to post this report. Hardware involved:- nVidia nForce430/mCP61 chipset with 1 * usb2 and 1 * usb1 (ohcd) controller.
