Problem with USBOHCD.SYS from

Reported by: losepete Owned by: erdmann
Priority: major Milestone:
Component: basedrv Version:

This was originally posted in comp.os.os2.misc/Update to USB host controller drivers: but does not seem to have had any response to date:-

There seems to be a problem with the included usbohcd.sys driver; usbehcd.sys seems to be working fine but cannot test usbuhcd.sys.

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. AMD64x2 4400 cpu

Relevant config.sys lines:- PSD=ACPI.PSD /SMP /PIC
