Hi there,

Upon booting up the pc, I repeatedly receive the blue screen of death for the above stop message. I figured it had something to do with the USB driver stack but I'm clueless as how to go about fixing it. I'm running Windows 2000/ on an AMD processor. Help!

Short summary and what the crash means: seeing uhcd.sys on a "DRIVER_IRQL_NOT_LESS_OR_EQUAL" (0xD1) stop means the crash happened in the USB host-controller layer — uhcd.sys is the Microsoft Universal Host Controller driver used by Windows 2000 — and D1 indicates a kernel-mode driver tried to access pageable memory at too-high IRQL (usually a buggy driver or a bad interaction in the USB stack). (learn.microsoft.com)

Why disconnecting the printer often helps: kernel-mode printer drivers can hook into the USB stack and produce exactly this kind of failure. The quickest recovery is isolation: unplug all USB devices, boot Safe Mode (F8), then uninstall the printer (and its driver package) from Device Manager / Print Server Properties and stop the Print Spooler while you remove driver files. If that clears the BSOD, reinstall using either the vendor’s updated kernel driver or a generic driver; test before reattaching other USB hardware. Microsoft also documents UHCD-related USB/BIOS conflicts that were addressed in Windows 2000 updates — applying the appropriate service pack or chipset updates is part of a full fix. (support.microsoft.com)

If the problem continues: collect the minidumps (typically C:\Windows\Minidump) and analyze them with WinDbg (!analyze -v) or a lightweight viewer (BlueScreenView/WhoCrashed) to see which module is blamed. If a third-party driver is suspected but not obvious, enable Driver Verifier for suspected non-Microsoft drivers to force the offending driver to fail and point to the culprit — but back up first and be prepared to disable verifier (verifier /reset) if the system becomes unbootable. (learn.microsoft.com)

Tie-back to the thread: ’s disconnect-and-uninstall approach is the right first step for ; ’s reminder to update drivers is the next step after isolation. If those fail, share a minidump and the exact faulting module name (the dump analysis) before doing hardware swaps.

Have you a HP printer attached? Disconnect it, boot into safe mode and uninstall the printer.

If that fixes the problem, search HP's site for a fix or patch.

you should have just tried to just update all the drivers.
