Boot failed at checkpoint [USBd]

Question

My desktop computer (Dell dimension series 4550) went black screen with flashing cursor. Tried to reboot several times. At first got:

“Boot failed at checkpoint [USBd] – Error 8602 – Auxililiary device failure – Keyboard failure”

Tried again and just get “Keyboard Failure”. Even swapped keyboards, but the system won’t boot at all. Tried several times to reach setup or (F2 / F12) but it won't go there... Suggestions?

Thanks,

Tim

With your replacement keyboard attached try doing a "hard" reset of the NVRAM by removing the motherboard battery. Just follow this procedure.......

With the machine unplugged from the wall remove the battery from the motherboard. Then with the machine still unplugged press the On button for several seconds to dissipate any remaining electrical charge on the motherboard. Then re-install the battery, plug the machine back into the wall and see if it will boot normally.

If that doesn't resolve the problem then disconnect all the USB devices plugged into the system and try clearing the NVRAM again.

I have a similar problem with my usb mouse. I have posted to mouse keyboard section. See my sad sad story there. I am determined to figure this out.

Try unplugging your usb (?) Keyboard, not a ps2 keyboard. Plug it in after you get to the desktop. USB Keyboard only! Not a very good answer, but at least you can get in.

I have a Dell 4600. I just bought an Epson CX4800.

When the printer's USB wire is connected to the computer, the computer
will not boot; the blinking cursor described in the first note applies.

If, during the boot process, I pull the USB wire out of the socket, Windows XP
will only then continue to boot. It seems to me that Windows is looking to
that USB port as a boot device (which it obviously is not). After I boot
normally, I can replug in the printer's USB port and continue normally.

I have tried this in several USB outlets with the same effect.

I have tried this with the USB connected and the printer OFF, with the same
effect. I must disconnect the USB port during the boot process or the
machine will not boot.

Here is what Epson Customer support said:

---------- Forwarded Message ----------
Thank you for contacting the Epson Connection.

This issue has been reported on the Dell Dimension 4500c and the Sony Vaio
RX series of computers, though it may also occur on some other computers.
When the BIOS of these computers sends the query during bootup to the Epson
multi-function device, the query is ignored by the Epson product which
causes the computer to hang during its boot. This problem has been reported
on some Dell 4500 computer systems using the Phoenix BIOS PLUS v.1.10 A06
ROM chip and on some Sony Vaio RX systems using the Award Medallion BIOS
v.6.0 ROM chip. The best thing we can suggest to do would be to contact
your computer vendor for a possible update\resolution for this issue.

As a workaround, disconnect the multi-function device from the computer and
turn it off. Reboot the computer, then reconnect the multi-function device
to the computer’s USB port and power it back on. This will allow for normal
operation of both your computer and your all-in-one.

Does Dell have a solution, or I am doomed to unplug and plug in my printer at every boot?

MarkMet, you will need to download the BIOS upgrade to a folder on your hard drive.  Don't save it to the desktop as Windows XP has a quirk which can make deleting this file difficult later.  Once the file is downloaded to a folder on your hard drive then simply run the file from Windows.  Prior to doing the update I would close out all unnecessary Windows applications running in the background and disconnect all unneeded USB devices.  This will lessen the chance of Windows hanging during the reboot phase of the BIOS update.  Also do not interrupt the BIOS upgrade while it is in progress or do the upgrade if conditions might indicate a possible power outage could happen such doing the update when there is a thunder storm happening outside.  An interrupted BIOS update can corrupt your currently installed BIOS which may require a motherboard replacement to fix.  Fortunately the actual time it takes to update your BIOS is less than 30 seconds so your exposure to potential problems in minimized.  If your cautious about updating the BIOS then I would try adjusting those BIOS settings I mentioned earlier before doing the upgrade.

As a user, I know enough to be dangerous. I am afraid to tinker with the BIOS because it sounds like self-brain surgery.  If I download a new BIOS, what does this do? Is it 'download and install' and I'm done? Thanks for the rapid response.   Mark Message Edited by MarkMet on 02-13-2006 09:09 AM

MarkMet, as far as BIOS options have you tried disabling the option for USB Emulation?  This option will be found in the Integrated Device sub-menu of the BIOS Setup.  The downside of disabling this option is that if you have a USB - wireless keyboard it will no longer function during Windows XP re-installs or when accessing the BIOS.  Basically with this option disabled the USB ports should be inactive until Windows loads the necessary USB drivers.  The other thing is to check your Boot Sequence to see that no USB device is set before the hard drive in the boot order.  Not sure what devices are listed in your model's Boot Sequence, but it is worth a look.   Also you might consider updating the BIOS to version A12 if you don't have it installed already.  In that version there was a fix related to the system hanging when USB hubs were used.  Although you have a problem with the printer, the BIOS update might have a side benefit of resolving your problem as well.  Click here for the A12 BIOS update.

I just had the same boot failure with a HP Photosmart 3210. As soon as I read your message I pulled the USB printer cable from the Dell and it booted right up. Thanks for the input, it saved me hours of trying to figure this one out.
