USB 2.0 pen drive crashing XP

**richardw** · March 4th, 2004, 05:36 AM

Hi,

I've just bought myself a ByteStor 256Mb USB2.0 pen drive, which is starting to drive me crazy! I use it on 3 machines (work, home and college) and its fine on the work (Compaq Evo - Win XP SP1) and college (Elonex - Win2K) boxes, but constantly crashes my home PC. The box is home built - Abit KT7A v1.3 mobo, GeForce FX5200 graphics, Ali USB 2.0 pci card, Win XP SP1, - and each time I try and stop the device to remove it I get a quick BSOD, then the PC reboots. If I try and eject the device, same thing. If I leave it connected for a while, same thing again after a random amount of time.

I've tried all the latest drivers I can think of (except flashing the BIOS - thats to be done this weekend), checked all patches I can think of, including getting the USB 1.1 & 2.0 patch from M$. Nothing seems to help.

I've contacted ByteStor tech support (4 days ago) but I haven't had a response yet. I really don't don't want to send the drive back as it was a great price (cheapskate, I know), and I use ByteStor CF cards in a number of devices and they've always been great. Anyone any ideas what I can do to try and resolve this?

If you are plugging it into the ALI usb 2 card, it may be the card is not supplying the right voltage, or even the psu in your computer is not supplying the right voltage to the motherboard. In order for you to read the BSOD and post it here, right click my computer, properties, advanced tab, startup and recovery button, uncheck automatically restart...Then when it Bsods, it stays like that till you manually restart the computer.

As I said, if you would post the entire message here, we can help further.

Sorry for the late reply and Welcome to Windrivers!

Thanks for the advice NooNoo. I'm also getting the same results when I use the USB 1 ports, so I guess the power supply could be the culprit. I'll get the STOP message and post it here later.

Thanks for your help so far....!

OK, the STOP error I'm getting is:
BAD_POOL_CALLER
STOP:0x000000C2(0x00000007,0x00000CD4,0x020c0003,0 x8928D1E0)
A quick google shows this as a kernel mode process or driver performing a memory operation, typically due to faulty driver or software...?
Not sure where this leaves me. Any ideas would be much appreciated!

Leaves you with an interesting set of possibilities, the first being that your motherboard drivers are not correctly installed. This ALI card, are you just using that or do you get this crash on every usb port, 1.1 or 2?

Edit: hmmm ms says it may be as simple as your AV

I used to get crashes with powered USB devices (like my scanner, bluetooth, etc) until I made use of a powered hub.

For all one will cost you (about £10-£15) it would be worthwhile, especially since you could connect even more devices without your PC moaning.

Drivers might be a problem too, but my money is on your board not being able to supply sufficient power to the devices connected to it.

Is this 'Physic Tech Aura' in reverse ? ... he got straight to his own issue .. though I think you 'have it' on the 'not correctly installed' line - I'm guessing its acpi issues & 'allocation' ...

A quick google shows this as a kernel mode process or driver performing a memory operation, typically due to faulty driver or software...?

Uncle Billy tells you how to 'debug' it (which if you can get it working ought to reveal what's 'bad' ) - but methinks a 'slot shuffle' might cure it (so try the pci usb card in a different slot), as ...

The current thread is making a bad pool request. Typically this is at a bad IRQL level or double freeing the same allocation, etc

Go get that bios update too (my reading is that it 'can' affect irq assignment - & this ain't a motherboard 'designed for xp' so acpi & resource allocation may be 'tricky' )

Had the same problem on 2 home PC's (One W2K, one WIN XP). Tracked the problem down to my AV software which was CA E-Trust v6.1. Upgraded E-Trust to V7.0 and hey presto, all now working fine on both machines. Simple when you now how!
