Internittent BSOD related to USB-Serial Adapter

Greetings all. This concerns a system here at work that I just placed on-line. IT is used to run testing on a product under a Labview Environment. The system is an industrial Rackmount PC.

XP SP3
Mfg: Supermicro
Pheonix BIOS ver. 2.5 (7/24/2008)
2 Gb Ram
Duo-Core 2.2 GHz

System exhibits periodic BSOD. Error is typically IRQL_NOT_LESS_OR_EQUAL. Anywhere from 20 minutes into a test to 4 days. All minidumps point to either ser2pl.sys or usbstore.sys. The bulk (approx. 90+ %) are for ser2pl.sys. The driver is signed and is the latest version (1/24/2009). The adapter is controlling a Lambda Power Supply. I do not have another Power Supply available yet, but am trying to get one. I have also ordered a PCI Serial Card to eliminate the need for the adapter. The adapter is the ONLY device in the system that uses the Ser2pl.sys driver. I have tried all of the following:

Three (3) different USb-Serial Adapters
Removed the PCI-USB cards and plugged directly into MB USB
Changed Baud Rate of connection
Actually swapped out entire computer with the exception of the hard drive. (The required software and support files are extremely numerous and would take quite a while to recreate).

Six (6) of these PC's were purchased as standard configuration on all new systems. I should also tell you that there is an existing system running "The exact same software, with the exact same drivers" running on a Dell Dimension PC. Unless there is something buggy about the actual PC (type of memory, MB, Processor, etc), I am at a standstill on this. I would have sworn swapping the PC would take care of it. I have attached the BSOD Stop Error, along with a Minidump file. The only idea I have left is to actually replace the PC with another Dell of the same type and mount the existing drive as a slave to access the software files. This is killing our throughput and my head is killing me from banging it against the wall. I really need your help.

Thanks

HI John... have not forgotten this. We are contacting the vendor to see how sp3 was installed. There is no entry under add/remove programs and there is nothing that appears to be related to sp3 to use spuninstall command. It appears it may have been slipstreamed during the install.

Will keep you posted...

thanks

okay... there was nothing that could be done with the adapter and no way to remove SP3. I ended up installing a PCI-Serial card and that is working fine. I amnow in the process of ardering a bunch to replace all existing usb-serial adapters.

Joh, I appreciate you taking the time to try to help. I am going to go ahead and close this out.

Thanks again.
