Strange RFID behaviour and BSOD

I am experiencing a strange issue with an RFID Pad and a BSOD.

Dell Optiplex 7010, Win7, 64bit, Intel Corie 7

The issue is that I receive a BSOD just before the login screen appears. However if I unplug the RFID pad from it's USB port at start up, the PC shows the login screen and all is well. Then I need to plug in the RFID pad again. Then randomly after an unspecified period of time I will receive another BSOD.

I know this issue is related to the RFID pad as when it's removed completely I never have any issues whatsoever. There are no error logs that give me any clues as to what's going on.

The thing is, I have another Dell Optiplex 7010, exact same specs, with the exact same RFID pad and driver... which works, never any issues! So I've tried to clone this HDD, and the problem still persists. I've even replaced the motherboard.

Things I have tried so far (with no success);

• Restored pc
• Reformatted hard drive
• Re-installed minimal operating system (only Office)
• Re-installed only operating system (only Windows)
• Installed various driver versions
• Cloned an existing (working) PC
• Replaced motherboard
• Analysed error logs
• Written custom start-up/shut-down scripts (enable/disable ports at login/logout)
• Experimented with 3rd party software (devcon.exe)
• Used ENVy Computer Compare (no differences spotted)

My next step is to try a completely different make/model of PC, but that still doesn't answer my question as to why it's happening.

I've contacted the developers and apparently this is a 'known issue' which is driver-related. I'd just like to know if there's any way I can'work around' their known issue?

Can anybody else think of what the problem could be?

I have included the dump analysis if it means anything to anybody?

EXCEPTION_CODE: (NTSTATUS) 0xc0000005 - The instruction at "0x%08lx" referenced memory at "0x%08lx". The memory could not be "%s".

There are a few potential issues which may be causing this exception to occur.

1. It could be memory which is going bad (maybe, this would persist through os reinstalls)
   • Try removing one of the memory components from the machine and/or replacing.
2. Outdated drivers (possibly)
   • Visit the manufacture's website, download a newer driver.
   • Attempt to downgrade the OS and see if the issue still exists.
3. Potential hardware conflicts (possibly)
   • Unplug any other devices from the machine and see if the error goes away.
4. Or a system related issue (unlikely)
   • Run sfc /scannow from the cmd shell.
