Hello,
I am trying to build a P300 based Web Browser. I am running BCI 2000 on a 64bit machine and getting this error

2011-03-18T15:29:18 - Warning: gUSBampADC::Preflight: g.USBamp driver version = 3.2.
2011-03-18T15:29:19 - gUSBampADC::Preflight: Could not find appropriate pass band filter in gUSBamp. Use gUSBampgetinfo tool.
2011-03-18T15:29:19 - gUSBampADC::Preflight: Could not find appropriate notch filter in gUSBamp. Use gUSBampgetinfo tool.


However the same setup on a 32 bit machine works fine.

If anyone has faced a similar error or could tell me where I might be going wrong.

Thanks
nadu

This is a bit of an obscure issue. The problem is that the usbamp stores its filter settings in binary files, but they are only in the correct location for 32-bit windows. The solution is to copy the files from C:\Windows\System32 to C:\Windows\SysWOW64. The files have the format DSP*.bin, e.g. DSPfilter.bin, etc. Copy these, and that should fix the problem.
