Jun 27, 2005 - The B-Control Audio BCA2000 is a high-speed USB 2.0 multi-channel audio/MIDI interface with ADAT® support, multi-channel outputs, and an. Feb 5, 2009 - This package contains the files needed for installing the Behringer BCA2000 DJ Controller Driver. If it has been installed, updating.
The improved performance and new features of the BCA2000 Windows XP driver Version 2 include:. Greatly improved stability as compared to the old driver.
Many inconveniences are substantially reduced with the BCA2000 Windows XP driver Version 2. Drastic reduction in system load, giving the user more remaining power resources such as more audio tracks, software instruments and effectsNew switchable USB1.1 mode (for USB2.0 hosts only) with full support for ASIO/WDM that is ideal for applications where system load is critical.
The BCA2000 Windows® XP driver Version 2 will reduce interruptions, audio dropouts etc. New WDM settings page in BCA2000 Control Panel allowing users to select recommended bit depth, sample rate and number of output channels. Greatly simplified driver installation process – simply double click on the “Set-up.exe” For more information or to download of BCA2000 free of charge, visit www.behringer.com.
The BCA-2000 firmware and FPGA code is all contained within Berhinger's BCA2000.sys driver. As the unit at cold boot contains no runnable code or FPGA programming, we must extract the firmware and FPGA code from the driver in order to operate the unit. Examining the driver using a PE dump utility, it has an area called 'PAGEDATA'.

The first part of this data is the 8051 code, in the form of blocks to program over the USB. Each block in in the form: char BlockLen; unsigned short Address; char Type; char Data; // variable length the last block has BlockLen=0, Address = 0, Type = 1 e.g. First block: 0E 00 01 00 90 E6 00 E0 FA 74 E7 5A 90 E6 00 44 10 F0 second block 0E 0E 01 00 00 00 00 00 00 00 90 E6 0B E4 F0 12 0F C8. Second to last block: 01 68 17 00 22 last (terminating) block: 00 00 00 01 For our purposes, I wrote a small programme which took these blocks and created a complete binary 8k image of the firmware, and we download that using the Cypress firmware USB commands, pausing the processor first, and then running the processor afterwards. As soon as the firmware runs, the unit will change it's VID and PID.
After the 8051 firmware in the.sys file comes the FPGA code. In the 2.1.0.6 driver, it starts 8 bytes after the last firmware block. This is downloaded into the BCA-2000 over proprietary USB commands in chunks of 32 bytes.

(vendor commands 0x10 and 0x11 to endpoint 1). The FPGA image starts with FF FF FF FF and ends with 3F FF FF FF. I don't know if there is any structure to the data, I identified what we needed to send by usb sniffing. I extracted the FPGA code into a second binary file for upload.
