Altera USB-Blaster + Olimex OCD

Has anyone gotten this to work.

It seems tha whichever I plug in second won’t work correctly.

The problem seems to happen more with the Altera device, as I could not connect it with a rockylogic ANT16, but culd connect the olimex one and the rockylogic one together without problems.

Even more strange, if I have the altera one connected and try to run the OpenOCD, I get these messages:

Info: openocd.c:82 main(): Open On-Chip Debugger (2006-08-31 15:00 CEST)

Error: ft2232.c:966 ft2232_init(): unable to open ftdi device: 2

Error: ft2232.c:981 ft2232_init(): ListDevices: 1

Error: ft2232.c:983 ft2232_init(): 0: USB-Blaster

Any ideas?

Thanks,

Ricardo

That sounds like a USB current limit issue. Are you plugging these devices into some sort of unpowered USB hub, perhaps?

No, I’m connecting directly to the PC MB, and to a different connector pair.
