altera 11 usbblaster ubuntu 11.04

Hello all,

I am running into the dreaded ubuntu usbblaster issue. I am on ubuntu 11.04 32 bits with Altera 11 (which is supposed to be better). I got this to work using altera 10 with earlier ubuntu, but no cigar with the current permutation. Any hints on how one might fault isolate this issue are appreciated.

$ jtagconfig

1) USB-Blaster [2-4]

020F30DD

And nios2-download always gives this error.

"There are no Nios II CPUs with debug modules available which match the values

specified. Please check that your PLD is correctly configured, downloading a

new SOF file if necessary."

I do repeated download a new SOF file with the reference design from altera (and that completes w/o errors), and also use the power up reset reference design w/o any success.

I have this in my /etc/udev/rules.d/40-altera-usbblaster.rules (I tried some the other variations being passed around on the web and they dont appear to work complaining that there isn't sufficient privilege to access the port)
