UsbBlaster uneder Linux

Hello,

I have a problem using my UsbBlaster under Linux. I actually have a ByteBlaster MV which works with both Quartus2 programmer and Nios2-IDE (nios2-download), under Windows and Linux.

My UsbBlaster works perfectly under Windows too (Quartus2 and Nios2-IDE), but under Linux it only works for Quartus2, not for the Nios2-IDE. Isuppose it is corrrectly installed since Quartus2 can use it, but there is apparently a problem with nios2-download when reading the timestamp and ID...

Here is what I get when I try a nios2-download first with the ByteBlasterMV

[SOPC Builder]$ nios2-download --cable=1 --accept-bad-sysid sand1.elf -g

and with the Usb-Blaster on the same system :

[SOPC Builder]$ nios2-download --cable=2 --accept-bad-sysid sand1.elf

Does anybody know something about this strange behavior ?

Thanks in advance
