I have a problem with cgminer on my usb erupter.
3.1.1 works fine, but 3.2.1 gives me this never ending series of errors:

[2013-06-08 19:38:12] USB init open device failed, err -3, you dont have priviledge to access - AMU device 1:9
[2013-06-08 19:38:12] Icarus detect (1:9) failed to initialise (incorrect device?)
[2013-06-08 19:38:17] USB init open device failed, err -3, you dont have priviledge to access - AMU device 1:9
[2013-06-08 19:38:17] Icarus detect (1:9) failed to initialise (incorrect device?)
[2013-06-08 19:38:22] USB init open device failed, err -3, you dont have priviledge to access - AMU device 1:9
[2013-06-08 19:38:22] Icarus detect (1:9) failed to initialise (incorrect device?)
.....

The only usb connected mining hardware is the AsicMiner usb Erupter.
I set the same permissions on both 3.1.1 and 3.2.1:

-rwxr-sr-x 1 andrea dialout 304853 May 24 09:46 cgminer-3.1.1/cgminer
-rwxr-sr-x 1 andrea dialout 1160140 Jun 8 19:35 cgminer-3.2.1/cgminer

Running debian 7.0.

cgminer compiled with ./configure --enable-icarus --enable-bflsc --disable-opencl

Try running cgminer with sudo. Normal users generally don't have the right permissions to access raw USB devices. There are some notes about this in the 3.2.1 README.
