Because it does not matter, what I put into usbvid/usbpid, the resulting error message is always:
- - -
avrdude: usbdev_open(): did not find any USB device "usb" (0x03eb:0x2104)
- - -
Why that 0x03eb:0x2104 in the error message?

I provided 3 results with different usbvid/usbpid, the 1st one was your advice. Sorry, if I was unclear.
Again this is the variant, you provided with the result:
- - -
root@home2l:~ #	cat ~/.avrduderc
default_programmer = "diamex-avr-usb";
programmer
 id    = "diamex-avr-usb";
 desc  = "Diamex AVR USB Programmer";
 type  =  "stk500v2";
 connection_type = usb;
 usbvid     = 0x16c0;
 usbpid     = 0x2a9b;
;

root@home2l:~ #	avrdude -p t85 -vvv -t

         System wide configuration file is "/usr/local/etc/avrdude.conf"
         User configuration file is "/root/.avrduderc"

         Using Port                    : usb
         Using Programmer              : diamex-avr-usb
avrdude: usbdev_open(): did not find any USB device "usb" (0x03eb:0x2104)

avrdude done.  Thank you.

OK. Thanks for the explanation.
