The original post was with USBtiny with firmware 1.04. I upgraded USBtiny to 1.07 and I still can observe this problem.
To find USBtiny firmware version: $ sudo lsusb -v | grep -A2 0x1781 idVendor 0x1781 Multiple Vendors idProduct 0x0c9f USBtiny bcdDevice 1.07 And I want to add another bug with avrdude (or USBasp). I see it when I work with AT90S2313, it is legacy chip that was replaced with ATtiny2313. I can read flash only once, when I try to read it for second time, I get an error. I have to replug my USBasp programmer and I can read flash again. It is 100% repeatable pattern. Read flash of AT90S2313, first time, we can read it: $ sudo avrdude -c usbasp -p at90s2313 -U flash:r:xx.bin:r -F -B5 avrdude: set SCK frequency to 187500 Hz avrdude: AVR device initialized and ready to accept instructions Reading | ################################################## | 100% 0.01s avrdude: Device signature = 0x1e9101 avrdude: reading flash memory: Reading | ################################################## | 100% 8.19s avrdude: writing output file "xx.bin" avrdude done. Thank you. Try again, and we have an error, target doesn't answer: $ sudo avrdude -c usbasp -p at90s2313 -U flash:r:xx.bin:r -F -B5 avrdude: set SCK frequency to 187500 Hz avrdude: error: programm enable: target doesn't answer. 1 avrdude: initialization failed, rc=-1 avrdude: AVR device initialized and ready to accept instructions avrdude: Device signature = 0x588460 avrdude: Expected signature for AT90S2313 is 1E 91 01 avrdude done.
