Details:

I am using USBTiny programmer with AtTiny2313. When programming whether from
Eclipse or Therminal on XUbuntu 16.04, 64-bit, I get error:
....
avrdude: verifying ...
avrdude: 2042 bytes of flash verified
avrdude: reading input file "CDC.eep"
avrdude: input file CDC.eep auto detected as Intel Hex
avrdude: writing eeprom (128 bytes):

Writing | ################################################## | 100% 21.47s

avrdude: 128 bytes of eeprom written
avrdude: verifying eeprom memory against CDC.eep:
avrdude: load data eeprom data from input file CDC.eep:
avrdude: input file CDC.eep auto detected as Intel Hex
avrdude: input file CDC.eep contains 128 bytes
avrdude: reading on-chip eeprom data:

Reading | ################################################## | 100% 1.94s

avrdude: verifying ...
avrdude: verification error, first mismatch at byte 0x0000
         0x00 != 0x43
avrdude: verification error; content mismatch


When I try to read fuses or device ID, Eclipse repports it can not understand
avrdude output.

By using the chip, I verified that the EEPROM was written all 0x01 except for
last three bytes which were fine.

I tried the same code and the same operations on Windows7 64-bit and
everything works fine. The EEPROM gets written OK, Eclipse reads avrdude
output OK.

I tried the latest avrdude6.3 and the result is the same.
