I made the open programmer - thanks for the great work - but I have problems with it when using i2c eeprom. It constantly indicates an error when writing, and the content read is different each time it is read - as if it were completely unstable. Do you have any idea where to start searching? I also attached a log file - maybe it helps; it doesn't tell me anything ... :-) Thank you very much for your help in advance!

Which I have tried so far:
Another 18F2550
Each IC socket power pins got a 100nF
Other USB sockets (also 2.0 and 3.0)
Another USB cable
10 uF replacement for 10-100uF spacing
I washed the PCB with alcohol
Trying not only with EEPROM, but also with PIC16F628A - the phenomenon is the same: as many reads, as many lengths and contents, and error messages when writing (also in different places and numbers) Finally, I put it under windows10 - the same error symptoms!
*My enviroment is:
I7-4470@3,5GHz
32GB RAM
Geforce GTX660
SATA3 HDD-s
Linux Debian Buster with KDE windows manager, 5.6.14 Kernel*
Lately I received a couple of complaints about the same issue, always involving Linux.
The problem seems to be related to the low level IO through /dev/hiddev.
I am testing a new method that uses /dev/hidraw.
If you want to try it as well please contact me via email.

And these are the results of two consecutive readings - this is the first
...and this the second (a few seconds later)
