I have the SpokePov 1.0a kit (according to PCB text, I believe the bag label said 1.1) and a Parallel dongle, XP on a desktop computer. All lights flash up in order when I connect batteries (then one LED at the end stays on at one side of the SpokePov, on the other side it is the 6th from the button -- see image). I have installed giveio and the dongle passed the communications test, using a MultiMeter.. I can connect to the SpokePOV, read from it (will make the wheel entirely red on my screen,
it sounds like your spokepov is working just fine but that the EEPROM itself is bad. or it could be the wiring to/from the eeprom.
if you have more than one spokepov I would try each of them. the 4k eeproms are preprogrammed these days. so if you have another one try reading from it BEFORE you write to it and see if something shows up. should be like a biohazard.
make sure the EEPROM is in the right way
make sure none of the EEPROM pins are bent so that they are not in the socket
only use the latest software. thats v1.4
try changing the rotation offset. does that 'stay'? or can you not actually change it.
i have removed the enormous images. in the future, only post links to the images. thanks!
