It doesn't sound a very good approach the need of recompiling the
driver to
allow it to work with a broken card. The better would be to have some
modprobe
option to force it to accept a certain USB ID as a valid ID for the
card.
The most correct way would be to reprogram the eeprom, by simply
writing to 0xa0 (0x50 << 1) I2C address... There was a thread on the
linux-dvb some time ago.
BTW dibusb_i2c_xfer seems to do things very dangerous :
it assumes that it get only write/read request or write request.
That means that read can be understood as write. For example a program
doing
file = open("/dev/i2c-x", O_RDWR);
ioctl(file, I2C_SLAVE, 0x50)
read(file, data, 10)
will corrupt the eeprom as it will be understood as a write.
Now that I think of that, I run sensors-detect on this machine, may be
this is what trash the eeprom ?
