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.

Why not, I only don't want to maintain a patch for my device.

I wonder why didn't they use WP pin of the eeprom to avoid write.

Do you know what should be written.
After a quick search, I found [1]. Is that ok ?
