It turns out I was just lucky once. Identification does not work
anymore, what's happening is
simply that dib7000m_read_word() always fails in i2c_transfer(). As it
worked once, I'm

I also tried connecting the stick to another USB controller (a NEC
chipset, on a PCI card), instead
of my motherboard's controller, with the same result.

dib7000m_identify(). Then after having read 10240 bytes, the card was
recognized ! Here's
the kernel log:
