Comment # 7 on bug 1173085 from Olav Reinert

A forced remove and rescan produced the following output in the system log:

bb:~ # echo 1

Conclusion: Rescan does not help, it just reproduces the "unknown chip" error I
mentioned earlier.

I also verified that I am in fact operating on the correct device:
