I have the same problesm, at the moment I'm using the 2.0 seagate.c with SEA_BLIND_TRANSFER undefined. I've also, turned on the NOMSGS define, as it was having timeout problems with 2 devices attached. I notice that yours is the TMC-885 like mine. The main work was apparently done on a ST02. My theory (which I'm in the process of building a kernel to confirm) is that the TMC-885 series does not support disconnect/reconnect at all well. I'll be hacking on the latest version of the driver soon if my experiment turns out to support this hypothesis. Stephenhome | help
