While we're warning people away from the GenesysLogic chips
The ISD-300 chips appear (to me, at least) to be one of the best
implementations of an USB to ATA[PI] bridge device. I highly recommend
them, if given the choice.
Nice to hear that the ISD-300 seems to be a go
I kind of solved my problems with the Genesyslogic chipset by
changing to an Macpower box with ISD-300A chipset. The funny
thing is that the chipset hides itself as:
P: Vendor=0dc4 ProdID=0001 Rev=11.06
S: Manufacturer=Macpower
Thank you to Dave and Alan for your support tracking down
the problem

On further thought I realized this would have less of an effect than
simply reducing max_sectors even more. Try decreasing it to 64, or even

if anything below 8 would make any difference.

Thanks for your analysis. It seems that the CATC USB tracers
are very expensive, compared to an 35 EUR IDE->USB box.
Maybe the slowdown of the

Tried this with the Intel chipset. Unfortunately it does not prevent
the deadlock of the box...

Applied the diagnostic patch to 2.6.1-rc1 _without_ the recommended
workaround from Alan. Is the attached log what you expected to see?

In your kernel source tree, find and edit the file
