Confirmed. Turns out my device was dead - I exchanged for a new one
of the same type and tested again. It worked on the first try, both
for ohci and ehci.
EHCI is of course faster: for a quite old 40GB harddisk, I got
around 51-53MBit/s bandwidth for reading a single, large file (around 3GB)
For a newer one, I got 120-140MBit bandwidth with the same test.
Writing is about as fast. I think this is quite near the effective
sequential write/read bandwidth of that drive.
One time during an 30GB transfer from the drive, I got a SCSI error
from the emulation. But it seems no data was lost. I have now
read/written 30GB to/from two drivers and encountered no errors.
So the driver seems to be very stable. Good work!
I'm using the USB 2.0 drivers from the plain 2.6.11 debian kernel
(self-compiled with a few patches). I will switch off USB_DEBUG now
and reboot - I have a 4GB(!) /var/log/syslog
Best,
Alex
