Hi,
Trying with 2.4.19 up to 2.4.20-pre10-ac2 it has not been
possible on my system to use external disks with the isd300a interface
with the ehci-hcd driver. WinME works as expected with high transfer rates
6-8MB/s.
Under Linux reading from FAT32 works for a while but typically hangs after
200MB of a
700MB test-file and needs a power-off/on cycle (ext3 !!).
Writing and acessing ext2 partitions hangs immediately  with ehci
while usb-uhci and usb-ohci both work slow but consistently with the same
system.
ohci and ehci pass through a cardbus bridge (advance) with ohci ok.
What is wrong with ehci-hcd and this system?
There is no message in /var/log/messages indicating the reason.
Debug usb-storage is too verbose and hard to interpret.
Greetings Dietrich
