! PLEASE CC to me i'am not registered to this list

i'll try to use the usb-storage with my Sony DSC
but since kernel version 2.4.7 it's seems to be brocken.

look like a problem with the interrupt handling with the
usb-uhci which shares it's interupt with the sym53c8xx driver.

i use a 'dualhead' SCSI controller from DIGIAL with
two 53c875 chipset.

any idea?

cheers

Does the same thing happen with the uhci (JE) driver?
You will also have better luck asking this on the linux-usb-devel
mailing list.

ok, i'll sent it to linux-usb-devel

and it's happen with both, the new and 'old JE' uhci

i'am also took the delay switch on for slow usb-devices
CONFIG_USB_LONG_TIMEOUT=y

but it's doesn't resolve my problem.

thanx for now
