      Hi,

Indeed, and I just retried it using the latest kernel (2.6.7-rc2-bk7) and
the problem stays the same; somehow a bulk transport in usb falls in a timeout.
Now the /var/log/kernel mentions:

Jun  6 19:05:01 localhost kernel: usb 1-1: new full speed USB device using address 3
Jun  6 19:06:11 localhost kernel: usb 1-1: bulk timeout on ep3in
Jun  6 19:06:11 localhost kernel: usb 1-1: usbfs: USBDEVFS_BULK failed ep 0x83 len 4096 ret -110
Jun  6 19:06:41 localhost kernel: usb 1-1: bulk timeout on ep2in
Jun  6 19:06:41 localhost kernel: usb 1-1: usbfs: USBDEVFS_BULK failed ep 0x82 len 1 ret -110
Jun  6 19:06:44 localhost kernel: usb 1-1: usbfs: USBDEVFS_BULK failed ep 0x83 len 22 ret -84
Jun  6 19:06:44 localhost kernel: usb 1-1: usbfs: USBDEVFS_BULK failed ep 0x1 len 10 ret -71
Jun  6 19:06:44 localhost kernel: usb 1-1: usbfs: USBDEVFS_BULK failed ep 0x82 len 1 ret -84
Jun  6 19:06:44 localhost kernel: usb 1-1: usbfs: USBDEVFS_BULK failed ep 0x1 len 6 ret -71


See also my report from May 10, see:

http://lists.alioth.debian.org/pipermail/sane-devel/2004-May/010985.html

So I am afraid the problem still persists, with my HP7400C anyway.
