Hello,
I am very interested in doing some developpment on the genesys driver.
So I tried the genesys driver from the cvs html tree with a lide50
scanner. But it doesn't work on my system because it ends in an usb
IO-error.
e.g. if I try scanimage with SANE_DEBUG_SANEI_USB=128 and
SANE_DEBUG_GENESYS=255,
I get:
amd2800:/home/philipp# scanimage

After scanimage I've got an entry in /var/log/messages:
Apr 8 08:41:05 localhost kernel: usb 3-4: bulk timeout on ep2out
Apr 8 08:41:05 localhost kernel: usb 3-4: usbfs: USBDEVFS_BULK failed
ep 0x2 len 162 ret -110
I think the second message is from drivers/usb/core/devio.c in the linux
kernel source tree
(I am using version 2.6.9):
kfree(tbuf);
if (i < 0) {
dev_warn(&dev->dev, "usbfs: USBDEVFS_BULK failed "
"ep 0x%x len %u ret %d\n", bulk.ep, bulk.len, i);
return i;
}
return len2;
I don't know what to do to prevent this IO-error.
Thanks for helping
Philipp
