An Epson Perfection 1240U USB scanner which worked fine with 1.10.1 is now
unrecognized. Pluging and unpluging the USB cord doesn't result in any
kernel message visible in dmesg.
According to the sources we have an entry for your model:
{{ USB_DEVICE(0x04b8, 0x010b) }, 0 }, /* Perfection 1240U/1240Photo */
I'm currently preparing a mass update of USB quirks and it seems like
the vendor ID of Epson has changed. The new entry from FreeBSD device
ID list looks like this:
{{ USB_DEVICE(0x03f8, 0x010b) }, 0 }, /* Epson Perfection 1240U / */
Note the difference between 0x04b8 and 0x03f8. To check that I'm not
wrong, you could change the ID in the uscanner source, recompile the
module, reload it and check again if the scanner is detected:
I tried it and it didn't change anything: no kernel messages either.
However, I found out there's was a difference between a standalone
uscanner module and one compiled in the kernel.
Standalone module:
- original - nothing
- patched - nothing
Uscanner in kernel:
- original - some kernel messages appear at startup
# dmesg | grep uscanner
uscanner0: EPSON Perfection1240, class 255/255, rev 1.00/1.04, addr 2
on uhub0
uscanner0: at uhub0 port 2 (addr 2) disconnected
uscanner0: detached
- patched - some messages about ugen0
ugen0: at uhub0 port 2 (addr 2) disconnected
ugen0: detached
There's definitely something fishy going there.

Then devices should be probed and if there is a better match than ugen and if the ugen device is not open, it should be detached from ugen and attached to the new driver.

I'm not sure I did that with standalone modules. Uscanner in kernel: - original - some kernel messages appear at startup # dmesg | grep uscanner uscanner0: EPSON Perfection1240, class 255/255, rev 1.00/1.04, addr 2 on uhub0 uscanner0: at uhub0 port 2 (addr 2) disconnected uscanner0: detached It's a disconnect message only. - patched - some messages about ugen0 ugen0: at uhub0 port 2 (addr 2) disconnected ugen0: detached It's a disconnect message again only. And it shows that there is no need for patch. Show me the full dmesg with verbose booting, please. I have put a dmesg dump here (uscanner in kernel) : http://www.wolfpond.org/dmesg-dfly-1.11-verbose.txt I have disconnected and reconnected the scanner just after dumping this file. There were only this additional messages: uscanner0: at uhub0 port 2 (addr 2) disconnected uscanner: ops removed uscanner0: detached -- Francois Tigeot
USB scanner unrecognized on 1.11-DEVELOPMENT
Hi, I recently upgraded a machine from Dragonfly 1.10.1 to a recent 1.11.0-DEVELOPMENT (as of today). An Epson Perfection 1240U USB scanner which worked fine with 1.10.1 is now unrecognized. Pluging and unpluging the USB cord doesn't result in any kernel message visible in dmesg. I know the USB stuff has been heavily refactored since the last release. How can I proceed to debug this ? -- Francois Tigeot
