>Description:
Hi.
After switching from Linux to FreeBSD yesterday, I encounter problems with the
mouse mentioned in the subject. It is neither recognized in the normal boot-up
nor when re-plugging it after the boot-up, which renders the device (my only
mouse) completely useless.
Turning on USB_DEBUG has shown: "usbd_get_string: getting string failed, using
0". So this beauty seems to not understand the string descriptor requests.
I have searched the usb-list and the net, but without any success. Ok, there
was a hint about commenting out the code, but I think this is not the way it is
ment to be. So I decided to have a look into the sources under
/usr/src/sys/dev/usb. In fact, there is already a Logitech iFeel Mouse in
usbdevs, but with a different device id. The listed device is 0xc030 whilst
mine is 0xc032. So I added a new entry "product LOGITECH UN53B 0xc032 iFeel
MouseMan". Actually this did not solve the problem of failing recognition of
the device :-) So I took a closer look on usbdi.c::usbd_get_string() which is
the point of failure and found "if (dev->quirks->uq_flags & UQ_NO_STRINGS)"
which in turn checks the device for being unable to provide the strings
usbdi.c::usbd_get_string() wants to extract. So the next step was to add the
newly created usbdevs entry to usb_quirks.c with UQ_NO_STRINGS as the
corresponding quirk. Now the mouse is shown in command usbdevs, works fine in
moused and under
Xorg. It is successfully recognized as /dev/ums0 4-button mouse with scroll
wheel.
Attached there are the patches of the changes I did. Hopefully they will find
their way into the tree, since there seem to be a lot of people struggling with
that (mouse') problem.
Btw. system is: AthlonXP on VIAKT400A+ (VT82xxxxx UHCI USB) running
7.0-CURRENT-200607.
Best regards,
Heiko
>How-To-Repeat:
restart the system
plug out/in the mouse :-)
>Fix:
add "product LOGITECH UN53B 0xc032 iFeel MouseMan" to
/usr/src/sys/dev/usb/usbdevs
add "{ USB_VENDOR_LOGITECH, USB_PRODUCT_LOGITECH_UN53B, ANY, { UQ_NO_STRINGS
}}," to /usr/src/sys/dev/usb/usb_quirks.c
If needed, I am able to provided patches for those files.
