https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=282144 --- Comment #9 from Gary Jennejohn <gljennjohn@gmail.com> --- (In reply to fjpavon from comment #8) In /sys/dev/usb/quirk/usb_quirk.h there's this quirk: UQ_KBD_IGNORE, /* device should be ignored by kbd class */ so you could try using that quirk with the mouse. The problem is, of course, that ums.c uses this code: /* A match on these entries will load ums */ static const STRUCT_USB_HOST_ID __used ums_devs[] = { {USB_IFACE_CLASS(UICLASS_HID), USB_IFACE_SUBCLASS(UISUBCLASS_BOOT), USB_IFACE_PROTOCOL(UIPROTO_MOUSE),}, }; in the ums_probe(device_t dev) function and UIPROTO_MOUSE is 2. The only solution I can see would be to add some code to ums_probe() to use the idVendor = 0x12c9 and the idProduct = 0x1021 values to change USB_IFACE_PROTOCOL for the mouse to be temporarily set to 1 rather than 2. However, this would mean having to maintain a patch to ums.c. Personally I'd send this mouse back and inform Newmen Tech.,LTD that they're using the wrong bInterfaceProtocol for a mouse. -- You are receiving this mail because: You are the assignee for the bug.
