Hi Hans, This is similar to a problem I reported some time ago:
https://lore.kernel.org/lkml/2268131.Lc39eCoc3j@kreacher/ and the device affected by it is the same. The symptom is simply that the mouse just doesn't work (no reaction). If I do "rmmod hid_llogitech_dj", it says "Killed", but the module does go away and the mouse starts to work (through the generic code I suppose), but then the machine hangs on attempts to suspend (nasty). Reverting all of the hid_llogitech_dj changes between 5.2 and 5.3-rc1: dbcbabf7da92 HID: logitech-dj: fix return value of logi_dj_recv_query_hidpp_devices 39d21e7e0043 HID: logitech-dj: make const array template static 423dfbc362b7 HID: logitech-dj: Add usb-id for the 27MHz MX3000 receiver helps here, but the first two don't really look like they can make any difference, so I guess I'm an unlucky owner of a MX3000 that doesn't quite work as expected. Any help will be appreciated. :-) Cheers, Rafael
