# /etc/udev/rules/42-qemu-usb.rules: qemu emulated usb hid devices # $Id$ # # There are a number of modifiers that are allowed to be used in some # of the different fields. They provide the following subsitutions: # %n - the "kernel number" of the device. # For example, 'sda3' has a "kernel number" of '3' # %k - the kernel name for the device. # %M - the kernel major number for the device # %m - the kernel minor number for the device # %b - the bus id for the device # %c - the string returned by the PROGRAM. (Note, this doesn't work within # the PROGRAM field for the obvious reason.) # %s{filename} - the content of a sysfs attribute. # %% - the '%' char itself. # # Try not to modify this file, if you wish to change things, create a new rule # file that can be run before this one. # # # Enable autosuspend for qemu emulated usb hid devices. # # Note that there are buggy qemu versions which advertise remote # wakeup support but don't actually implement it correctly. This # is the reason why we need a match for the serial number here. # The serial number "42" is used to tag the implementations where # remote wakeup is working. # ACTION=="add", SUBSYSTEM=="usb", ATTR{product}=="QEMU USB Mouse", ATTR{serial}=="42", TEST=="power/control", ATTR{power/control}="auto" ACTION=="add", SUBSYSTEM=="usb", ATTR{product}=="QEMU USB Tablet", ATTR{serial}=="42", TEST=="power/control", ATTR{power/control}="auto" ACTION=="add", SUBSYSTEM=="usb", ATTR{product}=="QEMU USB Keyboard", ATTR{serial}=="42", TEST=="power/control", ATTR{power/control}="auto"
