The adomax device is a virtual qemu "tablet" used to provide absolute mouse coordinates. In other words it helps with mouse pointer synchronization between the host and vms. You may have noticed that the device is picked up by sys-usb's input-proxy sender as a HID device, which is why you may get a popup dialog (if qubes.InputKeyboard policy is set to 'ask') - even if you don't have a usb keyboard. > > > Best regards > Ed Alvarez > > > > [code] > > [someuser@sys-usb]$ sudo lsusb -v > > (...) > > Bus 005 Device 002: ID 0627:0001 Adomax Technology Co., Ltd > Device Descriptor: > bLength 18 > bDescriptorType 1 > bcdUSB 2.00 > bDeviceClass 0 > bDeviceSubClass 0 > bDeviceProtocol 0 > bMaxPacketSize0 8 > idVendor 0x0627 Adomax Technology Co., Ltd > idProduct 0x0001 > bcdDevice 0.00 > iManufacturer 1 QEMU > iProduct 3 QEMU USB Tablet > iSerial 5 42 > bNumConfigurations 1 > Configuration Descriptor: > bLength 9 > bDescriptorType 2 > wTotalLength 34 > bNumInterfaces 1 > bConfigurationValue 1 > iConfiguration 7 HID Tablet > bmAttributes 0xa0 > (Bus Powered) > Remote Wakeup > MaxPower 100mA > Interface Descriptor: > bLength 9 > bDescriptorType 4 > bInterfaceNumber 0 > bAlternateSetting 0 > bNumEndpoints 1 > bInterfaceClass 3 Human Interface Device > bInterfaceSubClass 0 > bInterfaceProtocol 0 > iInterface 0 > HID Device Descriptor: > bLength 9 > bDescriptorType 33 > bcdHID 0.01 > bCountryCode 0 Not supported > bNumDescriptors 1 > bDescriptorType 34 Report > wDescriptorLength 74 > Report Descriptors: > ** UNAVAILABLE ** > Endpoint Descriptor: > bLength 7 > bDescriptorType 5 > bEndpointAddress 0x81 EP 1 IN > bmAttributes 3 > Transfer Type Interrupt > Synch Type None > Usage Type Data > wMaxPacketSize 0x0008 1x 8 bytes > bInterval 10 > Device Qualifier (for other device speed): > bLength 10 > bDescriptorType 6 > bcdUSB 2.00 > bDeviceClass 0 > bDeviceSubClass 0 > bDeviceProtocol 0 > bMaxPacketSize0 64 > bNumConfigurations 1 > can't get debug descriptor: Resource temporarily unavailable > Device Status: 0x0000 > (Bus Powered) > > (...) > > [/code] > -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
