All other device IDs are reserved.
1b36 vendor ID
--------------
The 0000 -> 00ff device ID range is used as follows for QEMU-specific
PCI devices (other than virtio):
1b36:0001 PCI-PCI bridge
1b36:0002 PCI serial port (16550A) adapter (docs/specs/pci-serial.txt)
1b36:0003 PCI Dual-port 16550A adapter (docs/specs/pci-serial.txt)
1b36:0004 PCI Quad-port 16550A adapter (docs/specs/pci-serial.txt)
All these devices are documented in docs/specs.
The 0100 device ID is used for the QXL video card device.
