插上网卡可以发现网卡:
dmesg |grep sio

usb2: USB revision 1.0

启动发现如果插上USB mouse,会在启动时出现死机,如果不插上正常,
demsg |grep 18发现irq冲突,uhci2和cbb2都使用irq18
如下:
uhci2: <UHCI (generic) USB controller> port 0x1860-0x187f irq 18 at device 29.2 on pci0
cbb0: <PCI-CardBus Bridge> mem 0xd0006000-0xd0006fff irq 18 at device 9.0 on pci5
sio4: <Vtion Vtion-V1806 Wireless> at port 0x2f8-0x2ff irq 18 function 0 config 13 on pccard0
