Eu tenho um adaptador usb barato e o uso em uma caixa minúscula do CentOS 6.7, quando eu conecto o adaptador, ele é reconhecido como um dispositivo usb, mas não como um adaptador ethernet, embora tenha carregado esses módulos do kernel:
dm9601 7261 0
usbnet 38366 1 dm9601
mii 5376 3 dm9601,usbnet,r8169
e isso que recebo de dmesg :
usb 2-1.2: new full speed USB device number 3 using ehci_hcd
usb 2-1.2: New USB device found, idVendor=0fe6, idProduct=9700
usb 2-1.2: New USB device strings: Mfr=0, Product=2, SerialNumber=0
usb 2-1.2: Product: USB 2.0 10/100M Ethernet Adaptor
usb 2-1.2: configuration #1 chosen from 1 choice
por outro lado, ele funciona imediatamente depois de ser conectado a uma máquina Ubuntu, com essa saída de dmesg :
[ 1398.631380] usb 6-1: new full-speed USB device number 3 using ohci-pci
[ 1398.796441] usb 6-1: New USB device found, idVendor=0fe6, idProduct=9700

[ 1398.992407] dm9601 6-1:1.0 enx00e04c534458: link up, 100Mbps, full-duplex, lpa 0xFFFF
Como posso acionar o módulo dm9601 para reconhecer o dispositivo?
EDIT: saída de modinfo dm9601 no CentOS
