3g上网卡如何bonding成一块提高带宽？

goon86

你好，系统有两块3g上网卡，usb的，相当于两块usb modem，插进去后系统生成/dev/ttyACM0设备，通过pppd 拨号/dev/ttyACM0 和/dev/ttyACM1 拨号上网，一块的速度太慢了，想用bonding把这两块usb网卡捆绑成一块虚拟网卡，bonding似乎只支持eth0等的网卡，请问该怎么办？
/ # ifconfig bond0 192.168.12.1
/ # /sbin/ifconfig bond0 hw ether 22:33:1a:11:11:31
/ # ifenslave bond0 ppp0
bonding: bond0: Warning: The first slave device specified does not support sett.
bonding: bond0: enslaving ppp0 as an active interface with an up link.
/ # ifenslave bond0 ppp1
Illegal operation: The specified master interface 'bond0' is not ethernet-like.
This program is designed to work with ethernet-like network interfaces.
Use the '-f' option to force the operation.

先顶一下，请问有办法把usb虚拟成usb0吗？象eth0一样。ifconfig -a看，没有usb的网口，但pppd拨号后会多一个ppp0

简单点来说就是如何把usb设备虚拟成网卡？请教有人做过吗？
