I have an Ubuntu 14.04 system kernel : 3.17.8-031708-generic. I am using Davicom Semiconductor, Inc. DM9601 Fast Ethernet Adapter on USB 2.0. On connecting to LAN I get a speed of one-third of the speed I used to get from my onboard LAN.

lsusb -v shows that my USB Ethernet is being connected at USB 1.10 although the chipset shows USB 2.0 connection and my USB ports are also USB 2.0.

Is there any way to resolve this?
