ADSL via LAN cable & ADSL via USB cable?

[devilsmaster]

I'm using an ADSL 512kbps connection with ADSL USB modem! but that connection settings are not optimized in my pc! so i bought an Internet connection optimizing software (ashampoo winoptimizer 4), but that software didn't mention an optimization for ADSL via "USB" cable! only ADSL via "LAN" cable is available for optimizing! what should i do ? is it ok to optimize?

i doubt thats gonna do anything to improve your ADSL experience - as to weather or not it can be used for USB cables or Lan cables, i have no idea.
My guess is that its pointless
