(LG) Wireless local loop phone LSP-3500 and USB

[salmanzk]

I have (LG) Wireless local loop phone LSP-3500. This set is connected with computer via USB port. The problem is that my computer hangs up when I try to dial-up internet from this phone. I figured out that the problem lies in USB connection because this set USB connection is not USB 2 compatible. Kindly tell how to configure USB connection to be compatible with USB 2.

Thanks.
