When you try to download a file from the Internet by using Microsoft Internet Explorer in Microsoft Windows XP, the download stops responding and then times out. The problem occurs when you use a USB modem that has a data transfer speed that is faster than or equal to 240 kilobits per second (Kbps).


The problem occurs because of a limitation in the current USB modem driver (Usbser.sys).
