I had to reformat my laptop. I have three USB ports. Two USB 2.0 and one USB 1.0. In the past when I have reformatted the hard drive only the one USB 1.0 port worked until I installed the chipset drivers. This time, I reinstalled the chipset drivers on several different occasions, still I was not able to get the other USB ports to work. Then, I tried to update the BIOS as a last ditch effort. I am particularly in a pickle because I rely upon speech recognition software to do my typing. That requires a USB headset. I do not like using the touchpad, I need to use a USB mouse. With only one USB port functioning I can either use my speech recognition or the mouse but, not both. The laptop is a Dell Inspiron 17r. I do not remember the exact model. It has an i5 processor with 6 GB RAM and a 5400 RPM hard drive. Windows ultimate is the OS.
