Link #1 I gave (Your Laptop) - Go to the Bottom - Under "Support" Column, click "Drivers and Downloads, then Click "Laptops", then "Inspiron", then "E1705". VOILA!!! All of your drivers.
I see no USB Drivers per-se - please note ICH5 (6, etc) is a different chipset than 945GM. Don't confuse the two.
Link #2 is for the Documentation (may already be on your Resource CD).
Please note that -
1 - Resource CD is more than likely OLDER drivers than...
2 - What is on the Dell Website (updates since Dell issued the Rsrc-CD) and
3 - Usually there are (but not ALWAYS) Newer Drivers for a given piece of Hardware - Use ONLY the Newest! It serves NO PURPOSE to include Old then New. (Kind of like Installing WMP10 then WMP11...)
Going back to Link #2 - Specs
six 4-pin USB 2.0-compliant connectors
This is in reference to the ICHxUSB "drivers" (which are for 82801) and XP generally provides USB except in special cases. If you don't see them on your Resource CD or the Dell Website, I'd say they are not for your Laptop.
Please note that Chipset Packages are just that - they are for MULTIPLE Chipsets (i.e. PACKAGES). For all that it matters, you can needlessly include ALL of them but the Install will only use what it FINDS that it NEEDS.
Do you already have XP installed on it? If so, try looking in the Device Manager. In there you will see SPECIFICALLY what Devices exist.
Finally, if you had downloaded the "Ponch" package and the associated docs, you would see that YES, it does indeed include EVERYTHING that you already "downloaded" except... NEWER! Just because it doesn't specifically state USB, has no bearing.
Go here and browse around. Heck I even have a VIA Chipset and my OS found the latest drivers.
Not to totally miss the boat, here
is where Ponch undoubtedly found the Chipset Drivers. Look there too.
A "google" on E1705 and "USB Controller" implies
the ICH7xxx.INF (82801G) set should be included.
