My PC doesn't like new USB devices...

I upgraded to Win7 the day after it's release, from WinXP. Did a new install. Things have worked just fine for me after that, except for a driver that I needed to update in the first couple of days (HP scanner didn't get recognized, but update was released a day or two later and all was good then).

Anyway, recently I have been having problems where if I try and plug in a new (to this PC) USB device, it will try and load the drivers, but it fails. Generally, these are various USB Flash drives, but I also received an iPod Touch for Xmas, and the same thing happens with it. Also happens with a digital camera and it's memory card (either via an adapter to directly read the card, or via a USB cable directly to the camera).

I know the devices work because I can access them on other PCs (but those are all XP boxes), and I know the USB port on my Win7 box works because I have a Flash Drive I use daily that still works, as well as several USB peripherals that work fine (HP printer, Logitech wireless mouse, etc).

Any suggestions on what might be going on or what to do here????

The first item I noticed the problem with was my iPod Touch (believe it's a 2nd gen, it's 8 GB). Then, one of my digital cameras, a Casio EX-S10A (it's in the Exilim line). Also tried reading it's memory card with a USB card reader, a Verbatim miniSD/SD reader model #96504. Also tried a couple various USB flash drives...don't have specific model numbers on those - one was a Verbatim, another was a 2GB Lexar, another was a 4GB Sandisk Cruizer.

The system has several USB ports on the back, and 2 on the front (top). I also have a 7-port USB hub. I have Rally 16GB USB Flash drive that will run fine from any of these USB ports. I tried the "problematic" items in various ports - in the hub, in the ports on the top, and in a port on the back. No go.

Let me know if more info would help.

thanks for the tip - I have updated my profile.

My bios version is 1238, and if you look that up on ASUS's website, that appears to be the latest version. Not sure why mine reports that earlier date - ASUS shows 1238 as having a date in Feb 2009.

Other suggestions?

No, I expanded each section of the Device manager and there were no entries with an exclamation mark...
