Epox 9NPA+ Ultra issues with USB?

Nothing major but every time I have certain USB devices plugged in at boot my computer will hang and was wondering if anyone had any ideas on this one??

For example my old Microsoft Intellimouse Explorer will sometimes hang the PC at boot and my Apple Ipod Shuffle will always hang the system at boot. As soon as I unplug either the system starts up fine and then after it is up I can plug them back in and work normally...

thoughts appreciated, thanks
 
I had a problem with my old USB 1.1 Hub, when it was attached it would cause cold boots to hang at the info screen for up to 2 minutes (warm boots did were fine). I replaced it with a USB 2.0 Hub and everything is fine now. Took me a while to realize what the problem was, tore apart almost the entire machine before I found it.
 
the Hub I use is a USB 2.0, one of those funky belkins with the stacking and two vertical ports however it being a belkin might be my problem in and of itself 🙂
 
Is your hub self-powered? Does the problem happen with both cold and warm boots? Try disconnecting the hub and see if it helps or not.
 
This brings back memories.... I have an HTPC built around an MSI RS480M2-IL motherboard, and I had a problem with rebooting (not cold boots) when a Buffalo wireless USB device was attached: the system would freeze during post (usually during the memory check), and the only resolution was to to switch off the power supply. (Took awhile just to figure out that it was the Buffalo device that was casuing my problems!)

Either of the following resolved my problem:
(1) Downspeeding the USB ports to 1.1 from 2.0 in BIOS (probably not something you'd want to do since it'd slow Ipod transfers down to a crawl)
or (2) Attaching the wireless USB device to a self-powered hub

At the time, the speculation in the MSI support forum was that certain devices drew more power than they should during startup (which in turn provoked a lively discussion as to whether the motherboard maker or the device maker was at fault for this state of affairs).

If you have a self-powered hub, you might try plugging your Ipod into that rather than directly into the computer.
 
The hub is powered and I believe it happens only on reboots however I could be wrong as I haven't looked into it much....

I have had this happen with my mouse and now my shuffle...either way it isn't a big deal, the system boots fine with my IBM 256mb thumbdrive though....I tried turning off USB mouse support in the bios to see if that does anything, I also removed the "other" option I had selected in the boot device menu
