A-open XC-cube usb device not recognized.

[gilly1984]

My HTPC has started saying that when i put any usb in, it says it when i try my phone or a usb flash drive, but weirdly the usb receiver for the wireless mouse works fine?

I noticed a while ago that my usb powered external hdd would make weird noises like it was under powered so i had to use a Y splitter to feed it power from 2 usb slots.

Anyone have any idea why this is happening?

Its a A-open xc-cube EZ661

Happens on the front and back usb ports.

Hmm, i will get the dmm on it tomorrow. Hope its not because its not a normal psu.

All caps on the mobo "look" ok, but not checked the psu.

Thank you kc8adu.

Thats what I was thinking, some kind of 'overload'.

Is it possible that you might have zapped the USB port? :/

If there are bad caps in the PSU, then you should list them here, for other web-browsing computer-fixing folks in the future

I haven't seen many issues with badcaps in slim desktops yet on the web.

Turned out to be the xp installation, switched hdd priority and booted into win 7 and it works fine.
