USB hub turns off for no reason

Nikosapi · 08-18-2004, 04:33 PM

I've got a problem with a usb hub that turns off after an unspecified amount of time. The hub is powered off the usb port. It used to work fine until I formated my hard disk. I know the problem isn't because of a lack of current from the usb port because I once had a webcam, a printer and two mp3 players attached to it. Normaly I only have an Mp3 player and my printer attached to it so I dont see a problem there. I have Toshiba Portege 3110ct with a network port replicator (which is were the hub gets plugged into because it's a very small notebook). I have a usb port on the notebook (which does seem to work, I haven't had time to test it) but it's very inconvenient to have to plug into there.

If it matters I have:
-windows 98 se
-norton 2003
-opera 7.23
-RAM idle pro
-128mb RAM
-300MHz processor
-6.4Gb hard disk
-HP printer (usb)
-RCA Lyra Mp3 player (usb)

P.s. could it be the BIOS because I have usb legacy emulation disabled.

Since most self-powered hubs have a power connector, it's pretty simple to try powering it to see if that solves the issue. The most common problem is overloading the .5A maximum output of the USB port and having it shutdown.
