any pc guru's here?

on xp sp2 on ibm x32 laptop if i try and run more than one usb device that requires external power supply at the same time windows doesnt like it (have tried on my other laptop and same issue) I have usb 2.0 ports

I can run multiple devices (mouse, webcam, small 4gb usb drive etc) either on multiple usb ports or even through the same port on usb hub

but if i try and connect external cd burner and large hd that requires power, you cant run both devices, device fails

is there a setting in the power options that needs to be changed??? or any idea's? anyone have same issue?

thanks

nope

laptop has 2 usb 2.0 ports and i connect one device per port

your laptop's power manager probably doesn't want to take that much power from the internal hardware. this is definitely a question that would be better served by google, however.
