USB hub causes other USB ports to fail
-
Hi, I'm using Windows 7 Ultimate (64 bit). I have a new USB hub that is causing some problems. If the PC boots up with the hub attached then the hub isn't recognized and some of the built in ports don't work (these ports have an external hard drive and a wireless network adapter plugged in). Some of the built in ports do work (these ports have the mouse and keyboard plugged in). If the PC boots up without the hub attached then all of the built in ports work fine. If I then plug in the hub all the devices plugged into it work fine. Any ideas what I can do to make the PC boot up and have all built in ports and all ports on the hub work correctly? Thanks, dlarkin77

Out of interest what are the error codes in device manager fo rthe failing hubs? Do you know if the hub causes the same behaviour on XP? Can you identify the driver associated with the hub? If so you could force it to start later, set its start type to 3 in the services\ key. If you dont need USB boot capabilities then you could try moving it down the list in the BIOS, this might help. Generlaly though this kind of thing is fairly typical of USB on post XP oses. Microsoft really messed around with the USB subsys on Vista, it caused a hell of a lot of problems which got carried over into 7. Previously working HW would fail, behave erratically, all sorts of stuff.
