USB Hub Wierdness

        Hey guys, I think your both right on this one.

        2600 you know your USB inside and out and I learned a couple of things from you, thanks, but I have a problem with any thing that's surposed to be backward compatatble. I've seen alot of devices that were surposed to be backward compatatble and weren't. It depends on hardware, software, manufacturer and what setup you have. USB is processor intensive by way of IRQ's and in the case of CP's there is gonna be small amount of lag anyway with mouse and keyboards both vying for processor time.

        This is just my personal approach to the problem... I would disable USB2 in the Bios, exchange the USB2 card for the USB1.1 card and try that. My reasoning is that now everytning is USB1.1 compatable. The only other thing to try is to check for updated drivers for your USB2 Hub.

        I love this place, there is so much you can learn by reading the posts.

I'm sure you're right...I hadn't even considered a problem running a USB1.1 device off of a USB2 hub to be honest.  I guess there is a mismatch there somewhere...

Hmm but then I can't use my HDD at USB2 speed (which is a must for rom transfers etc.).  The USB2 hub seems to work perfectly with USB2 disabled anyway...I hadn't checked for new drivers, but I will do that now :)

photorock:

       I didn't realize you had any USB2 devices (HD), that's a different story. If you want to keep those HD transfer rates up you will need USB2 support for that. That makes it a little easier, I would enable USB2 in the Bios and check for updated drivers for your hub first, If you find none then exchange the USB2 Hub for a USB1.1 Hub. Then when you first plug it in Windows will recoginize it as a USB1.1 Hub and load the proper drivers for it.

      It should work properly then. The only thing is I have never used any USB2 devices so I don't know if there are any little qwerks involved with USB2. 2600 is an expert on that. I hope this helps.

Minwah,
Theres a couple of things you could do, but it's all about what you prefer.
Also, photrock is right about updating drivers, but I don't believe MS has released any updated drivers, plus hubs don't have "drivers" per se, they just use the standard driver that comes with the USB stack.  What you could look at is making sure you installed your chipset software depending on your Motherboard.  What kind do you have, btw?   Also, you didn't mention what OS you are using, but I doubt you reallly want to update that anyways.

Here's a couple of notes and suggested solutions:
A: You really shouldn't use a hub for your controls.  It adds a bit of delay, BUT it is convienent.
B: You could try a different hub, maybe you did get a bad one or they are using a crappy chip.  But really there pretty much the same.  If you get a different one, get a different brand and don't worry about price, money doesn't really buy you anything.
C: You are only using your USB Hard drive for updates, Right?  Well enable USB 2 when you update the roms and disable when you don't need it.  I think there's a couple of ways you could do this.
   1. The BIOS way I showed you.
   2. Then in Windows I think there is a couple of ways you could do it.  In the Windows way, you don't touch your BIOS you just leave it enabled.  I think you can create different hardware profiles and then at boot up you select which one you want.  So in one you would have it enabled, and then in the other you would disable it in Device Manager and save that profile. Or you could just enable it in Device Manager when you want to use it.  Oh, and What you are enabling/disabling in Device Manager is the EHCI controller(Enhanced Host Controller Interface).

Either way it's up to you for your situation.   Try them and see which you like the best.

Is the primary reason for the new hub that you can't access your USB ports?

If so, you might try running the controls on the old hub, and leave the new hub dedicated to connecting the HD.
