I have two generic 4-port USB hubs that are supposed to be USB 2.0
compliant. The older one is fine, works as advertised. Meanwhile the
newer one sometimes shows up under the USB 2.0 root hub (i.e. "Standard
Enhanced PCI to USB Host Controller"), or usually it shows up under the
slower "Standard OpenHCD USB Host Controller" (USB 1.1).
My motherboard (Asus M2NPV-VM) USB ports are all USB 2.0 compliant, and
they individually auto-detect whether they need to switch down to USB
1.1 speeds. I'm using a Microsoft tool called UVCView under Windows XP
to display the details of the USB devices, including the hubs and roothubs.
According to UVCView, the older hub and newer hub seem to have the same
chipset vendor (idVendor = "Genesys Logic, Inc."), although externally
they look quite different and have different brand names. So I'm not
sure why one would be consistently USB 2.0 compliant, while the other
one is not.
Now another interesting thing I noticed is that the inconsistent hub
will only show up as USB 2.0-compliant after I boot into Windows after
having previously rebooted from Ubuntu 7.10 Linux (dual-boot system). So
maybe Linux does something to the device that puts it right. But when I
list the devices while in Linux I see that it is listed under USB 1.1
just like when in Windows. I have no idea why Linux leaves the hub fixed
for Windows, but doesn't fix it for itself?!
Any idea what's going on with this hub?

Well, that's not going to be likely to do. Since the newer hub is so
unreliable, I'm only trusting it with light duty at the moment, such as
mouse and keyboard connections, nothing data-heavy like external HDs, or
thumbdrives.

Depends on if by China, you mean both Taiwan and the PRC or just the PRC.
For that matter, since "made in" usually means final assembly, there are
probably some from Thailand and Malaysia too.

What you may want to do since you are running an Asus board, is go into
Bios setup on bootup before your OS loads. Under one of the tabs across
the top, there is a check for "I am using an OS that checks for plug and
play" or something like that. It may be that your Bios is not setting
the USB ports and allow only the operating system to do that. It sounds
as if Windows is setting the USB port/hubs and then you switch into
Linux. Anyway, might be worth a try. >> Stay informed about: Generic USB 2.0 hub showing up as USB 1.1 |

Yeah, moving the cables around throughout all of the USB ports was the
first thing I tried. The problem moves with the hub, not with the USB port.
I've even tried a different cable as suggested elsewhere in this thread.
It didn't help. However, as I said before, going into Linux and then
rebooting into Windows fixes it for some inexplicable reason. So far
this trick has worked 100% reliably.

Sounds like it is time to toss the flaky old USB hub and get an new
one for $7. >> Stay informed about: Generic USB 2.0 hub showing up as USB 1.1 |

Not true. I recently (within the past 6 months) acquired two of the same
model ASUS motherboards (P5NE-SLI). One was assembled in Taiwan, one was
assembed in China. >> Stay informed about: Generic USB 2.0 hub showing up as USB 1.1 |

I was thinking the same thing, but it sounded too simple.  I
found one model I liked (seven-ports, two on top) so bought a
spare, just in case. I can't even buy the wall wart that came with
it for $7.

There are usually price breaks for products after which the rise in
price is almost logarithmic. 4-port USB hubs are most common and
probably where you get the best price break per port. Of course,
popular branding will cost you.
A self-powered 4-port USB hub (which obviously includes the power
adapter) starts at $5 (and Iogear is an okay brand). A 7-port USB hub
(for a brand that I've heard of) runs about $20. It's just like CPUs:
you'll find a sweet price break afterwhich the jumps in price far
outstrips the meager increase in speed.
Sounds like you're trying to replace both USB hubs with one. >> Stay informed about: Generic USB 2.0 hub showing up as USB 1.1 |

However, many are bus-powered (which they misname as self-powered) or
require the addition of an "optional" power adapter (at further
expense, of course). I noticed the cheapest 4-port USB 2.0 hub in the
list that includes the power adapter is $11 (but I've never heard of
the Anywhere brand). The next one up is the Rosewill for a $1 more.
So the $5 and $7 models are those that are bus-powered or don't
include the power adapter, sorry. It's possible you could reuse the
old power adapter provided it supplied the correct voltage and also
could push out the required milliamps. >> Stay informed about: Generic USB 2.0 hub showing up as USB 1.1 |

I paid $7 for the hub *AND* wall wart. That's my point. I wasn't
near it when I posted earlier, but it's a Belkin.

How about "Belkin"? BTW, NewEgg is Charging $30 now for the silver
version:

Huh? I said nothing about replacing anything. I did mention that
I bought a spare (nice hub for what I paid, why not?).
