USB 1.1 with 802.11g

Anyone know how much slower an 802.11g USB adapter is when hooked to a
USB 1.1 port? Will it operate at "b" speeds or closer to 'g' speeds?

USB 1.1 port max rate is 11mbps. G is max 54 Mbps.

Only at 11b speed. Since USB 1.1 only supports 12Mbps data transfer rate,
while
2.0 up to 480Mbps, far more than 11g's 54Mbps.

Anyone know an easy way to determine whether or not a pc has a 2.0 USB
port/hub?

Two ways:
I have a cheap (free after rebate) 1.1 hub, and a 2.0 flash drive.
If I plug the flash into the hub into a 2.0 port, I get a complaint from
WinXP that I have a less-than-optimum arrangement.

start-settings-control panel-system-hardware-device manager
Click on +Universal Serial Bus Controllers.
If Enhanced appears, you have 2.0.
"Intel PCI to USB Enhanced Host Controller"
Standard is 1.1, which also appears under any 2.0 controller by spec.
"Standard Universal PCI to USB Host Controller"
My Dell also shows "USB 2.0 root hub" which is fairly obvious, but that
only appears on some machines (with multiple USB ports).

If it were easy, it would be no fun.

1. Read the data sheet on the PC manufacturers web pile.
2. Dive into the Windoze Control panel -> System -> Hardware(?) and
see if there's a USB 2.0 port listed.
3. Plug in a USB 2.0 device and watch Windoze complain with a message
that it can only find a USB 1.1 device. This varies with drivers.
4. Download and run one of the free system information tools.

In Control panel -> System -> Devices, if there is a USB 2.0 there will be
entries for standard USB and an additional entry for USB 2.0 or Enhanced
USB.

Jeff -

I have the AIDA32 utility and it could not tell me what kind of USB adapter
my Dell DImension 4400 had. Are you sure it and the other one will? If so,
exactly where do I look in the results?

I eventually used the AIDA32 info on motherboard to go to the Intel site and
look up the specs for my motherboard.

So "Standard Enhanced PCI to USB Host Controller" means I have a USB 2.0
port? THat's what the Belarc tool reports to me.

AIDA32 version 3.93.
1. Devices -> Windoze Devices -> USB 2.0 Root Hub
2. Devices -> Physical Devices -> PCI Devices -> NEC USB Enhanced
Host Controller.

Yep. That also works.
