Summary: After trying lesser (meaning cheaper) cards, I tried this one. It works GREAT! Only thing I would add would be to package it with an external power source which is needed to operate most attached hard drives.
Summary: this IOGEAR cardbus totally saved me in a pinch. my usb ports fried on my laptop. i had no way to get info off laptop other than to email them. this saved me and i am able to get info off laptop to an external harddrive.
Summary: This works fine on a Mac Powerbook G4. The hitch is that you need the extra power supply if you are using a device that is supplied a large amount of power from the USB port. For example, a USB disk drive, such as a GO drive, needs the external power supply. If you plug in a device that draws a lot of power, it will lock up your machine and you will have to reboot. The power supply is OADB-0705-261G. You can ask IOGear about this.
Summary: Be sure you have reflected significantly before purchasing this product. The only things that I can use it for are my flash disks. And it speeds up the data transfer. For anything else, you MUST have the power adapter (which does not come with the cardbus). Even with the power adapter, this bus would not support a printer. Otherwise, it works fine.
Summary: Great product! The quality is superb, and, I believe people only complain that it doesn't work because the device can only provide so much phantom power to your peripherals. However, it does function with devices requiring less power, like a wireless keyboard/mouse combination or an externally powered ext. hard drive. Both work flawlessly! It does protrude a bit, but that's pretty expected.
Summary: Some of the comments have information that is not accurate, stated as if it applies to all machines with Intel chipsets. I'm running Win'XP w/SP3. IBM ThinkPad T40 with an Intel 82801 chipset. The IOGEAR installed fine and is working with a Seagate 500GB USB2 drive, with absolutely no issues. Hope that helps others considering this device.
Summary: First off, it's bulky so it won't fit in my dual PCMIA slot if I am using another PCMIA card at the same time. Second, if you are going to use this device with an iPod, you need to buy the power cord (not included) for this device. Otherwise, it does not provide enough power to interact with your iPod.
Summary: I bought the IOGEAR Cardbus for my Dell Inspiron 8100 computer (three-plus years old) because the computer's USBs were all kaput. This product works flawlessly; I've had no problems, and my Dell is working like a champ. (Or at least it's working as well as it ever could.) I highly recommend this product.
Summary: I didn't see any reviews here that addressed Mac compatibility, so I thought I'd toss my hat in the ring.... Prior to OS X 10.2.8, the GPU202 worked, but only at USB 1.1 speeds. Not very helpful, since I already have built-in USB 1.1 ports on my TiBook 400. I then installed the drivers for this device, and got mixed results.
