Review: First of all, this has to go in the top PC slot, because it is bulky.Second, I couldnt get it to work with my notebook (running ME). The lights stayed red. Most importantly, and the reason I didnt pursue trying to get it to work for too long, as a previous review said, the card interfered with my wireless connection. My wireless nic card below the usb adapter couldnt hold a signal, even without the usb card working. So, I returned it, needless to say.

Summary: Good Product ( required extra work)
Review: Here what I had to do to get the adapter to work:
- Go to the Adaptec Website, download the latest driver (Using the Model number on the adapter)
- Go to the Adaptec trouble shoot website and follow the instruction for work around to overwrite the WinXP SP2.
- Reboot then you will be fine.
I give it **** because of the above problem. Otherwise, it worked great with all my external devices( External Hard Drive, DVD burner ...etc)
Note: - Linux setup for this is a lot easier.
- Toshiba laptop may have lower voltage on the PCMCIA slot
so make sure to check it out.

Review: I bought this adapter to improve the data transfer rate to an external USB2 hard drive and as such it works quite well. Data transfer rate is 6 MB/s, about 10 times as fast as with USB1. Your mileage may vary. I use the card exclusively under Linux; a recent kernel (2.4.21 or 2.5.5*) is necessary to get it to work reliably using updated EHCI drivers.

Review: I bought this card for a Toshiba 6100 Satellite Pro. I intended it to work with a Maxtor USB 2.0 portable external hard drive which it does very well. One thing of interest - I found XP Pro with service pack 1 has a driver for it and there's no need to install Adaptec's. In fact, Adaptec's doesn't install successfully as per their instructions, I'm assuming because of XP service pack 1. No matter, Windows XP's driver works great and at USB 2 speed.

Review: I bought this device after buying a Buslink USB2.0 40GB hard drive and experiencing problems when running it through my USB1.1 hub - it was time to either upgrade the hub or make the move to USB2.0. The coin came down on the Adaptec card, mainly because of the speed increase USB2.0 delivers and because it woud give me 2 USB host ports in addition to the single hosr port on my laptop. The Adaptec card went in ok and installed easy enough - but immediately gave me the same problems I was having with the Buslink drive running through the USB1.1 hub. Not a good start, but it has a happy ending. I checked the Adaptec web site and downloaded new drivers(V2.2 at the time of writing, V1.1 shipped with the unit). I followed the very clear and simple instructions and a reboot later all was working fine. I've not thrashed the Buslink drive/Adaptec PC Card combination too hard yet, and it's only been going for a day or two, but so far so good. The Adaptec PC Card/Buslink drive works well and seems faster than the internal drive in my aging laptop (NEC Versa LX, 233MHz, 168 MB, Windows 2000 SP2) 4 stars because of the need to update the driver.

Summary: Excellent product
Review: I bought this item after a bad experience with an ADS Technologies card (see my review for that one) that did not work. At first I was hesitant to shell out the cash for the Adaptec, but I was so desperate to find a USB2.0 PCMCIA card that did NOT require an AC adapter.
I have an HP Pavilion ZT1180 notebook, running XP Home SP2. Older, but a great notebook. The biggest drawback of my notebook is the lack of USB 2.0 ports (they are all USB 1.1). I needed a card that I could use with my 802.11 SuperG usb dongle and did NOT require an AC adapter. What's the point of being wireless if you still have to plug in the card!
The card is basically Plug and Play. I popped it into my notebook and it was rarin' to go (after the usual XP prompts to detect drivers, etc). I did not need to run the included CD-ROM, nor did I need to go to the Adaptec website for updated drivers. XP Home SP2 had the drivers for it. The card was able to support and provide enough power for my wireless USB dongle like a pro and I was able to surf at 108 mbps! I am EXTREMELY pleased with this card. I have not pushed the card by trying to install another usb device that would require power. There is a jack for an AC adapter, but no adapter was included with the product. You could probably pick one up easily at a Target or Radio Shack if necessary.
I have to say that it is worth the price (hence 5 stars) because of the power issue. Similar cheaper no-name or generic brand cards aren't capable of providing enough juice to power a simple USB dongle.
