I can only conclude that the hub is not providing adequate power for four 8G OCZ Rally2 flash devices.I have not had a problem with temperature. The devices seem to work well when four of them are used in a different four-port hub, but when used in this hub they occasionally have an I/O error. I purchased two of these a few months ago and have used them exclusively for eight flash memory devices made by OCZ. Io performance seems reasonable. Using the external power does not fix the problem. Since I own two of them and eight memory devices and it doesn't matter which combination I use them in, the problem is consistently associated with this hub. Form factor is great, but this doesn't matter so much if you have to carry the external AC adapter too. The USB dongle on one of my units gets stuck very easily, but this has improved with wear.
Keep up the great work guys/gals. I would definitely recommend this item as a good BUY, works well NO problems so far.
Received everything I ordered online through AMAZON.COM from the Seller 365USA in excellent condition and packed very securely and showing care for efficient delivery. Received the shipment Dec.
Ordered one of this item along with multiple others [I qualified for FREE shipping]. Items were as advertised and were in new condition still in original packaging.
17, 2009 via UPS so delivery was as expected, if not sooner. UPS drivers were hurried because of Christmas rush I'm sure.
Am a well-satisfied customer of AMAZON.COM at this point. MERRY CHRISTMAS AND A HAPPY, PROSPEROUS NEW YEAR 2010.
This was a great idea for a 4 port hup but it was it badly Designed. The cables were way to short. It seamed too hard to add more than two extra USB cables because the extra USB slots seemed too close to gether.Thats my two cents.
It is compact for convinience and seems to do a good job so far. I can connect it to my laptop and disconnect it at any moment and all of my peripherial still work properly once reconnected.The only thing is when I first got it, it made my computer crash a few times when my laptop went into hybernation over night after leaving it on and the screen up. I have started closing the screen at night and it isn't doing that any more.
I am now using it with a Dell Laptop and it seems to be doing fine. I bought two of the hubs in June 2004. The other one I used with a Mac for about a year and a half now and it has failed. One of them failed in about a month of using it with a HP/Compaq Laptop. IOGEAR replaced it for me. I am beyond warranty so I will go with a different hub to replace it. It does run hot so I think it must have good ventilation to hold up well.
