Squeezing in a hub and two USB Ports...Done

Hi All,

I was thinking for sometime since I got this little beauty to squeeze a hub into my EEE in order to obtain easy to reach, 4 USB ports internally . For the time being I used two of them for plugging in USB gadgets  and spared the other two for future mods like usb zigbee transceiver and an internal USB GPS Receiver.I have 8GB USB Flash and Belkin Bluetooth slotted in as seen in pix.I would like to thank, Tnkgrl,Tristand and Johnx for their useful info on connection points and ideas as well as to this great forum.

I like what you have done very much, any chance of some closeup pics of the connections, and which hub do you recommend?

Thanks.I used the synapsis flexible hub. Here is the link. http://synapsis.manufacturer.globalsour … SB-Hub.htm

I found it at Maplin for 16 Euros.The good thing about this hub is it has a very small foot print pcb and all USB ports are soldered via cables not directly on to pcb itself which saved me from desoldering the USB's from PCB.Also used the USB ports as they had their own wiring as seen in pix. You can get the connection points from this thread: http://forum.eeeuser.com/viewtopic.php?id=2334

Thanks Johnx.It will be really hard to crack the case open for an exact measurement but I can say that lengthwise it is half the ram module and width wise the same as ram module width.I measured and compared it with the ram module before I installed in just to see if I can put it under the Ram module but it was a bit thick to fit there as there was a cap and xtal which I needed to desolder so I gave up that idea.I hope this will be helpful.

Re: Squeezing in a hub and two USB Ports...Done

@Johnx,This hub is amazingly ideal for EEE mods.I was so lazy to desolder all USB ports from the hub pcb I almost gave up the idea of fitting in a hub and was going to your brilliant idea of sticking two ports in and solder them to mobo usb points,then I saw this in maplin last sat and fell in love@first sight!smile

How about using the same EEE and push the USB conns to hub's two ports and use the 3rd one extended  to the LCD bezel thru the hinges and plant a bluetooth in there!I am planning the bezel bluetooth mod this weekend.

Re: Squeezing in a hub and two USB Ports...Done

Indeed, I want the hub and bluetooth in the screen space using the camera USB connection to run the HUB then connecting USB 1 to camera, USB to bluetooth and running 3 & 4 down to the spare bay for 2 * 16GB flash voyagers.

Managed to get hold of a white Eee PC about 15 min ago, at least this way I can see what a white keyboard looks like on the black Eee PC smile

Re: Squeezing in a hub and two USB Ports...Done

Hi guys...I'm getting an EEE in a week or 2...I've seen all this mods and I'm really liking them...but I have a question...Why do you connect the 4 cables that go to the usb hub on diferent points of the motherboard, instead of just to one of the already available usb ports? thanks

There are two usb ports other than 3 external ones in the mini pcie conns, one in the wifi conn and the other one is in the ram bay.By using those the external ones are spared.If you don't mind losing one external port you can use it equally well and I think soldering to one of those will be more easy.it's a matter of choice i think.

Hey great mod big_smile .. if i ever get an EEE which im seriously considering .. well hoping i will do this mod. Here a link for the smae hub for $6.81 or about £3.40 for us english folk .. that includes free worldwide shipping, great site for memory and other cool stuff at great prices.

I just realized that your hub is at the same place as mine, great work!

Here is my hub mod + 2 x 16GB sticks: http://eeemod.net/forum/viewthread.php? … a=page%3D1 , sorry in foreign language.

But I put my sticks at MDC area because I want to save the Mini-PCIe area for SSD expansion.

Re: Squeezing in a hub and two USB Ports...Done

For anyone who wants to take this one step further, check out these two chips from TI:
TUSB2036 - 2/3 port USB hub (http://focus.ti.com/docs/prod/folders/p … b2036.html)
TUSB2046B - 4 port USB hub (http://focus.ti.com/docs/prod/folders/p … 2046b.html)

Either of these would be great for building you own hub from scratch (and you can get free samples of either chip, mine are coming in a week). Personally, I'm going to take this hack one step further and make my own mini PCIe card with the hub  chip hooked up to the USB pins, and headers for hooking up devices. I'll post again when I get it done.

Wow,what a clean approach to the same problem!I feel that mine needs a lot of house cleaning when I look at yours! smile and thanks for the great idea of  where to put my bluetooth,I was thinking to use one of the spare ports on hub and ditch it into the LCD bezel area but it is more easy to stick that near the modem port I suppose and I will end up with an empty USB port to slot in another 8Gig flash smile I was thinking to slot in two 16 gig flash but I thought I might buy another EEE with the investment on them so decided to wait till the price tag drops.

This is an impressive idea to have your own mini pcie card to slot in for usb hub and mods.Anyway I can't do that as Asus wasn't so generous to put in a mini pcie on my EEE!sad

Re: Squeezing in a hub and two USB Ports...Done

I installed the bluetooth dongle inside the EEE in order to free the mini pcie bay USB ports for more USB flash to gain storage.I used the third port of hub for bluetooth and the other two stayed as they are connected to USB receptacles. In order to improve signal strength of BT I cut out the aluminum shielding inside the cover just over the BT and that made a huge difference in signal strength. I still have one more USB left over in the hub and thinking to add a SirfstarIII patch antenna GPS module inside the LCD bezel! I would like to thank ckegg for showing me the available area for the bluetooth by adding the link for his mod.

so here is the outcome,

The bluetooth dongle fixed in it's place:

BT connection to the hub:

I wonder what the inside of this HUB looks like: It's foldable and it would absolutely rock if that first part of the hub would hold the PCB with all critical parts on it....who's gonna give it a try?

For those who are planning to do this mod, www.zipzoomfly.com is currently selling the Corsair 16GB Flash Voyager for $79.99 AR (99.99 less 20 MIR).  I never bought from them, don't know their reliability.

Most likely, the PCB w/ the hub chip is in the first bay, and the ports are just on a flexible wire (I don't think the thing bends back on itself like those old toys). I've also seen those on eBay for like half the price (I can't find a link now).

Watch out, that expires on the 14th, so you better buy now if you want to get the rebate.

And speaking of cheap 16GB flash drives, check out this guy on eBay:
http://search.ebay.com/_W0QQsassZbigbeno7
He has a ton of close out 16GB flash drives for $49 w/ free shipping. I plan on buying one or two myself later.
