WL500g with 2 usb ports

[Technik]

nice post Technik!

I've been so busy that I haven't has the time to check this out...
I remembered to check the forum today, and was glad to find that someone has a solution.

[Technik], please confirm that this is the correct shematic:

                ___    ____
             o-|N1 |--|GND \_
USB2      R1 o-|P1 |--|    __
pin3  --/\/\/--|P2 |--|   /
pin2  --/\/\/--|N2 |--|__/
          R2    ---
               RN28
pin 1 -- +5v
pin 4 -- gnd)


(R1=R2=15ohm)

(usb pinout: http://www.interfacebus.com/Design_Connector_USB.html#b )

Also, did you use external 15ohm resistors, or did you "reuse" the free RN2 15 Ohm resistances on the board?
where did you get the +5v from? (which part of the pcb?)
I guess a capacitor next to the +5v input of pin1 would be a nice addon, don't you think?

regards,

Thanks!
I can confirm that your schematic diagram is OK.
As soldering on small onboard SMD parts is a bit difficult, I prefer using external resistors.
I am getting 5V from the input connector as marked, not directly but through additional reversible 0.7A fuse (PolySwitch).
In case you need a high power for external HDD, I would use some additional serial coils on both 5V and GND (taken from the power input connector) and ~1.2A fuse.

Hi.

I've been out for some time and only today I've had the time to check this fantastic discover .

As I have two USB disk's and with a USB hub I can't put them to work as I want this is the perfect soluction for my case but unfortunately I'm not a expert in electronics so, can someone post some more detailed info about this, with photos and all that so that I can also put a second USB port on my router?

Thanks,
Miguel

Please don't try to do it if the info above is not sufficient for you. Onboard parts that you need to solder on are quite small and without some experiences you may permanently damage the router. Also warranty is void as soon as you remove the warranty label covering one screw...

Thanks for the advice.

In fact I don't understand the info posted here maybe if it was in portuguese ... Now the solder and warranty are not a problem as I have a friend with solder experience and warranty was gone long time ago.

OK then... So this is a (perhaps) more clear "how to".
Router board version needs to be 2.xx as older boards have a different layout.
Good luck!

Thanks for the answer. Yes this is a more clear "how to" .

Just one last question. In the resistors you mention 15 Ohm, the fuse of 1 amp but what about the coil (ferrite slug) resistance ?

Thanks,

You can use almost any coil type, it's not a critical part - the reason is to eliminate interference. D.C. resistance of the coil should be max. 0.1 Ohm.

Hi, I really like this idea.
But when I checked photos,
on the Board.jpg you can see BCM4702KBP (the same I have got as well),
on the Detail1.jpg you can see BCM4333KBP.
I do not have detailed BCM4702KBP description.
My question is - has anybody checked this modification with BCM4702KBP?
PCB seems to be the same as in the photos.

Thank you,

Jiri

Hi,

i just wanted to confirm that i was able to successfully connect a USB memory stick to the internal USB port.

Thank you for the good work!

Note:
I had to change D+ and D- correspondig to the green labels B and C on the the screen shot here in this thread.

The black labels "P" and "N" on the other screen shot are correct.

Hi
this is great im gonna build in a small hdd

do i need all these resistors and coils when i put there usb IDE for hdd ?

also what are that unused pins on the left of the board, labeled JD1 ?
