don't worry about the TVS diode, it is just an optional component
you may need a heatsink for 7805
and the 12v/1a may NOT be enough for you
I use a 5v 2a power because I know I only need to power a 5v/100ma flash drive
but two usb port may drain up to 5v/1a
so please make sure you are not overloading the power
and don't worry about the wattage of resistors

It looks like in addition to the heat sink I would also need to add a couple of capacitors to the 5v power circuit if I go with the regulator. If I were to go that route could I just run a 2 or 3 amp 12v supply instead of the 1 amp supply and be okay or would it just be better all around to run a second external 5v supply like you are doing? Here's an example of the 5v supply with the capacitors:
either way will work
just make sure the voltage is regulated
and nothing is overloaded
Bummer, no go so far. I did a mock up on a breadboard drawing 12v from the WRT and stepping it down with a 7805 circuit. The power seems to work fine but I don't think the USB circuit is working. At least it's not detecting my 1GB cruzer thumb drive. It's a 2.0 drive but supposed to be compatible with 1.1. I did install the USB kernel modules and libraries and they are loaded. I plug the thumb drive in and it lights up for a second then goes out. Nothing in dmesg. I tried swapping D+ and D- and made no difference. I did pick up a separate 12v to 5v module already built. Maybe I'll try running that instead of drawing power from the WRT in case there is not enough power. The WRT runs fine though with or without the thumb drive plugged in. Again, I'm an electronics n00b so maybe my breadboard configuration is wrong. Here are some pics:

something you should try:
1.take away these 15k resistor
2.remove the original "472" resistor and put these 15k resistor back
3.flash your router to dd-wrt 13064+ and load only the OHCI driver (unless you are sure that currently your USB kernel modules and libraries are properly loaded)
4. do not use bread board for the usb signal lines
5.you may need to connect ground closer to bcm5352
ps. each of these is a independent suggestion

Crap, it works! 
I'm not sure exactly what the problem was as it's currently working under the exact same setup as in the pictures. On the way out the door to work this morning I decided to try a few things. You did tip me off to one thing that would have caused it to never work. I didn't have the ohci kernel module installed, however after installing it and it detecting the ports it still didn't detect any device plugged into the USB ports, even after rebooting the router. So, I disconnected the 15k resisters, still nothing. Swapped the data lines, still nothing. Tried the other power source with a second power supply, still nothing.
So, I put everything back the way I started and power cycled everything. I logged in to the serial console and looked around and happened to look down and saw the thumb drive light was on steady. That was different. Looked at the dmesg output and it showed my mass storage. Installed vfat module (wasn't sure what I had on the stick and didn't want to reformat yet) and mounted the device with no problem. So now it's just put everything onto a permanent board and mount it.
Thanks for all your help on this!
Oh, this is Kamikaze 8.09.2 (2.4 kernel).
Hi, glad you got the bastard to play nice Void Man. Can you replicate this error with your setup when overclocking or underclocking?
The device no longer likes either overclocking or underclocking when the usb is plugged. I am thinking the bus itself is sensitive, thinking back agp or pci clock tempermentality prior to locks. I am neither using a regulator or additional resistors, just an adapter 5v @~1750ma. I've successfully run 3 devices off the unit (bcm5352) with an unpowered hub. The supply seems to be and should be more than ample wattage for 2 usb spec devices and the router, but acts funky when I change the clock frequency, something I didn't experience before.

Well, my numbers are about the same as yours on my WRT54GSv3 as far as speed:
# hdparm -tT /dev/scsi/host0/bus0/target0/lun0/disc
/dev/scsi/host0/bus0/target0/lun0/disc:
Timing cached reads: 2 MB in 2.22 seconds = 922.52 kB/sec
Timing buffered disk reads: 4 MB in 4.47 seconds = 916.33 kB/secBut not as bad as my SD card (MMC) on my WRT54Gv2.2:
# hdparm -tT /dev/mmc/disc0/disc
/dev/mmc/disc0/disc:
Timing cached reads: 2 MB in 5.86 seconds = 349.49 kB/sec
Timing buffered disk reads: 2 MB in 5.56 seconds = 368.35 kB/secI'll try overclocking this evening. Also remember this is only USB 1.1 which has a maximum of 12mbps (1,536 kB/sec), so we are getting over half of the maximum possible which isn't bad in my opinion.
thanks man, much appreciation!
Actually, both usb 1.0 and 2.0 exist on the chip...given your -t result, you must be on the 1.1 channel so your router may be unaffected by the clock alteration, maybe. The prior page has my router's solder points. I used the 2.0 channel.
root@fscd@#$g54t:~# hdparm -tT /dev/scsi/host0/bus0/target0/lun0/disc
Timing cached reads: 116 MB in 2.00 seconds = 58.00 MB/sec
Timing buffered disk reads: 4 MB in 4.70 seconds = 871.49 kB/secAre you using the new mmc driver? With the sdhc driver, I consistently get no less than 400kB/s.

I haven't done any overclocking (never saw the need), I was going to test that for you tonight. Regarding your SD driver what OS are you running. I'm running Kamikaze 8.09.2 kernel 2.4. Is that what that module is for? The WRT54GSv3 has USB 2.0? I only see 1.1:

I guess I have usb 1 and the soldering points are as in bus 1/2. I didn't notice ehci wasn't loaded... oops....

What is the source of that mmc module? Is it already included in the kernel? Is it GPL? I'm not going to run it without knowing where it comes from. Regarding your mention of your usb2 success. I see where you posted a link earlier in this thread to another thread and you mention usb2 but you don't mention what it is that makes you believe you have usb2. It would be really nice if I could get usb2 but what I have read from zerx and from what I see on my router it's only v1.1.
If you read what I posted, you would know where it came from. Alternatively, it is in the module itself
"description=MMHC/SDHC Card Block Driver - 2.0.1"
"author=madsuk/Rohde/Cyril CATTIAUX/Marc DENTY/rcichielo KRUSCH/Chris"
"license=GPL"
More than enough to go on if you really wanted find the source and compile it yourself...

I soldered up a board and started a HOWTO:
http://voidmain.is-a-geek.net/wrt/wrt_usb_mod.html
It's all pictures for now but I'm tired and going to bed. Everything worked pretty well until the wires soldered to usb2 on the WRT board came loose and I couldn't get them to stick again. Down to one USB port now. I used a 10 pin serial header so it can be connected/disconnected.
Hi Zerx,
I have a wrt54gs v1.0 (CGN1 serial)
So you say for usb 2, need pins rh21 and rh22... I found them.
But where do you get the 5v and GND? Or did you mean that you had to get it externally?
Thanks,
Robert

Never mind, I figured out that you meant running a 5v adapter instead of the stock 9v one. Got it sorted out...
However speeds are slow... router to pc 660KB/sec. PC to router 800KB/sec using SAMBA, ftp on a flash OR external HDD.
I wonder how to get USB 2.0 working, is that even possible on broadcom 4712?
re all,
anyone tried usb mod on Broadcom 4716 and/or 4704? in particular i'm interested in moding WRT 160N.
regards,
WRT54G v1.0 - maybe? (other non-linksys routers with Broadcom 4710 have usb)
WRT54G v1.1 - maybe? (other non-linksys routers with Broadcom 4710 have usb)
WRT54G v2.0 - YES (http://woodhousellc.com/?tag=usb) (also I have managed it)
WRT54G v2.2 - probably (same BCM4712 as v2.0)
WRT54G v3.0 - probably (same BCM4712 as v2.0)
WRT54G v3.1 - probably (same BCM4712 as v2.0)
WRT54G v4.0 - probably (same BCM5352 as wrt54gs v3.0)
WRT54G v4+ - no
WRT54GL v* - probably (same BCM5352 as wrt54gs v3.0)
WRTP54G v* - no?
WRT54GS v3.0 - YES (http://voidmain.is-a-geek.net/wrt/wrt_usb_mod.html)
WRTSL54GS v* - no?
am I corrent? if not say, and I will maintain this preliminary list.

looking for a dual wan solution, does anyone have any experience with converting a dd-wrt / tomato router into a dual wan ..

Does this work for connecting USB 3g modems?
I would not see a reason against it (unless it draws more power than the router can deliver - seems to be an issue for some routers, using an active powered hub helps in that case).
Hi,
I have a WRT54g V3.1 and am trying to look for these usb pins on my modem.
The 4712 chip is positionned exactly like this one http://i708.photobucket.com/albums/ww82/jbryantd/photo11.jpg (not my image, but probably same version of router).
Is there any hint to pinhunt ? I tested RH10 ot 16 with an oscilloscope and the voltage is either 0 either 3.3V but nothing like a signal.
How can I find out where I can pick up my USB signal ?
The discussion might have continued from here.
