Is it possible to mod the Netgear WNR2000v2 to add either a USB port internally (just wired with jumpers to the mainboard), or is there a way to wire an SD card to the mainboard so that storage can be used by ddwrt??

it has a bcm4716 which according to datasheets includes a usb2.0 host. whether or not the pins on the chip are connected to traces on the board are unknown unless someone here has done it. you could always pull up the datasheet and see if you can find the pins yourself and see if any traces lead back to them, though its difficult when it is a bga chip.
as for the mmc/sd card, you could manually toggle on/off gpio's and use a multimeter to test various points on the board. all you need is 3 free gpio's and you can run an sd card in spi mode.
the one problem with that is that it runs the 2.6 kernel, which unless something changed recently, does not support the mmc/sd driver in 2.6 - i believe there was a project on openwrt to get it to work though. _________________ TP-Link TL-WR1043ND - DD-WRT std BS build 20675

Thanks for taking the time to answer! Awesome. I learned something, even if it's not possible. I appreciate your answer. Much better than the rtfm/google it responses i get sometimes.
block diagram would indicate the 4716 probably doesnt even have the pinouts for the usb host. notice there are less bga pins on the chip. i still think the SoC has the host internally though. you can load usbcore and ehci-hcd modules and see if it recognizes it in software, but again its most likely a fruitless effort
if youre looking for additional storage, sd card would be your best bet there. its fairly easy to wire on in, provided you have the gpio's available. if youre on 2.6 kernel though, you'd have to switch to openwrt as dd-wrt and tomato (last i checked) dont have mmc/sd over gpio in 2.6 _________________ TP-Link TL-WR1043ND - DD-WRT std BS build 20675

yes looking for more storage plus feeling kind of do it yourself ish...
can't seem to get cifs to work, so I was looking at other alternatives...
plus I solder well, and am not afraid to take anything apart and modify it... as long as I have some idea of what to do or how to find out work any confidence what to do...
if soldering an SD card in is the simplest way, I'd rather so that... was mostly looking for ways to add software to ddwrt... like tcpdump and a few other strangely missing tools...
finally got tired of trying different combinations and permutations of syntax for what to put in the cifs fields. Couldn't find any site where they have a REAL example of the expected syntax beyond someone saying, "put in the correct values for your share"
and the "documentation" is pretty confusing. is not even clear whether samba, and cifs are even truly synonymous... yet when I search the wiki or manual or seems to imply they are... can't get it to mount a samba share from either of my os x machine, or my Ubuntu machines... yet from the os x, and Ubuntu machines, they can see each other, and mint reach other's samba shares. yet it seems I can never get ddwrt to see /mount the shares of those machines. it's so bizarre that i can't find actual spelled out example syntax on the Web.
