#1 Re: Questions and Requests » Wierd USB errors » 2009-02-16 22:06:22


Oddly enough this has happened with a couple boards I've seen so far. I am offering those who bought one a brand new board that I know works. Since then I've changed placement houses and the new place (here in Maryland) will flash the bootloader to the ARM for me and test the USB connection before I accept the boards back. The last place was a little shady, unfortunately I had to pay a ton for the tooling and they screwed up 2-3 of my boards. I'm going to trouble shoot the boards when they come back and figure out what happened, I have a few guesses as to the hardware component that has been troublesome. I will also take a look at where the bootloader is flashed in memory but I don't think that's the issue. the J-Link Segger tools are really good for memory/bootloader debugging (but stupid expensive.)

As always, shoot me an e-mail and I will take care of any problems.

d18, did you get your board from me? if not e-mail me: i'm back from traveling and can send ASAP if not. I've sent a bunch out already. smile

I was trying to cause this error, and I did so by unplugging the wiggler, (leaving the wiggler @ LPT1 port setting in ARMPRG) and then hitting reset&run. Having the wrong interface setting with the wrong cable would probably cause this.

Also, if I just leave the USB plugged-in and use the USB adapter setting in ARMPGM, I get a USB library error.

Anyone else get that?

Cool, I think I remember seeing something along this in the text documents written by JW. I'll take another look, I'm assuming when we erased the chip with ARMPGM, it would've removed that though?

I tried running ARMPGM and executing "RESET&RUN" and it errors "Unable to initialize USB Library". When I plug it in, it pops up with the "A USB device has malfunctioned" ... and if you go to troubleshoot it says there are no drivers installed for this device. I hate software >< (double E FTW) anyway, it seems obvious that it's a problem with the USB communication, I'm just not sure what is needed for the device for windows to recognize it, or well the batch scripts to recognize it as well.

One of my devices is being a giant cheese ball...

I flashed it correctly and used ARMPGM to verify everything, that process was smooth, then I downloaded the MIFARE source and tried running FlashOS.bat and all it does is pull up a cmd.exe window with:

"... no device connected, polling for it now."

I can't get it working at all but the flashing went smoothly so I'm confused.

Any idea what I could check?

Hi guys,

Just to let everyone know who is interested. This weekend I will be working on "How to design and build an antenna for the Proxmark 3 device" for this community. - I will be building a bunch of them for some clients so I can take pictures and write down all of the crazy RF equations that I love, hehe.

I will post it on the forums when it is done! If anyone wants to help, shoot me an e-mail !

I wanted to start a thread about getting the proxmark 3 to be able to attack the MIFARE standard, so I'm starting with the white paper released the digital security group: … sorics.pdf


#9 Re: Trade Parts » Ordering of new proxmarks » 2008-10-11 04:11:03


Hi guys, new here... I posted this on another thread but I might as well shoot it here too.

I have like 90 Proxmark3 PCBs, I've been getting 10-20 made and then selling them. I gave away A LOT of the pcb's to people I thought would benefit from them (which most of them have) and they contributed a lot back to the community.

I created an updated EXCEL list with all WORKING part numbers for the proxmark3. The first time I went to order these like 20% of the numbers were obsoleted by Digikey / Mouser / etc.

Presents for you:

Don't worry about all the colors and stuff, the info there is good. That's all you need. I ordered most things from Digikey and the rest from Mouser.

I am willing to help anyone out who has questions getting orders done, placement houses, PCB's made, soldering SMD 0603, programming / flashing whatever.

I will hopefully check this forum occasionally, if not e-mail me:


oh btw: my boards were made with black soldermask, they look so much sexier! hehe

#10 Re: Questions and Requests » Pre-built ProxmarkIII boards » 2008-10-11 00:32:22


Hi guys,

FYI: I actually bought about 100 proxmark3 PCBs and I've been ordering about 10-20 PM3 units at a time from the placement house. If you guys want a pre-built unit, working out of the box. I can even flash it for you, feel free to contact me. I don't mean to solicit by any means, and feel free to delete this e-mail if I've done something wrong but my website will be up eventually where you can buy them, until then e-mail me:
