Thanks very much for the reply. One more question: is it possible to export xpub from the device so you can generate receiving addresses without having the device plugged in? What I mean is using it with mycelium or BTCRecieve for watch only but also for generating receiving addresses.

yes, it's possible. It's not widely used so far, but you can find some examples in https://github.com/BitMEX/btchip-signing-tools for example.

Integration into Mycelium is also ongoing

Can I use greenbits on android to do all that is needed in wallet mode with the hw-1? I mean from initialization through usage? Or do I need to use a computer for some steps?

You'll need to use a computer for initialization.

Quote from: WBF1

Also, does hw-1 use it's own rng? Or does it use that of the host? Or some combination? Is it possible to add your own salt?

It uses its own RNG, or a seed provided by the user. After that, the RNG is not used if using deterministic signatures. It's not possible to add your own salt.

Quote from: WBF1

Also is the 2fa via usb keyboard emulation required for every transaction or is that optional?

It is required for every transaction - with the latest Ledger Wallet firmware, you can replace it by a security card lookup or a mobile second factor though.

Quote from: WBF1

Is hw-1 basically the same as ledger with a different form factor? Or are there usability differences?

It's the same chip in a different form factor - with the latest firmware, both are exactly similar features wise.

(sorry if these are answered elsewhere in this thread... I read back several pages and didn't see anything conclusive).

It would be awesome if there was a piece of software that anyone could use to turn a normal USB drive into a hardware wallet. But until then, this will do very nice to secure me Grin

Are these things still being shipped? I put an order through on hardwarewallet.com and it never accepted my payment =( ... I sent the BTC and it confirmed and I confirmed the addresses were the same. I never received an email or anything. I emailed hardwarewallet bout it ...
Anyone got ideas?

If everything goes through correctly, the payment page transforms in to a PDF confirmation receipt.

One of my orders failed to progress normally, so I emailed support and they sorted it out.

You could potentially also login to you payment history if the wallet you paid through supports BitID (probably only mycelium on android)

How long ago did you buy? When I bought mine there is no confirmation or contact after paying. They just mail it out and you receive it by regular airmail or registered airmail depending on the country you live in.

the card is supposed to appear as a usb device on 2581:2b7c on your system (using windows control panel / lsusb on Linux)

if it doesn't, check that you folded it properly

if it still doesn't work, contact support to get another one sent

ok, thanks. i guess mine must be dead - I accidentally broke it off on the "clip" before reading the full instructions, but it's stuck back on there just fine so i'm not sure if that is the issue, i wouldn't think so, it fits fairly snug etc.

i'll have a super-geek i work with give a try tomorrow before contacting support, maybe i'm missing something simple.

Thanks again, i appreciate the quick response.

yes, might just be slightly off - try to nudge it a bit up in the USB port maybe.

In Windows Device Manager it will show up as an HID (Human Interface Device). The computer sees it as a keyboard. It will not show up under the USB tab.

There is an option for using security keys when trying to log in to Google.

https://support.google.com/accounts/answer/6103523?hl=en

Is it possible to use the HW.1 key to secure my Google account while also using it to secure my Bitcoin wallet?

no, it's unfortunately not possible. The U2F implementation is done on a different firmware version requiring attestation keys that are installed at factory personalization time

Seems like a good project, keep it up and I hope these smart cards can get made!

well the cards are made and actually quite popular at TNABC

I got one yesterday in the mail. can't get any computer to even recognize it. how do i tell if it's dead or something? spent like 2 hours with it, waste of time so far... Sad

Edit - two windows 7 64-bit - even tried old drivers etc. nothing seems to work ... Windows device manager sees nothing at all, no matter what usb port i try. 1 Dell laptop and 1 ASUS home built desktop.

ps i tried on linux mint as well, but i didn't get very far at all before giving up there too. (Older laptop).

thanks for any help.

FYI it'll be possible to use the Ledger Wallet interface with HW.1 and the next firmware release with some additional setup. It'll also be possible to buy our next hardware wallets with a discount if you own a HW.1 or a Ledger Wallet.

Did you try to remove it and reinstall it ? It looks like a filesystem corruption.
