hw.1 support

[molecular]

I'm trying to get my old hw.1 to work in electrum. samples/getFirmwareVersion.py doesn't see the device (matching udev rule is in place).

I see in btchipComm.py the usb id of the hw.1 (2581:1b7c) isn't recognized?

Was hw.1 support dropped? I remember using it sucessfully years ago with electrum.

WinUSB communication support has been dropped - you can update the firmware to a more recent version and keep using it with Electrum

[molecular]

cool.

I fail to update the firmware though. This page: https://firmwareupdate.hardwarewallet.com/ says I should enter the PIN 3 times. How can I enter the PIN when no software I have will recognize the device?

I clicked "start update" anyway, but the site says: "Please connect your BTChip dongle"

re-plugging doesn't help.

what else can I check / do?

Can you try to reflash using the Ledger Wallet Bitcoin Chrome application ?

[molecular]

Thanks for that pointer!

It looks better but still no success. It seems to find the device (yay!) and says "Verifying authenticity of your ledger wallet...." now for about 10 minutes.

Trying on a different machine... looks the same.

Maybe the device is in some weird state? I hadn't used it for years and I'm not sure what were the last actions I did.

[btchip]

Try to remove it and try again. After some time (I think 1-2 minutes) it should timeout and prompt you to reflash, then this should work.

[molecular]

unplugged hw.1, restarted chrome, started the extension (it says: please plug in your ledger), I plug it in (directly into the port, no usb hub this time). It's recognized quickly, page says "verifying authenticity..." Waiting now, but I don't think a timeout will happen due to previous experience.

[btchip]

ok, I'll recheck - might take a couple weeks

[molecular]

ok... background: I'm trying to help people with electron-cash wallet + ledger. I know you're not a fan, but I'm happy you support cash anyway in your hardware. Thanks for that!

[btchip]

oh in that case you can PM me an address on reddit and I'll send a few, should be faster

[molecular]

@btchip I PMed an address on reddit. Did you receive that PM? Just asking because otherwise I'll just buy a device.

[btchip]

Sorry I've been traveling lately. Should get it shipped today

[molecular]

received the btchips. Thanks a ton! Will share them with other electron-devs who they could be useful to.

[btchip]

great. Note that you'll need to flash them to the latest firmware using our Bitcoin Chrome app before they can be used

[molecular]

hmmm, updating firmware worked to a point (it is at least uploaded to the device) using "Ledger Wallet Bitcoin" chrome app. But now the app wants me to enter/scan "security card qr code" supposedly located in some recovery sheet that came with the wallet (which I don't have).

Can I just abort the process at this point (remove the device)?

[btchip]

No, keep going with a dummy card (for example 00000000000000000000000000000000) built from https://www.ledgerwallet.com/wallet/keycard
