hw.1 support
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
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?
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.
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.
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.
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!
oh in that case you can PM me an address on reddit and I'll send a few, should be faster
@btchip I PMed an address on reddit. Did you receive that PM? Just asking because otherwise I'll just buy a device.
received the btchips. Thanks a ton! Will share them with other electron-devs who they could be useful to.
great. Note that you'll need to flash them to the latest firmware using our Bitcoin Chrome app before they can be used
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)?
No, keep going with a dummy card (for example 00000000000000000000000000000000) built from https://www.ledgerwallet.com/wallet/keycard
Ledger Nano / HW1 actually work quite well now in Electron Cash. The only issue I still have is that message signing will not work, same as with Electrum. For message signing I need to unplug / replug the dongle to get the 2FA code, but after I enter it I first get asked for the PIN and then I get a status of '6b00', invalid parameter. This status is from signature = self.get_client().signMessageSign(pin) in sign_message. I checked the data sent and it looked good to me. I'll try to get a capture of the sent / received data and add that here later.
hi was this ever resolved? i have an old HW1 device with some bch on it, but won't let me export private key sent out all the btc, but now can't work it with electron b/c it's not supported there
@nimrodlehavi
won't let me export private key
that's by design. HW wallets do not give out private keys, they only sign transactions/messages.
now can't work it with electron b/c it's not supported there
I think it should be supported. Maybe ask in https://t.me/electroncashwallet
