Keep Key issue

[cAP5L0CK]

I have been able to set up both my ledger and my trezor, but when I try to add the keep key I get all the way to the dialog that asks for the password (BIP39). I enter it, and at this point I would expect it would appear on the Keep Key after hitting submit but it does not. And I get this error in the screenshot:

It SEEMS as if it skips over the part where it sends to the keep key and waits for a response. It does handle the PIN correctly.

I am using BOTH the latest firmware on the keep key, as well as the latest specter I think
Bootloader 1.1.0
Firmware 7.1.2
Specter:1.4.2

(What a great project this is, by the way... VERY well done.)

Update.

Decided to try to run on a different platform. Ran the appimage on Arch Linux. Did the UDEV dance. Keepkey immediately recognized.

EXACT same issue at the password prompt.

So, seems not dependent on the OS.

Wish I was a coder... I am combing through what i can to try to find the password part of the whole handshake. Sort of looks like it was written using a lot of the same stuff the trezor is using. If I find anything that looks promising I will say. I have a feeling something might just be out of order, or a function is just not being called.

Ran in python instead of executable so we could see the python output. Here is what it says when the error happens:

Glad to provide any other testing or information if needed. Let me know.

Hi, can you try upgrading the KeepKey firmware and retry please?

[cAP5L0CK]

I have had Bootloader 1.1.0 and Firmware 7.1.4 since starting with Keepkey/Specter..

These are both the latest (I think) and the updater gives no option to flash them again.

[cAP5L0CK]

I thought I would try to document this a little better. If there is a place in the code maybe I could go to and fix it (I wish I could help more) I would not mind trying.

So I:

1. +Add New Device (CHECK)
2. Enter Name (CHECK)
3. Get via USB (CHECK)
4. The device is recognized and shows the PIN screen
5. Enter PIN (CHECK)
6. The Device now says "Passphrase Confirmation" (CHECK)
7. I am presented with the passphrase dialog on the computer (CHECK)
   
8. I input the passphrase (CHECK)
9. Click Submit (THIS IS WHERE WE GO OFF THE RAILS)

At this point the software returns the following errors:

And the device has not changed since step 6. It is still in a state of waiting for the password.

So it seems to me this is basically running the Trezor script, and at the point the software needs to SEND the passphrase to the device it does NOT send it, and instead polls the device for it's response and executes the GetFeatures function. But the device, having not yet received the passphrase does not respond as expected... and there we are.

I am assuming either we are skipping the send passphrase part, or executing it incorrectly. I have been looking through the code but my novice level understanding is lost trying to pinpoint the place at which what we want to happen is not happening.

Hopefully this provides some more clarity. If there is a particular function in the code i should be looking at I would be glad to try to continue to see what I can do... just let me know!

Just an update:

Issue persists with firmware 7.2.1(latest, within the week)

Another interesting detail. Sparrow Wallet seems to fail with the keepkey in exactly the same way. Wondering if the codebase is shared?
