HWI issue, Error scaning, Trezor and Ledger not detected

[Shadovv007]

Hi,
I installed Sparrow and cant get detected any of my HW wallets, which work in other apps and with the same cable in the same usb spot. I did reboot, I dont use any other USB device, reinstalled Sparrow...dont know what else to try?

I ran hwi enumerate and got this :

Traceback (most recent call last):
File "hwi.py", line 7, in
File "hwilib_cli.py", line 305, in main

Thanks!

Which OS is that? Windows?

Which "other apps" does Trezor work with?

[Shadovv007]

Sorry, forgot to mention.. yes, its on Win 10.
On the same pc with the same conditions (cable, usb..) the Trezor works with Trezor Suite app, also here https://suite.trezor.io/ and also in Electrum desktop app.
Ledger works also in both Ledger live desktop app and in Electrum desktop app.
Thanks!

Try restarting the PC and do not launch Suite, but run Sparrow first. Did this help?

[Shadovv007]

Nope...when i click "Scan" both Trezor and Ledger give me still the same "There was error connecting to the wallet: Error scanning, check devices are ready" error.

Can this be a permission problem? Does it work when you run HWI as admin?

[Shadovv007]

Well, I didnt install HWI nor I knew about its existence/need before I wrote on Sparrow Telegram, where Craig Raw guided me to run "hwi enumerate" from Sparrow appdata\temp\ folder. But that hwi file was/is in "hwi-2.0.28140055849243990408.tmp" format.

So I was told to grab hwi from https://github.com/bitcoin-core/HWI/releases/download/2.0.2/hwi-2.0.2-windows-amd64.zip and run enumerate and results are posted above.
Should/need I install HWI ? Craig wrote, that Sparrow installs it itself in that temp location..
Could it also be something with Python? I used to play with it a little (just basic graphics) year ago and still have it installed.

Now I ran HWI as admin with these results:

Can you try without either Trezor suite or Electrum open, or anything else that may try to talk to the Trezor? This kind of error often appears when multiple apps are trying to use the device at the same time.

[Shadovv007]

Neither Trezor Suite nor Electrum is open :/
