Transport error in browser #193

Closed 4NobleTruths closed 4 years ago

4NobleTruths commented 4 years ago

Problem: Browser in appVM doesn't detect Trezor and gives "Transport error Error details: WebUSB is not available on this browser." and prompts to download the bridge.

(Other brands of hardware wallets work with their apps through same cable and configuration, in same appVM.)

Hardware: Trezor 1, unknown firmware version.

Environment: Qubes OS 4, Debian 9 appVM and sys-usb VM, Firefox-ESR 68.10.0esr (Dark Reader is the only extension installed.)

Configuration: https://wiki.trezor.io/Qubes_OS

Steps to replicate:

  1. Connect Trezor to USB-C port.
  2. sys-usb VM detects the device properly, and trezord service runs.
  3. Connect the Trezor device to appVM though widget.
  4. Device connects to appVM.
  5. Open browser and go to Trezor web wallet.

Are you running Trezor Bridge in the sys-usb vm?

Are you running Trezor Bridge in the sys-usb vm?

Yes, it's running only in sys-usb.

Can you open the following in your browser? http://127.0.0.1:21325/ - this is a status page from the Bridge

4NobleTruths commented 4 years ago

There is no browser in the sys-usb VM, but netstat says it's listening:

netstat -a | grep 21325 tcp 0 0 localhost:21325 0.0.0.0:* LISTEN

In the appVM, the browser on that URL says "The connection was reset", but netstat says also listen:

netstat -a | grep 21325 tcp 0 0 0.0.0.0:21325 0.0.0.0:* LISTEN
tcp 0 0 localhost:21325 localhost:42346 TIME_WAIT

Try asking @Kixunil - he seems to have trezor-bridge running on QubesOS: https://github.com/trezor/trezord-go/issues/163

He didn't respond. Maybe you @prusnak should ask him, so that you can answer this question when it comes up again?

So, the issue is really not closed - it's just punted. For me, the workaround is to migrate to other wallets.

Ranguvar commented 3 years ago

Similarly after setting up as described at https://wiki.trezor.io/Qubes_OS I am unable to connect to the device from the separate VM.

I can see trezord service is running on sys-usb and http://127.0.0.1:21325/ shows connected to device and working.

However, http://127.0.0.1:21325/ is not working on the AppVM which has the socat TCP-LISTEN:21325,fork EXEC:"qrexec-client-vm sys-usb trezord-service" & line in rc.local.

Neither does the https://wallet.trezor.io/ page detect any device.

If I first start the AppVM or explicitly run socat TCP-LISTEN:21325,fork EXEC:"qrexec-client-vm sys-usb trezord-service" in the AppVM I can then see it listening on port 21325 in `netstat -pln', but if I try to connect with browser it crashes:

socat[3835] E waitpid(): child 3878 exited with status 127

I then must restart the socat to get the port listening again, but I can never get any status page or the primary software to work.

@prusnak Sorry to bother -- any tips or hints for debugging this please?

Sorry. No clue. Please debug this with the Qubes OS community.

Kixunil commented 3 years ago

Wow, this flew over my head. I managed to get Trezor One running but without the bridge - I attach Trezor to my Electrum VM directly. I have no experience with any other configuration.
