Hi @Bertrand256 , First of all, I'd like to say thank you very much for creating this DMT, appreciate it. Everything was working fine these few months. Until today when I updated the DMT to the latest version and the firmware+bridge for Trezor. After that, I'm unable to connect to my Trezor wallet via DMT. It shows LIBUSB_ERROR_IO (error attached in the pic). Here's what I experimented on: - Signed in on wallet.trezor, I'm able to send out my dash. - Signed in on wallet.trezor, then click the DMT wallet tab and clicked "Connect" the hardware wallet, it returns the error after 30 seconds or so. After that, if i try to send my DASH via wallet.trezor, it fails and shows the same LIBUSB_ERROR_IO message. It's like the DMT disconnects my trezor. DMT also doesnt show the balance. I would need to reconnect my trezor n sign in again to be able to send out my coins via wallet.trezor. DMT still no avail. - I used a different PC and I updated the DMT and firmware+bridge using the same steps. But I was able to see my balance this time and I assume I'd be able to send out my coins too. I tried reinstalling the trezor bridge on the problematic PC but still the same results. Is there a way to have a "clean reinstall" of DMT and wipe all potential files? Or any solution to my problem? Would appreciate your help. Thank you very much.
