USB transport not working

[freundTech]

Hello,
I'm planing on using this library and wanted to test it using https://github.com/cotechde/fido-browser.

Using my security key using NFC works find, however when connecting via USB first Android asks me if I want to allow Fido-Browser to access the USB device. After I select Ok nothing happens.

I compiled a debug build of fido-browser and got the following stacktrace:

E/SecurityKeyManager: Failed initial connection with card

I tested using a SoloKeys USB-C + NFC security key and both an Xiaomi Mi 9T and LG G6 android phone.
