I connected my metamask with binance server so that my metamask could do bep20. I connected my metamask with my trezor. Then I deposited BNB into the trezor address. The new BNB balance appeared in the trezor address. Now I could not withdraw or transfer my BNB from the trezor address to any where else. When I tried to send BNB from trezor account to normal account within the metamask, it did not do anything.
I think I have solved my problem by accessing myetherwallet using trezor then send the coins from there.
