Probably you just have to wait for a couple more days for trezor to fix the issue, they were not expecting this to happen anytime soon and since it just did they will fix it. The trezor was intended for bitcoin and some altcoins but does not support all of them yet so we will just have to wait and see.

OK, here it is the 8th Aug and I seem to have updated firmware OK but there is no BCC-BCH
wallet showing. Anybody know what is going on? I want to store a few BCH but this is making
me leery. Does the Ledger Nano have a working BitcoinCash wallet?
