  • Python 2.7
  • Nano S - open at dashboard
  • ECPy version==0.8.1 (to get around 'ECPy requires Python '>=3' but the running Python is 2.7.13' issue)

Command:
$ python -m ledgerblue.runApp --targetId 0x31100002 --appName Bitcoin

Trace:

Traceback (most recent call last):

    raise CommException("Invalid status %04x" % sw, sw, response)
ledgerblue.commException.CommException: Exception : Invalid status 6d00

results appear to be the same regardless of the argument passed to --appName (or whether or not the argument is enclosed in quotes).

Add support for more device statuses
576064d 
Before this change, tools like `ledger-agent` [1] give cryptic errors
like the following if the device has the Bitcoin app or the dashboard
open:

```
ledgerblue.commException.CommException: Exception : Invalid status 6d00 (Unknown reason)
ledgerblue.commException.CommException: Exception : Invalid status 6e00 (Unknown reason)
```

After this change, we try to provide a hint that there's nothing wrong
with the device, but that it's in an unexpected state.

Fixes LedgerHQ#26 LedgerHQ#31.

@btchip: Do you think we can close this issue as well, with #67 merged?

(I intended to close both this issue and #26 automatically by merging #67, but apparently 'Fixes #26 #31' isn't understood by Github..)
