Ftdi problems on android

Mon Jun 4 03:48:53 PDT 2018

Like a number of people I can't download using FTDI anymore.

I have a suunto 4i and use a OTG cable. I'm running lollipop.

I reloaded old test versions and the last release to download correctly is 4.7.4.280 , the 4.7.5 that followed and all since have failed to download.

Attached is the log from a recent version after trying a few times to connect.
