Upload fails on certain USB-TTL adapters #24

Closed brahmafear closed 7 years ago

brahmafear commented 7 years ago

Plugin works for me when using certain USB-TTL adapters but fails (freezes progress) on certain models. Posting here in case anyone has seen same issue. Tested with two models of problem

adapter listed below - both show same issue. (Both work perfectly when uploading sketch from IDE.)

Mac OS X 10.11.6 Arduino IDE 1.6.12 USB-TTL prodID 6001, vendID 0403

Note: this USB-TTL adapter is supposedly an FTDI chip, but since I got them for cheap online, I'm open to the possibility that they are clones. However, posting issue in case this is indicative of a problem in the plugin code.

Attached file shows where progress in IDE upload freezes. This is running the upload plugin on the FSBrowser example sketch in ESPWebServer package.

More info: only way to "unfreeze" the IDE is to disconnect the USB connection to the USB-TTL adapter. Upon doing so, the following is shown in the IDE:

this looks like FTDI adapter. See to update the driver and preferably have it connected through USB hub. It's something to do with USB on Mac

brahmafear commented 7 years ago

Very possible. In either case, I can work around by using a different adapter. Will mark issue as closed. The thread will remain searchable in case it happens to anyone else in future. Thanks.

More info for future: Installed official FTDI v2.3 driver for OSX instead of using OSX built-in driver for FTDI: same issue, same behavior. Will test with USB hub when possible. Will blame issue on shady FTDI clone chip.
