Hi,
I encountered an issue when trying to connect an EQ6 (EQMod) to a Raspberry Pi (Raspbian) via a powered USB 2.0 hub. It works fine for some time but then suddenly gives these errors in the INDI control panel:
2016-10-19T10:43:48: Disconnected from EQMod Mount.
2016-10-19T10:43:48: Error: -> tty write failed, check connection: Error: unrecognized error code
2016-10-19T10:43:47: Disconnected from EQMod Mount.
2016-10-19T10:43:47: Error: -> tty read failed, check connection: Timeout error
The write error and disconnect messages then repeat infinitely and the mount doesn't react until disconnecting and connecting again from Ekos or the INDI control panel. After some time, the error occurs again. It always begins with the timeout error, followed by the write errors. On a Pi 2, it takes a long time for the error to occur (one or half an hour) on a Pi Zero it occurs within minutes after connecting to the mount from Ekos.
When connecting the mount to a USB port on the Pi 2 directly, the error doesn't seem to occur (tested ~4-5 hours during observation).
I already checked the permission stuff: adding user to dialout, serial port mapping and changing permissions of ttyUSB, but to no avail.
Attached you find the verbose mount log and the serial log, they don't seem to contain much more information on the errors however. The driver output is quite long but also contains the messages.
