Subject[PATCH] usb: serial: ti_usb_3410_5052: add MOXA UPORT 11x0 support
Date
Add support for :

- UPort 1110 : 1 port RS-232 USB to Serial Hub.
- UPort 1130 : 1 port RS-422/485 USB to Serial Hub.
- UPort 1130I : 1 port RS-422/485 USB to Serial Hub with Isolation.
- UPort 1150 : 1 port RS-232/422/485 USB to Serial Hub.
- UPort 1150I : 1 port RS-232/422/485 USB to Serial Hub with Isolation.

These devices are based on TI 3410 chip.

Hi,

This patch add support for MOXA UPORT 11x0 devices to ti_usb_3410_5052.
The informations are extracted from the now reverted mxu11x0 driver.

There is a delicate point in the attach callback.
The driver is comparing bNumConfigurations to 1 to see if the firmware
has to be downloaded. I guess bNumConfigurations is 2 after firmware download
and device reseting.

On MOXA 1110, bNumConfigurations is always 1, before and after firmware download.
So, I also check that the interface has only 1 endpoint to determine if we have
to download firmware or not.

Thanks,

Mathieu
