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

That sounds reasonable.

Instead of storing the model (which really is the vid-dependent pid),
just set an rs485-only flag when you detect a Moxa 1130/1131 here.

Indent continuation lines two tabs further, or rewrite so that you don't
need a line break.

Use the flag set mentioned above instead.

Looks like this code could use a few vid/pid temporaries.
I'm not sure it makes sense to try to load a "ti_usb-v110a-p1150.fw"
firmware before requesting the moxa firmware. Avoids a confusing:
usb 1-2.2: Direct firmware load for ti_usb-v110a-p1150.fw failed with error -2
message too.

I did a quick test of the patch using a Moxa 1150-device. Works at
115200, but communication appeared broken at 9600. Looks like the baud
rate calculations are similar but not identical to what the Moxa driver
does. Is this something you have looked into?
Thanks,
