Package: src:linux
Version: 5.10.46-4
Severity: wishlist

I am currently having to use the out of tree Exar USB Serial Driver
(xr_usb_serial_common) to talk to a modbus communication cable.
Last year, a reimplementation of that driver finally made mainline,
as CONFIG_USB_SERIAL_XR.

Looking at the metadata for CONFIG_USB_SERIAL_XR, it seems to support
my device:

vendor: 04e2 ("Exar Corp."), product: 1411, interface class: 02 ("Communications")

lsusb -v:

Bus 001 Device 005: ID 04e2:1411 Exar Corp. XR21B1411
Device Descriptor:
  bLength                18
  bDescriptorType         1
  bcdUSB               2.00
  bDeviceClass          239 Miscellaneous Device
  bDeviceSubClass         2 
  bDeviceProtocol         1 Interface Association
  bMaxPacketSize0        64
  idVendor           0x04e2 Exar Corp.
  idProduct          0x1411 
  bcdDevice            0.01
  iManufacturer           1 Exar Corp.
  iProduct                2 XR21B1411
  iSerial                 3 G9107376441
  bNumConfigurations      1

Also worth noting that Ubuntu has included the original Exar serial
module in their kernel tree for some time.
