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.
