Subject: [PATCH v2 0/2] usb: serial: add support for CH348
Hello
The CH348 is an octo serial to USB adapter.
The following patch adds a driver for supporting it.
Since there is no public datasheet, unfortunatly it remains some magic values.
It was tested with a large range of baud from 1200 to 1500000 and used with
success in one of our kernel CI testlab.
Regards
Changes since v1:
- use a data structure for encoding/decoding messages.
- check if needed endpoints exists
- fix URB leak in ch348_allocate_status_read error case
- test for maximum baud rate as stated by datasheet
