[PATCH 6.6 73/93] cdc-acm: Add DISABLE_ECHO quirk for GE HealthCare UI Controller

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



6.6-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Ian Ray <ian.ray@xxxxxxxxxxxxxxxx>

commit 0b00583ecacb0b51712a5ecd34cf7e6684307c67 upstream.

USB_DEVICE(0x1901, 0x0006) may send data before cdc_acm is ready, which
may be misinterpreted in the default N_TTY line discipline.
