2010-11-30 | usb-wwan: implement TIOCGSERIAL and TIOCSSERIAL to avoid blocking close(2) | Dan Williams | |
Some devices (ex ZTE 2726) simply don't respond at all when data is sent to some of their USB interfaces. The data gets stuck in the TTYs queue and sits there until close(2), which them blocks because closing_wait defaults to 30 seconds (even though the fd is O_NONBLOCK). This is rarely desired. Implement the standard mechanism to adjust closing_wait and let applications handle it how they want to. Signed-off-by: Dan Williams <dcbw@redhat.com> | |||
2010-05-20 | usb serial: Add generic USB wwan support | Matthew Garrett | |
The generic USB serial code is ill-suited for high-speed USB wwan devices, resulting in the option driver. However, other non-option devices may also gain similar benefits from not using the generic code. Factorise out the non-option specific code from the option driver and make it available to other users.
